AbstractA study of electrical properties and detection performances of the semi-insulating (SI) InP based detectors is presented. Detectors with a top P+ layer and a Schottky back contact give the charge collection efficiency about 90 % and an energy resolution 3.7% (FWHM) for 5.48MeV α-particles at 250 K. Detection of X-rays (122 keV and 60 keV) photons in temperature region 220–250 K is demonstrated. Multiple peaking observed during detection of photons is discussed.

Using computer programs Elmer FEM Solver for calculating electric fields and Geant4 for the passage simulation of particles through matter, calculations of charge collection efficiency for nuclear radiation matrix detector based on GaAs p-i-n diodes with different distances between pixels 110 microns and 50 microns were made. Based on data obtained detector structure optimization solution, which improves energy resolution, is proposed.

The results of experiments on the study of polarization phenomena and the charge collection efficiency in test structures of diamond ionizing radiation detectors using diamond plates of various types, including single-crystal NRNT-type, single-crystal CVD-type, as well as polycrystalline type, when exposed to alpha-radiation with an energy of 5.5 MeV are presented. Studies have demonstrated the existence of a number of problems with the device quality of diamond plates that affect the performance of spec-trometric-type detectors.
