摘要：

This paper presents the results of measurements of fission fragments using a time-of-flight system with a position-sensitive detector based on microchannel plates designed to measure the masses of nuclear reaction products at the MAVR facility. The advantage of such MCPs is their high positional sensitivity and high efficiency of registration of heavy charged particles with low energy. The paper presents a technical description of the fission fragments registration system and the results of measuring the parameters of a position-sensitive detector based on large-area microchannel plates (40 x 60 mm(2)) obtained by measuring Cf-252 spontaneous fission fragments. The coordinate resolution along the X and Y axes was determined when fission fragments were registered in the N-14+Au-192 reaction at the MAVR installation. The time resolution of the PSD was obtained by registering the time of flight of alpha particles emitted by the radioactive source Ra-226.
