Description
We have investigated the possibility of using a liquid Xe (LXe) detector for combined imaging and spectroscopy of neutrons and gamma-rays in the MeV range. This activity is part of the R&D work on LXe detectors performed at WIS for the search of dark matter.
Our aim is a detection of hidden explosives and fissile materials in cargo and containers using fast neutrons resonant transmission radiography and high energy dual discrete gamma-ray radiography. The detector consists of a fast liquid-xenon (LXe) converter-scintillator coupled to a UV-sensitive gaseous imaging photomultiplier (GPM) made of a cascaded Thick-Gas Electron Multipliers (THGEMs) of which the first one is coated with a CsI photocathode.
Simulation study and experimental results of the GPM performance in combination with a LXe converter will be presented and the cryogenic experimental system for radiographic investigations with neutrons and gammas will be described.
