Noble-gas operation, timing and imaging properties of Thick Gaseous Electron Multiplier (THGEM)-based radiation detectors

 Keywords:

  • Charge transport and multiplication in gas
  • Electron multipliers (gas)
  • Gaseous detectors

 Abstract:
This work presents the investigations of some properties of the Thick Gaseous Electron Multiplier (THGEM). It is a novel multiplier concept, developed at the Radiation Detector Physics Laboratory at WIS, in which avalanche multiplication occurs within millimeter-scale diameter holes drilled over the surface of a thin, flat insulator. This work concentrates on the following experimental and simulation studies: time resolution with UV photons and relativistic particles, imaging properties with soft x-rays and preliminary ones with fast neutrons as well as operation in pure noble gases. While the first studies are relevant to numerous general radiation detection applications, the latter relate to their possible incorporation in Dark Matter, double Beta-decay and Neutrino detectors and in noble-liquid Gamma-Cameras.
