Abstract

We present the magnetically shielded room (MSR) for the n2EDM experiment at the Paul Scherrer Institute which features an interior cubic volume with each side of length 2.92m, thus providing an accessible space of 25m3. The MSR has 87 openings up to 220mm diameter to operate the experimental apparatus inside, and an intermediate space between the layers for sensitive signal processing electronics. The characterization measurements show a remanent magnetic field in the central 1m3 below 100pT, and a field below 600pT in the entire inner volume, up to 4\,cm to the walls. The quasi-static shielding factor at 0.01\,Hz measured with a sinusoidal 2muT peak-to-peak signal is about 100,000 in all three spatial directions and rises fast with frequency to reach 10^8 above 1Hz., Comment: 10 pages, 15 Figures, submitted to Review of Scientific Instruments

109. Beta spectrum shape measurements using a multi-wire drift chamber and a plastic scintillator

Author

De Keukeleere, L., Rozpędzik, Dagmara, Bodek, Kazimierz, Severijns, N., Łojek, Konrad, Perkowski, Maciej, Vanlangendonck, S., and Hayen, L.

Abstract

Spectrum shape measurements in nuclear $\beta$ decay are a versatile observable. They can be used to test physics beyond the Standard Model with results being complementary to high energy collider experiments. In addition, the $\beta$ spectrum shape is a useful tool to probe Standard Model effects. One of those effects is called Weak Magnetism and is induced by QCD interactions between quarks in the nucleon. In order to study effects on the order of $10^{-3} - 10^{-2}$ in the $\beta$ spectrum shape, a new prototype spectrometer, named miniBETA, was designed and built. It consists of a 3D low-pressure gas tracker, i.e. a multi-wire drift chamber with hexagonal cells, and a plastic scintillator for triggering the data acquisition and recording the $\beta$ particle energy. Results of the miniBETA spectrometer characterization, supported by Monte Carlo simulations in Geant4 and Garfield++, are reported here. In addition, the preliminary results from $\beta$ spectrum shape measurements on the allowed Gamow-Teller transition $^{114}\textrm{In}\rightarrow ^{114}\textrm{Sn}$ are presented, including an extraction of the Weak Magnetism form factor.

Abstract

Muonic atoms have been used to extract the most accurate nuclear charge radii based on the detection of X-rays from the muonic cascades. Most stable and a few unstable isotopes have been investigated with muonic atom spectroscopy techniques. A new research project recently started at the Paul Scherrer Institut aims to extend the highresolution muonic atom spectroscopy for the precise determination of nuclear charge radii and other nuclear structure properties of radioactive isotopes. The challenge to combine the high-energy muon beam with small quantity of stopping mass is being addressed by developing the concept of stopping the muon in a high-density, a high-pressure hydrogen cell and subsequent transfer of the muon to the element of interest. Status and perspectives of the project will be presented.

Abstract

We present the design of a next-generation experiment, n2EDM, currently under construction at the ultracold neutron source at the Paul Scherrer Institute (PSI) with the aim of carrying out a high-precision search for an electric dipole moment of the neutron. The project builds on experience gained with the previous apparatus operated at PSI until 2017, and is expected to deliver an order of magnitude better sensitivity with provision for further substantial improvements. An overview is of the experimental method and setup is given, the sensitivity requirements for the apparatus are derived, and its technical design is described.

Abstract

We report on the design and first tests of a device allowing for measurement of ultracold neutrons polarisation by means of the simultaneous analysis of the two spin components. The device was developed in the framework of the neutron electric dipole moment experiment at the Paul Scherrer Institute. Individual parts and the entire newly built system have been characterised with ultracold neutrons. The gain in statistical sensitivity obtained with the simultaneous spin analyser is $(18.2\pm 6.1)$ % relative to the former sequential analyser under nominal running conditions.

Abstract

The hyperfine splitting of the 5g→4f transitions in muonic Re185,187 has been measured using high resolution high purity germanium detectors and compared to state-of-the-art atomic theoretical predictions. The spectroscopic quadrupole moment has been extracted using modern fitting procedures and compared to the values available in literature obtained from muonic x rays of natural rhenium. The extracted values of the nuclear spectroscopic quadrupole moment are 2.07(5) b and 1.94(5) b, respectively for Re185 and Re187.
