The multiwire porous detector consists of anode wires, an Al cathode and a gap between them filled with porous CsI. The microstrip porous detector consists of an insulating plate covered with metallic strips, micromesh cathode and a gap between them filled with porous CsI. For some time after being manufactured, these detectors' performances are non-stable and they have poor spatial resolution. However, after being kept in vacuum for a certain time, they spontaneously acquire stability and spatial resolution better than 100$μ$m and have detection efficiencies of 100% and 70% for heavily ionizing $α$-particles and 5.9 keV X-rays respectively. The MWPDD performs stably at an intensity of heavily ionizing $α$ -particles of 711cm$^{-2}$s$^{-1}$.18 pages, 17 pictures, PDFInstrumentation and Detectorstext
