Abstract

Strong motivation for investing in quantum sensing arises from the need to investigate phenomena that are very weakly coupled to the matter and fields well described by the Standard Model. These can be related to the problems of dark matter, dark sectors not necessarily related to dark matter (for example sterile neutrinos), dark energy and gravity, fundamental constants, and problems with the Standard Model itself including the Strong CP problem in QCD. Resulting experimental needs typically involve the measurement of very low energy impulses or low power periodic signals that are normally buried under large backgrounds. This report documents the findings of the 2023 Quantum Sensors for High Energy Physics workshop which identified enabling quantum information science technologies that could be utilized in future particle physics experiments, targeting high energy physics science goals., Comment: 63 pages, 8 figures, Quantum Sensors for HEP workshop report, April 26-28, 2023

Abstract

The performance of superconducting qubits is degraded by a poorly characterized set of energy sources breaking the Cooper pairs responsible for superconductivity, creating a condition often called "quasiparticle poisoning." Recently, a superconductor with one of the lowest average quasiparticle densities ever measured exhibited quasiparticles primarily produced in bursts which decreased in rate with time after cooldown. Similarly, several cryogenic calorimeters used to search for dark matter have also observed an unknown source of low-energy phonon bursts that decrease in rate with time after cooldown. Here, we show that a silicon crystal glued to its holder exhibits a rate of low-energy phonon events that is more than two orders of magnitude larger than in a functionally identical crystal suspended from its holder in a low-stress state. The excess phonon event rate in the glued crystal decreases with time since cooldown, consistent with a source of phonon bursts which contributes to quasiparticle poisoning in quantum circuits and the low-energy events observed in cryogenic calorimeters. We argue that relaxation of thermally induced stress between the glue and crystal is the source of these events, and conclude that stress relaxation contributes to quasiparticle poisoning in superconducting qubits and the athermal phonon background in a broad class of rare-event searches.

3. Calorimetric observation of single He2* excimers in a 100 mK He bath

Author

Carter, Faustin W., Hertel, Scott A., McClintock, Peter Vaughan Elsmere, McKinsey, Daniel N., Prober, Daniel E., Carter, Faustin W., Hertel, Scott A., McClintock, Peter Vaughan Elsmere, McKinsey, Daniel N., and Prober, Daniel E.

Abstract

We report the first calorimetric detection of individual He2* excimers within a bath of superfluid 4He. The detector used in this work is a single superconducting titanium transition edge sensor (TES) with an energy resolution of 1 eV, immersed directly in the helium bath. He2* excimers are produced in the surrounding bath using an external gamma-ray source. These excimers exist either as short-lived singlet or long-lived triplet states. We demonstrate detection (and discrimination) of both states: in the singlet case the calorimeter records the absorption of a prompt 15 eV photon, and in the triplet case the calorimeter records a direct interaction of the molecule with the TES surface, which deposits a distinct fraction of the 15 eV, released upon decay, into the surface. We also briefly discuss the detector fabrication and characterization.

Abstract

The SuperCDMS collaboration is presently operating a 9 kg Ge payload at the Soudan Underground Laboratory in their direct search for dark matter. The Ge detectors utilize double-sided athermal phonon sensors with an interdigitated electrode structure (iZIPs) to reject near-surface electron-recoil events. These detectors each have a mass of 0.6 kg and were fabricated with photolithographic techniques. The detector fabrication advances required and the production yield encountered are described., United States. Dept. of Energy, National Science Foundation (U.S.)

Abstract

CDMS II data from the five-tower runs at the Soudan Underground Laboratory were reprocessed with an improved charge-pulse fitting algorithm. Two new analysis techniques to reject surface-event backgrounds were applied to the 612 kg days germanium-detector weakly interacting massive particle (WIMP)-search exposure. An extended analysis was also completed by decreasing the 10 keV analysis threshold to ~5 keV, to increase sensitivity near a WIMP mass of 8 GeV/c[superscript 2]. After unblinding, there were zero candidate events above a deposited energy of 10 keV and six events in the lower-threshold analysis. This yielded minimum WIMP-nucleon spin-independent scattering cross-section limits of 1.8 × 10[superscript −44] and 1.18 × 10[superscript −41] at 90% confidence for 60 and 8.6 GeV/c[superscript 2] WIMPs, respectively. This improves the previous CDMS II result by a factor of 2.4 (2.7) for 60 (8.6) GeV/c[superscript 2] WIMPs., National Science Foundation (U.S.), United States.

