Abstract

We present limits on the spin-independent interaction cross section of dark matter particles with silicon nuclei, derived from data taken with a cryogenic calorimeter with 0.35 g target mass operated in the CRESST-III experiment. A baseline nuclear recoil energy resolution of $(1.36\pm 0.05)$ eV$_{\text{nr}}$, currently the lowest reported for macroscopic particle detectors, and a corresponding energy threshold of $(10.0\pm 0.2)$ eV$_{\text{nr}}$ have been achieved, improving the sensitivity to light dark matter particles with masses below 160 MeV/c$^2$ by a factor of up to 20 compared to previous results. We characterize the observed low energy excess, and we exclude noise triggers and radioactive contaminations on the crystal surfaces as dominant contributions., Comment: 8 pages, 5 figures; precised the position of the calibration source in Fig. 1; extended the discussion about the observed energy spectrum; added the DM limit curve to ancillary files.

Abstract

The CRESST experiment observes an unexplained excess of events at low energies. In the current CRESST-III data-taking campaign we are operating detector modules with different designs to narrow down the possible explanations. In this work, we show first observations of the ongoing measurement, focusing on the comparison of time, energy and temperature dependence of the excess in several detectors. These exclude dark matter, radioactive backgrounds and intrinsic sources related to the crystal bulk as a major contribution., Comment: 10 pages, 5 figures; to be published in IDM2022 proceedings; corrected several minor typos

Abstract

The CRESST experiment searches for dark matter induced nuclear recoils inside CaWO4 based cryogenic calorimeters at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. To identify reliably a potential signal, a precise understanding of its background budget is crucial. An important background category could be “cosmogenics”: radionuclides produced via interactions with cosmic rays, mainly during the crystal production at surface facilities. Albeit CaWO4 is a well-established calorimetric material, no systematic study of its susceptibility for cosmic activation existed so far. In this contribution, we will first report the exposure profile of CRESST’s in-house grown TUM93 crystal to cosmic rays. Then we will identify the most prominent cosmogenics via AcTIVIA calculations. Afterwards we discuss the expected background spectrum based on Geant4 simulations and compare it to measurements.

Abstract

In CRESST-III, 10 cryogenic detector modules optimized for low energy thresholds were operated for almost two years (May 2016 - February 2018). Together with this document we are publishing data from the best performing detector module which has a nuclear recoil threshold of 30.1eV. With this data-set we were able to set limits on the cross-section for spin-dependent and spin-independent elastic scattering of dark matter particles off nuclei at dark matter masses down to 160MeV/c$^2$. We publish the energies of all events after data selection as well as of all events within the acceptance region for dark-matter searches. In this document we describe how to use these data sets., Comment: Added appendix with information for better reproducibility

Abstract

The CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) dark matter search experiment aims for the detection of dark matter particles via elastic scattering off nuclei in $\mathrm{CaWO_4}$ crystals. To understand the CRESST electromagnetic background due to the bulk contamination in the employed materials, a model based on Monte Carlo simulations was developed using the Geant4 simulation toolkit. The results of the simulation are applied to the TUM40 detector module of CRESST-II phase 2. We are able to explain up to $(68 \pm 16)\,\mathrm{\%}$ of the electromagnetic background in the energy range between $1\,\mathrm{keV}$ and $40\,\mathrm{keV}$., Comment: 19 pages, 12 figures

Abstract

Scintillating, cryogenic bolometers are widely used in the field of rare event searches. Their main advantages are an excellent energy resolution and particle identification on an event-by-event basis. The sensitivity of experiments applying this detector technique can be limited by the performance of the light channel and the presence of external backgrounds in the region of interest. In the framework of the CRESST-II experiment, we developed and successfully tested a novel detector design addressing both challenges. Using a large scale ($\approx$\unit[60]{cm$^2$}), beaker-shaped silicon light absorber, the signal height recorded in the light channel is improved by a factor 2.5 compared to conventional CRESTT-II detector modules. In combination with a large carrier crystal, a true $4��$ veto system is established which allows to tag external background sources., 7 pages, 5 fugures, submitted to EPJ-C

Previous stages established leading limits for the spin-independent DM-nucleon cross section down to DM-particle masses $m_\mathrm{DM}$ below $1\,\mathrm{GeV/c^2}$. Furthermore, CRESST performed a dedicated search for dark photons (DP) which excludes new parameter space between DP masses $m_\mathrm{DP}$ of $300\,\mathrm{eV/c^2}$ to $700\,\mathrm{eV/c^2}$. In this contribution we will discuss the latest results based on the previous CRESST-II phase 2 and we will report on the status of the current CRESST-III phase 1: in this stage we have been operating 10 upgraded detectors with $24,\mathrm{g}$ target mass each and enhanced detector performance since summer 2016. The improved detector design in terms of background suppression and reduction of the detection threshold will be discussed with respect to the previous stage. We will conclude with an outlook on the potential of the next stage, CRESST-III phase 2., Published by Verlag Deutsches Elektronen-Synchrotron, Hamburg

