Single electron sensitive GridPix TPCs and their application in Dark Matter search and v-less Double Beta Decay Experiments [PDF]

Journal of Physics: Conference Series, 2011
The industrial production of monolithic GridPix pixel chips for the digital readout of primary electrons in a TPC is under study at IZM-Fraunhofer, Berlin. With future low-cost chips, new applications are foreseen in TPCs for bi-phase Ar/Xe dark matter experiments, and for v-less double beta decay experiments.

ZnWO_4 crystals as detectors for double beta decay and dark matter experiments

, 2004
Energy resolution, alpha/beta ratio, and the pulse shape discrimination ability of the ZnWO_4 crystal scintillators were studied. The radioactive contamination of a ZnWO_4 crystal was investigated in the Solotvina Underground Laboratory. Possibilities to apply ZnWO_4 crystals for the dark matter and double beta decay searches are discussed.

Sensitivity to neutrinoless double beta decay of Xe-136 with a third generation TPC dark matter experiment

, 2022
A third-generation (G3) two-phase liquid xenon TPC will not only be able to explore new regions of parameter space of dark matter, but also competitively search for some neutrino processes of interest, such as neutrinoless double beta decay (DBD). In this work we will show that a G3 detector, with up to one hundred tonnes of natural xenon mass and ...

Improved axion haloscope search analysis

Journal of High Energy Physics, 2021
One of the most significant and practical figures of merit in axion haloscope searches is the scanning rate, because of the unknown axion mass. Under the best experimental parameters, the only way to improve the figure of merit is to increase the ...

Demonstration of the event identification capabilities of the NEXT-White detector

Journal of High Energy Physics, 2019
In experiments searching for neutrinoless double-beta decay, the possibility of identifying the two emitted electrons is a powerful tool in rejecting background events and therefore improving the overall sensitivity of the experiment.
