Time Dependent Behavior of Neutron Emission in Dena Plasma Focus

The paper reports on some experimental studies carried out on Dena plasma focus (25 kV, 288 μF, 90 kJ) device with the deuterium filling gas. Time dependent neutron energy spectrum for each discharge, is obtained using an extended time of flight method by five fast neutron scintillators detectors. Temporal change of the neutron emission and the related pinch phases are found and discussed.