Abstract

We report on the results of a search for a Weakly Interacting Massive Particle (WIMP) signal in low-energy data of the Cryogenic Dark Matter Search experiment using a maximum likelihood analysis. A background model is constructed using geant4 to simulate the surface-event background from [superscript 210]Pb decay-chain events, while using independent calibration data to model the gamma background. Fitting this background model to the data results in no statistically significant WIMP component. In addition, we perform fits using an analytic ad hoc background model proposed by Collar and Fields, who claimed to find a large excess of signal-like events in our data. We confirm the strong preference for a signal hypothesis in their analysis under these assumptions, but excesses are observed in both single- and multiple-scatter events, which implies the signal is not caused by WIMPs, but rather reflects the inadequacy of their background model., United States.

Abstract

While the standard model of particle physics does not include free particles with fractional charge, experimental searches have not ruled out their existence. We report results from the Cryogenic Dark Matter Search (CDMS II) experiment that give the first direct-detection limits for cosmogenically produced relativistic particles with electric charge lower than e/6. A search for tracks in the six stacked detectors of each of two of the CDMS II towers finds no candidates, thereby excluding new parameter space for particles with electric charges between e/6 and e/200., National Science Foundation (U.S.), United States.

Abstract

We report a first search for weakly interacting massive particles (WIMPs) using the background rejection capabilities of SuperCDMS. An exposure of 577 kg days was analyzed for WIMPs with mass < 30 GeV/c[superscript 2], with the signal region blinded. Eleven events were observed after unblinding. We set an upper limit on the spin-independent WIMP-nucleon cross section of 1.2 × 10[superscript −42] cm[superscript 2] at 8 GeV/c[superscript 2]. This result is in tension with WIMP interpretations of recent experiments and probes new parameter space for WIMP-nucleon scattering for WIMP masses <6 GeV/c[superscript 2]., National Science Foundation (U.S.), United States.

Abstract

The SuperCDMS experiment in the Soudan Underground Laboratory searches for dark matter with a 9-kg array of cryogenic germanium detectors. Symmetric sensors on opposite sides measure both charge and phonons from each particle interaction, providing excellent discrimination between electron and nuclear recoils, and between surface and interior events. Surface event rejection capabilities were tested with two [superscript 210] Pb sources producing ∼130 beta decays/hr. In ∼800 live hours, no events leaked into the 8–115 keV signal region, giving upper limit leakage fraction 1.7 × 10[superscript −5] at 90% C.L., corresponding to < 0.6 surface event background in the future 200-kg SuperCDMS SNOLAB experiment., United States.

Abstract

SuperCDMS is an experiment designed to directly detect weakly interacting massive particles (WIMPs), a favored candidate for dark matter ubiquitous in the Universe. In this Letter, we present WIMP-search results using a calorimetric technique we call CDMSlite, which relies on voltage-assisted Luke-Neganov amplification of the ionization energy deposited by particle interactions. The data were collected with a single 0.6 kg germanium detector running for ten live days at the Soudan Underground Laboratory. A low energy threshold of 170 eV[subscript ee] (electron equivalent) was obtained, which allows us to constrain new WIMP-nucleon spin-independent parameter space for WIMP masses below 6 GeV/c[superscript 2]., National Science Foundation (U.S.), United States.

