New investigations of the porous dielectric detectors
Abstract
The results of the study of the multiwire porous dielectric detector and microstrip porous dielectric detector filled with porous CsI are presented. Detectors were exposed to \alpha -particles with energy of 5.46 MeV and X-rays with energy of 5.9 keV and operated with a constant applied voltage. It is found that right after thermal deposition of the porous CsI layer the detector's performance is unstable, it has poor spatial resolution. However in a course of time the performance becomes stable and it acquires high spatial resolution.
