On the basis of experimental studies the surface-barrier technology for fabrication of sectional nuclear radiation detectors with using of the high-resistance n-Si plates of large diameter (~ 100 mm) was optimized. The 9-sectional detector matrixes were manufactured. In such matrix each section is a separate detector with the thickness of sensitive area W ≤ 350 μm, the working area S = 4 cm², and the energy resolution R = 50…75 keV under irradiation by three-component α-source. The electrophysical and spectrometric characteristics of the sectional silicon detectors were determined. The manufactured detectors can be used in the nuclear experiments involving heavy ions at the low yields of reaction products.