Abstract

We report results of a search for weakly interacting massive particles (WIMPS) with the silicon detectors of the CDMS II experiment. This blind analysis of 140.2 kg day of data taken between July 2007 and September 2008 revealed three WIMP-candidate events with a surface-event background estimate of 0.41[+0.20 over −0.08](stat)[+0.28 over −0.24](syst). Other known backgrounds from neutrons and [superscript 206]Pb are limited to < 0.13 and < 0.08 events at the 90% confidence level, respectively. The exposure of this analysis is equivalent to 23.4 kg day for a recoil energy range of 7–100 keV for a WIMP of mass 10 GeV/c[superscript 2]. The probability that the known backgrounds would produce three or more events in the signal region is 5.4%. A profile likelihood ratio test of the three events that includes the measured recoil energies gives a 0.19% probability for the known-background-only hypothesis when tested against the alternative WIMP + background hypothesis. The highest likelihood occurs for a WIMP mass of 8.6 GeV/c[superscript 2] and WIMP-nucleon cross section of 1.9 × 10[superscript −41] cm[superscript 2]., National Science Foundation (U.S.) (Grant AST-9978911), National Science Foundation (U.S.) (Grant NSF-0847342), National Science Foundation (U.S.) (Grant NSF-1151869), National Science Foundation (U.S.) (Grant PHY-0542066), National Science Foundation (U.S.) (Grant PHY-0503729), National Science Foundation (U.S.) (Grant PHY-0503629), National Science Foundation (U.S.) (Grant PHY-0503641), National Science Foundation (U.S.) (Grant PHY-0504224), National Science Foundation (U.S.) (Grant PHY-0705052), National Science Foundation (U.S.) (Grant PHY-0801708), National Science Foundation (U.S.) (Grant PHY-0801712), National Science Foundation (U.S.) (Grant PHY-0802575), National Science Foundation (U.S.) (Grant PHY-0847342), National Science Foundation (U.S.) (Grant PHY-0855299), National Science Foundation (U.S.) (Grant PHY-0855525), National Science Foundation (U.S.) (Grant PHY-1102795), National Science Foundation (U.S.) (Grant PHY-1205898), United States.

Abstract

We report a first search for weakly interacting massive particles (WIMPs) using the background rejection capabilities of SuperCDMS. An exposure of 577 kg days was analyzed for WIMPs with mass < 30 GeV/c[superscript 2], with the signal region blinded. Eleven events were observed after unblinding. We set an upper limit on the spin-independent WIMP-nucleon cross section of 1.2 × 10[superscript −42] cm[superscript 2] at 8 GeV/c[superscript 2]. This result is in tension with WIMP interpretations of recent experiments and probes new parameter space for WIMP-nucleon scattering for WIMP masses <6 GeV/c[superscript 2]., National Science Foundation (U.S.), United States.

Abstract

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Physics, 2012., Cataloged from PDF version of thesis., Includes bibliographical references (p. 285-294)., An overwhelming proportion of the universe (83% by mass) is composed of particles we know next to nothing about. Detecting these dark matter particles directly, through hypothesized weak-force-mediated recoils with nuclear targets here on earth, could shed light on what these particles are, how they relate to the standard model, and how the standard model fits within a more fundamental understanding. This thesis describes two such experimental efforts: CDMS 11 (2007-2009) and SuperCDMS Soudan (ongoing). The general abilities and sensitivities of both experiments are laid out, placing a special emphasis on the detector technology, and how this technology has evolved from the first to the second experiment. Some topics on which I spent significant efforts are described here only in overview (in particular the details of the CDMS II analysis, which has been laid out many times before), and some topics which are not described elsewhere are given a somewhat deeper treatment. In particular, this thesis is hopefully a good reference for those interested in the annual modulation limits placed on the low-energy portion of the CDMS II exposure, the design of the detectors for SuperCDMS Soudan, and an overview of the extremely informative data these detectors produce. It is an exciting time. The technology I've had the honor to work on the past few years provides a wealth of information about each event, more so than any other direct detection experiment, and we are still learning how to optimally use all this information. Initial tests from the surface and now underground suggest this technology has the background rejection abilities necessary for a planned 200kg experiment or even ton-scale experiment, putting us on the threshold of probing parameter space orders of magnitude from where the field currently stands., by Scott A.

Abstract

We report results of a search for weakly interacting massive particles (WIMPs) with the Si detectors of the CDMS II experiment. This report describes a blind analysis of the first data taken with CDMS II’s full complement of detectors in 2006–2007; results from this exposure using the Ge detectors have already been presented. We observed no candidate WIMP-scattering events in an exposure of 55.9 kg-days before analysis cuts, with an expected background of ∼1.1 events. The exposure of this analysis is equivalent to 10.3 kg-days over a recoil energy range of 7–100 keV for an ideal Si detector and a WIMP mass of 10 GeV/c[superscript 2]. These data set an upper limit of 1.7×10[superscript -41] cm[superscript 2] on the WIMP-nucleon spin-independent cross section of a 10 GeV/c[superscript 2] WIMP. These data exclude parameter space for spin-independent WIMP-nucleon elastic scattering that is relevant to recent searches for low-mass WIMPs., National Science Foundation (U.S.), United States.

