Almost the entire complex of spectrometers of the IBR-2M reactor is equipped with MPD data acquisition electronics developed at FLNP and designed for processing and accumulating data from an array of point neutron detectors. In accordance with the plans for the development of spectrometers, with an increase in the number of detector channels and neutron flux, increased requirements are placed on data acquisition systems. Currently, FLNP is developing and debugging a new data acquisition system based on MPD-32 blocks. However, due to the shutdown of the reactor for a long period, full tests of the MPD-32 system on spectrometers are impossible.

The aim of this work was to develop a test bench with a simulator of reactor signals, choppers, and detectors for the data acquisition system on the HRFD spectrometer of the IBR-2M reactor. Such a system will allow testing and complex debugging of the data collection system in laboratory conditions. The test bench provides generation of signals of a multichannel detector system with simulation of a typical time-of-flight spectrum of thermal neutrons at HRFD, FSD and other facilities. To estimate the maximum data acquisition rate of the MPD-32 system, the stand provides simulation of controlled flux intensity for 32 detector signals and neutron chopper signals.
