The work is devoted to the development and testing of silicon detectors and readout electronics for them to measure p+B 11 reaction cross section at the Prometeus proton accelerator complex. This reaction is being actively studied as a possible tool for a binary technology for the treatment of oncological diseases [1]. The products of being absorbed by the target, they significantly increase the local energy release, relative to the energy release of a single proton. To measure the cross section of this reaction in the energy range corresponding to the Braga peak, the authors created silicon detectors with an effective area of 1 cm 2 with a charge-sensitive preamplifier, readout electronics, and a software package for data analysis. The silicon detector is optimally suited for solving problems of this type, since it simultaneously has sufficient energy resolution and a suficient sensitive surface area. At present, individual elements of the system are being tested at the Prometheus accelerator complex (using the proton-boron reaction) and the HELIS ion accelerator (using the d+d reaction). At the HELIS facility, the results obtained are consistent with measurements made by a diamond detector [2] (Fig.1). The obtained results testify to the readability of the read path.
