Abstract

Abstract

Two fission chambers with different amounts of fissile material (enriched 90% uranium-235) have been manufactured for neutron flux detection in a thermonuclear fusion device. The characteristics of neutron signal and its discrimination from other signals, and a plateau of high voltage between the anode and cathode have been validated in a thermal neutron source. The energy responses of the two fission chambers at seven energy levels have been calibrated in an accelerator fast neutron source and the results agree well with the simulations.
- fission chamber,
- fusion neutron flux,