Abstract

The CDMS and EDELWEISS collaborations have combined the results of their direct searches for dark matter using cryogenic germanium detectors. The total data set represents 614 kg·days equivalent exposure. A straightforward method of combination was chosen for its simplicity before data were exchanged between experiments. The results are interpreted in terms of limits on spin-independent weakly interacting, massive particle (WIMP)-nucleon cross section. For a WIMP mass of 90 GeV/c[superscript 2], where this analysis is most sensitive, a cross section of 3.3×10[superscript -44] cm[superscript 2] is excluded at 90% C.L. At higher WIMP masses, the combination improves the individual limits, by a factor 1.6 above 700 GeV/c[superscript 2].

Abstract

Results are presented from a reanalysis of the entire five-tower data set acquired with the Cryogenic Dark Matter Search (CDMS II) experiment at the Soudan Underground Laboratory, with an exposure of 969 kg-days. The analysis window was extended to a recoil energy of 150 keV, and an improved surface-event background-rejection cut was defined to increase the sensitivity of the experiment to the inelastic dark matter (iDM) model. Three dark matter candidates were found between 25 keV and 150 keV. The probability to observe three or more background events in this energy range is 11%. Because of the occurrence of these events, the constraints on the iDM parameter space are slightly less stringent than those from our previous analysis, which used an energy window of 10–100 keV., National Science Foundation (U.S.) (Grant AST-9978911), National Science Foundation (U.S.) (Grant PHY-0542066), National Science Foundation (U.S.) (Grant PHY-0503729), National Science Foundation (U.S.) (Grant PHY-0503629), National Science Foundation (U.S.) (Grant PHY-0503641), National Science Foundation (U.S.) (Grant PHY-0504224), National Science Foundation (U.S.) (Grant PHY-0705052), National Science Foundation (U.S.) (Grant PHY-0801708), National Science Foundation (U.S.) (Grant PHY-0801712), National Science Foundation (U.S.) (Grant PHY-0802575), National Science Foundation (U.S.) (Grant PHY-0855525), United States.

Abstract

We report results from a reanalysis of data from the Cryogenic Dark Matter Search (CDMS II) experiment at the Soudan Underground Laboratory. Data taken between October 2006 and September 2008 using eight germanium detectors are reanalyzed with a lowered, 2 keV recoil-energy threshold, to give increased sensitivity to interactions from weakly interacting massive particles (WIMPs) with masses below ∼10 GeV/c2 [Ge V / c superscript 2]. This analysis provides stronger constraints than previous CDMS II results for WIMP masses below 9 GeV/c2 [Ge V / c superscript 2] and excludes parameter space associated with possible low-mass WIMP signals from the DAMA/LIBRA and CoGeNT experiments., National Science Foundation (U.S.) (Grant AST-9978911), National Science Foundation (U.S.) (Grant PHY-0542066), National Science Foundation (U.S.) (Grant PHY-0503729), National Science Foundation (U.S.) (Grant PHY-0503629), National Science Foundation (U.S.) (Grant PHY-0503641), National Science Foundation (U.S.) (Grant PHY-0705052), National Science Foundation (U.S.) (Grant PHY-0504224), National Science Foundation (U.S.) (Grant PHY-0801708), National Science Foundation (U.S.) (Grant PHY-0801712), National Science Foundation (U.S.) (Grant PHY-0802575), National Science Foundation (U.S.) (Grant PHY-0847342), National Science Foundation (U.S.) (Grant PHY-0855525), United States.

