摘要：

The detection of primary scintillation light in combination with the charge or secondary scintillation signals is an efficient technique in determining the events "t = 0" as well as particle photon separation in large mass TPC detectors filled with noble gases and/or condensed noble gases. The aim of this work is to demonstrate that costly photo-multipliers could be replaced by cheap novel photosensitive gaseous detectors: wire counters, GEMs or glass capillary plates coupled wish CsI photocathodes. We have performed systematic measurements with Ar, Kr And Xe gases at pressures in the range of 1-50 atm as well as some preliminary measurements with liquid Xe and liquid Ar. With the gaseous detectors we have succeeded in detecting a scintillation light produced by 22 KeV X-rays with an efficiency close to 100%. We also detected the scintillation light produced by beta's (5 keV deposit energy) with an efficiency close to 25%. Successful detection of scintillation from 22 keV X-rays open new experimental possibilities not only for nTOF and ICARUS experiments, but also in others, such as WIMP's search through nuclear recoil emission.
