BINPTwo-phase Cryogenic Avalanche Detector
(CRAD) with EL gap and THGEM/GAPD-matrix
multiplier concept and experimental setup

• Concept Detector of nuclear recoils of ultimate
  sensitivity for Coherent Neutrino-Nucleus
  Scattering and Dark Matter Search experiments
• Principle Combining THGEM/GAPD-matrix multiplier
  with PMT readout of proportional EL of the
  ionization (S2) signal, in single-electron
  counting mode JINST 5 (2010) P08002

BINP Recent results on two-phase Cryogenic
Avalanche Detector (CRAD) performance with THGEM
multiplier
1. Two-phase CRAD in Ar with combined
THGEM/GAPD-matrix multiplier. Spatial resolution
is far superior compared to that of PMTs NIM A
732 (2013) 213
2. First measurement of ionization yield of
nuclear recoils in liquid Ar using two-phase CRAD
with THGEM charge readout and DD neutron
generator, for energy calibration of dark matter
search detectors EPL 108 (2014) 12001
3. First systematic study of proportional
electroluminescence in two-phase Ar using
two-phase CRAD with EL gap and THGEM/GAPD-matrix
multiplier, for dark matter search and coherent
neutrino-nucleus scattering experiments
