Abstract

The invention discloses a wide dynamic range neutron flux measuring system and method based on a Pulse-Current mode. The system comprises a fission chamber, a reference chamber, a Pulse module, a Current module, a postprocessing module and a mode selection mode. The invention further discloses a wide dynamic range neutron flux measuring method based on the Pulse-Current mode. According to the system and method, the contradiction between background radial inhibition capacity and the requirement for the signal to noise ratio in a traditional wide dynamic range neutron flux measuring process is eliminated.

Description

technical field [0001] The invention relates to the field of nuclear detection, in particular to a wide dynamic range neutron flux measurement system and method based on Pulse-Current mode. Background technique [0002] Fission chamber detectors are widely used in the field of neutron flux monitoring because of their good gamma suppression ability. neutrons and fissile material in the fission chamber (e.g. 235 U) Fission fragments will be produced when interacting, and the fragments will cause gas ionization during the indoor drift process to output a pulse signal. When the neutron flux is low, the accumulation probability of the pulse signal output by the fission chamber is very small, and the neutron flux can be obtained by counting the pulses. This working mode is called Pulse mode; as the neutron flux increases , the output pulses of the detector begin to accumulate, and the Pulse mode will not be able to obtain the correct flux value. At this time, the Campbell mode c...
