Fission chamber simulator for data acquisition performance tests

Divertor neutron flux monitor (DNFM) is a diagnostic system to be used for measurement of the total neutron yield and fusion power in the experimental fusion tokamak-reactor ITER. The diagnostic consists of the 18 fission chambers (FC), front-end electronics and data acquisition system to process, collect and archive data. The system should provide neutron flux measurements in dynamic range 7 orders of magnitude with a time resolution 1 ms and an error less 10%.
