Data-Acquisition System of a Multidetector Device with Tagged Neutrons with Parallel Transmission of Events

— The principles of the layout and operation of data-acquisition electronics for tagged neutron technology are described. They are based on the selection of useful events according to specified criteria with data acquisition by a buffer memory unit and subsequent transfer of data arrays to a remote computer for processing and visualization. The main selection criterion is the presence of signals from the α and γ detectors in specified time intervals and amplitude ranges in the absence of overlapping events. By using a backbone−modular architecture, it is possible to carry out parallel signal processing and data transmission at several levels, which allows connection of almost any number of γ detectors without losing measurement accuracy and data integrity. A model of the setup has been produced for testing the developed equipment, and experiments were conducted to study its characteristics. The experimentally achieved data-transfer rate (for α−γ coincidences) is 3 × 10 5 s −1 , which is several times higher than the maximum transfer rate of existing data-acquisition systems for the tagged neutron technology.
