Abstract:The results of investigation of special strip and pixel detectors are presented. The possibility to achieve the internal amplification mode similar to proportional gas counters in a pixel detector made from n-type silicon is shown. An "amplified" peak at the energy 70 MeV with the energy resolution FWHM ~10 MeV is visible on the α-spectrum of 238 Pu (E α = 5.5 MeV). The real internal amplification effect (with a gain of 20) has been demonstrated with the detectors made from p-silicon. In this case, the detecto… Show more
