Advances in Cryogenic Avalanche Detectors
Cryogenic Avalanche Detectors (CRADs) are referred to as a new class of
noble-gas detectors operated at cryogenic temperatures with electron
avalanching performed directly in the detection medium, the latter being in
gaseous, liquid or two-phase (liquid-gas) state. Electron avalanching is
provided by Micro-Pattern Gas Detector (MPGD) multipliers, in particular GEMs
and THGEMs, operated at cryogenic temperatures in dense noble gases. The final
goal for this kind of detectors is the development of large-volume detectors of
ultimate sensitivity for rare-event experiments and medical applications, such
as coherent neutrino-nucleus scattering, direct dark matter search,
astrophysical (solar and supernova) neutrino detection experiments and Positron
Emission Tomography technique. This review is the first attempt to summarize
the results on CRAD performances obtained by different groups. A brief overview
of the available CRAD concepts is also given and the most remarkable CRAD
physics effects are discussed.Comment: 60 pages, 58 figures. Invited talk at MPGD2011 Conference, Aug 29 -
