Abstract

Time- resolved spectrum of the neutrons emitted from PLASMA FOCUS devices is a very important piece of information for description of neutron generation mechanism in these devices. In the last two decades, some methods were presented to evaluate this spectrum from the signals of various neutron detectors placed at different distances from the device. All of these procedures are based on the time of flight analysis method, the time- resolved neutron spectrum is derived from solving the INTEGRAL EQUATION which relates the velocity spectrum of neutrons to time- resolved neutron flux. But the solution of this equation is very complicated and each of presented methods has deficiencies. In this paper a new method is presented on the base of wavelet analysis for solution of this equation to derive the TIME- RESOLVED ENERGY SPECTRUM. This method is more efficient than the previous ones in different aspects. Using this method for analyzing the results of Poseidon PLASMA FOCUS device (780 kJ, 100 kV), it is observed that its results for neutron energy spectrum and the average energy of neutrons are acceptable.
