Pulse neutron measurement of dense plasma focus device based on scintillation detector
摘要
Abstract
A scintillator detector for monitoring dense plasma focus(DPF)device neutron yield and waveform was developed.The size parameters of the scintillator were determined by simulating the curve of the variation of the photons emitted by the scintillator with the thickness,and the sensitivity of the detector was obtained by relative calibration.The scattering distribution in the experimental environment was simulated according to the Monte-Carlo method,and the experimental layout was designed according to factors such as the linear range of the probe.The D-D pulse neutron yield and time waveform of the self-developed DPF device were measured using the developed scintillator detector,and the measurement results were analyzed and discussed.The test results indicate that the scintillation detector has detected the hard X-rays and neutron waveforms generated by the DPF device.The time difference between their peak signals matches the flight time of 2.45 MeV neutrons,with a neutron pulse width of about hundreds of nanoseconds.关键词
