Electrons photoproduced by UV-photons on a CsI photocathode, or deposited by ionizing particles and ultrasoft X-rays in low-pressure gas media, are efficiently detected in Low Pressure Multistep Avalanche Electron Multipliers. A Solid Photocathode Avalanche Chamber (SPAC) Imaging Photomultiplier was coupled to a Xe-filled Gas Scintillation Detector. Its performance when exposed to 60 KeV X-rays is presented. This paper discusses stability of the CsI photocarthode in detail. The latest experimental results from Primary Ionization Cluster Counting of charged particles and ultrasoft X-rays are presented. UV laser-induced ionization and Monte-Carlo simulations are used to study the processes involved.
