The experimental effort to detect neutrinoless beta decay has shown numerous R&D advancements in the past several years. One of the R&D lines being explored in NEXT and presented in this talk is that of digitizing tracking information with a fast optical camera. This would enable a novel direction in the search for neutrinoless double beta decay within the NEXT collaboration: demonstrating a...
The next generation of neutrinoless double beta decay searches aims to reach sensitivities in the half-life of the process up to $10^{28}$ years. This will require tonne scale detectors with essentially no background in their region of interest. One of the most promising solutions, which may be implemented by gas or liquid xenon TPCs, is the possibility of tagging the daughter ion produced in...
HeRALD, the Helium Roton Apparatus for Light Dark Matter, will use a superfluid 4He target to study the sub-GeV dark matter parameter space. The HeRALD design is sensitive to all signal channels produced by nuclear recoils in superfluid helium: singlet and triplet excimers, as well as phonon-like excitations of the superfluid medium. Excimers are detected via calorimetry in and around the...
Project 8 aims to measure neutrino mass by detecting radiation from single electrons. The operating principle is to observe tritium beta decay in a uniform magnetic field, which causes the emitted electron undergo cyclotron motion and radiate. Measuring the radiation frequency yields the electron's energy spectrum, which in turn encodes the neutrino mass. For the current R&D phase, the...
We describe the fabrication and characterization of semi-insulating GaN devices for the detection of ionizing radiation with applications in high radiation environment. We present the DC characterization and the signal response from Am-241 α-source of such device. The detector prototypes show up to 80% charge collection efficiency with bias voltages as low as -40V. Wide band gap semiconductors...
