摘要

The spectra of neutrons outside the plasma focus device PF-1000 with an upper energy limit of ≈1 MJ was measured using a Bonner spheres spectrometer in which the active detector of thermal neutrons was replaced by nine thermoluminescent chips. As an a priori spectrum for the unfolding procedure, the spectrum calculated by means of the Monte Carlo method with a simplified model of the discharge chamber was selected. Differences between unfolded and calculated spectra are discussed with respect to properties of the discharge vessel and the laboratory layout. © 2010 American Institute of Physics Article Outline INTRODUCTION EXPERIMENTAL ARRANGEMENT Plasma focus device Monitors of neutron yield Bonner spheres spectrometer Thermoluminescent detectors ANALYSIS RESULTS AND DISCUSSION CONCLUSION