Together with this document we are publishing data from two detector modules which have been used for direct dark-matter searches. With these data-sets we were able to set world-leading limits on the cross section for spin-independent elastic scattering of dark matter particles off nuclei. We publish the energies of all events within the acceptance regions for dark-matter searches. In addition, we also publish the energies of the events within the electron-recoil band. This data set can be used to study interactions with electrons of CaWO$_4$. In this document we describe how to use these data sets. In particular, we explain the cut-survival probabilities required for comparisons of models with the data sets., Comment: Text unchanged to v2, new ancillary files added containing simulated data for the sensitivity projections of CRESST-III phase 2 with 1 tonne day exposure, additional information may be found in anc/Proj_CRESST-III-Phase2_README.txt

Abstract

Models for light dark matter particles with masses below 1 GeV/c$^2$ are a natural and well-motivated alternative to so-far unobserved weakly interacting massive particles. Gram-scale cryogenic calorimeters provide the required detector performance to detect these particles and extend the direct dark matter search program of CRESST. A prototype 0.5 g sapphire detector developed for the $\nu$-cleus experiment has achieved an energy threshold of $E_{th}=(19.7\pm 0.9)$ eV, which is one order of magnitude lower than previous results and independent of the type of particle interaction. The result presented here is obtained in a setup above ground without significant shielding against ambient and cosmogenic radiation. Although operated in a high-background environment, the detector probes a new range of light-mass dark matter particles previously not accessible by direct searches. We report the first limit on the spin-independent dark matter particle-nucleon cross section for masses between 140 MeV/c$^2$ and 500 MeV/c$^2$., Comment: 6 pages, 6 figures, v3: ancillary files added, v4: high energy spectrum (0.6-12keV) added to ancillary files

Abstract

In the past years the spotlight of the search for dark matter particles widened to the low mass region, both from theoretical and experimental side. We discuss results from data obtained in 2013 with a single detector TUM40. This detector is equipped with a new upgraded holding scheme to efficiently veto backgrounds induced by surface alpha decays. This veto, the low threshold of 0.6keV and an unprecedented background level for CaWO$_4$ target crystals render TUM40 the detector with the best overall performance of CRESST-II phase 2 (July 2013 - August 2015). A low-threshold analysis allowed to investigate light dark matter particles (, Talk presented CIPANP2015, 6 pages, 6 figures

Abstract

The large next generation liquid-scintillator detector LENA (Low Energy Neutrino Astronomy) offers an excellent opportunity for neutrino oscillometry. The characteristic spatial pattern of very low monoenergetic neutrino disappearance from artificial radioactive sources can be detected within the long length of detector. Sufficiently strong sources of more than 1 MCi activity can be produced at nuclear reactors. Oscillometry will provide a unique tool for precise determination of the mixing parameters for both active and sterile neutrinos within the broad mass region 0.01 - 2 (eV)^2. LENA can be considered as a versatile tool for a careful investigation of neutrino oscillations.

Abstract

PoS(EPS-HEP 2009)283 - The LAGUNA design study is financed by FP7 Research Infrastructure "Design Studies" Grant Agreement No. 212343 FP7-INFRA-2007-1.; International audience; A next generation European deep underground neutrino observatory is considered within the LAGUNA design study. Three detector options are presently considered: GLACIER liquid argon Time Projection Chamber; LENA liquid scintillator and MEMPHYS water Cherenkov. It will provide both: the high statistics measurement of neutrinos from variety of sources, and high sensitivity searches for matter instability. To accommodate such giant detectors a new underground laboratory is required. The LAGUNA design study considers the following seven candidate sites in Europe: Boulby (UK), Canfranc (Spain), Fréjus (France/Italy), Pyhäsalmi (Finland), Polkowice-Sieroszowice (Poland), Slanic (Romania) and Umbria (Italy). The three detection techniques and summary of the physics potential of proposed detectors are discussed in this short paper.

Abstract

Scintillators are employed for particle detection and identification using light-pulse shapes and light quenching factors. We developed a comprehensive model describing the light generation and quenching in CaWO$_4$ single crystals used for direct dark matter search. All observed particle-dependent light-emission characteristics can be explained quantitatively, light-quenching factors and light-pulse shapes are calculated on a microscopic basis. This model can be extended to other scintillators such as inorganic crystal scintillators, liquid noble gases or organic liquid scintillators.