Abstract

We report on the analysis of the low-energy electron-recoil spectrum from the CDMS II experiment using data with an exposure of 443.2 kg-days. The analysis provides details on the observed counting rate and possible background sources in the energy range of 2–8.5 keV. We find no significant excess of a peaked contribution to the total counting rate above the background model, and compare this observation to the recent DAMA results. In the framework of a conversion of a dark matter particle into electromagnetic energy, our 90% confidence level upper limit of 0.246 events/kg/day at 3.15 keV is lower than the total rate above background observed by DAMA. In absence of any specific particle physics model to provide the scaling in cross section between NaI and Ge, we assume a Z2 scaling. With this assumption the observed rate in DAMA remains higher than the upper limit in CDMS. Under the conservative assumption that the modulation amplitude is 6% of the total rate we obtain upper limits on the modulation amplitude a factor of ∼2 lower than observed by DAMA, constraining some possible interpretations of this modulation., National Science Foundation ((Grant Nos.

Abstract

We report on the first axion search results from the Cryogenic Dark Matter Search (CDMS) experiment at the Soudan Underground Laboratory. An energy threshold of 2 keV for electron-recoil events allows a search for possible solar axion conversion into photons or local galactic axion conversion into electrons in the germanium crystal detectors. The solar axion search sets an upper limit on the Primakov coupling g[subscript aγγ] of 2.4×10[superscript -9] GeV[superscript -1] at the 95% confidence level for an axion mass less than 0.1 keV/c[superscript 2]. This limit benefits from the first precise measurement of the absolute crystal plane orientations in this type of experiment. The galactic axion search analysis sets a world-leading experimental upper limit on the axioelectric coupling g[subscript ae[over-bar] e] of 1.4×10[superscript -12] at the 90% confidence level for an axion mass of 2.5 keV/c[superscript 2]., Natural Sciences and Engineering Research Council of Canada (Grant SAPIN 341314-07), Swiss National Science Foundation (SNF Grant No. 20-118119), United States Department of Energy ((Contracts No. DE-AC03-76SF00098, No. DE-FG02-91ER40688, No. DE-FG02-92ER40701, No. DE-FG03-90ER40569, and No. DE-FG03-91ER40618), National Science Foundation (Grant No. AST-9978911, No. PHY-0542066, No. PHY-0503729, No. PHY-0503629, No. PHY-0503641, No. PHY-0504224, and No. PHY- 0705052)

Abstract

We report results from the Cryogenic Dark Matter Search at the Soudan Underground Laboratory (CDMS II) featuring the full complement of 30 detectors. A blind analysis of data taken between October 2006 and July 2007 sets an upper limit on the weakly interacting massive particle (WIMP) nucleon spin-independent cross section of 6.6×10[superscript -44] cm[superscript 2] (4.6×10[superscript -44] cm[superscript 2] when combined with previous CDMS II data) at the 90% confidence level for a WIMP mass of 60 GeV/c[superscript 2]. This achieves the best sensitivity for dark matter WIMPs with masses above 44 GeV/c[superscript 2], and significantly restricts the parameter space for some favored supersymmetric models., Natural Sciences and Engineering Research Council of Canada (Grant SAPIN No. 341314-07), Swiss National Science Foundation (SNF Grant No. 20-118119), United States Department of Energy (Contracts DE-AC03-76SF00098, DE-FG02-91ER40688, DE-FG03-90ER40569, and DEFG03- 91ER40618), National Science Foundation (Grant Nos.

Abstract

We report on the analysis of the low-energy electron-recoil spectrum from the CDMS II experiment using data with an exposure of 443.2 kg-days. The analysis provides details on the observed counting rate and possible background sources in the energy range of 2–8.5 keV. We find no significant excess of a peaked contribution to the total counting rate above the background model, and compare this observation to the recent DAMA results. In the framework of a conversion of a dark matter particle into electromagnetic energy, our 90% confidence level upper limit of 0.246 events/kg/day at 3.15 keV is lower than the total rate above background observed by DAMA. In absence of any specific particle physics model to provide the scaling in cross section between NaI and Ge, we assume a Z2 scaling. With this assumption the observed rate in DAMA remains higher than the upper limit in CDMS. Under the conservative assumption that the modulation amplitude is 6% of the total rate we obtain upper limits on the modulation amplitude a factor of ∼2 lower than observed by DAMA, constraining some possible interpretations of this modulation., National Science Foundation ((Grant Nos.
