Abstract
Experiments have been designed and performed using the IR-MPF-100 dense plasma focus device (40 kV , 144 µF , 115 kJ) . In these experiments, the charging voltage of the capacitors is 14 kV, the pressure of the deuterium working gas is 1.5 mbar. These experiments are designed to detect the emitted neutrons and deuterons and to measure the energy of neutrons and deuterons. By placing a plastic scintillator detector 2.5 m away from the pinch area and measuring time of flight of neutrons, the neutron beam energy was measured in the range of 2 – 2.52 MeV. In order to measure the energy of the deuterons, an aluminum target is placed in front of the anode. When ions collide to the target, x-ray is emitted and the emitted x-ray is detected. Time interval between the anode X-ray (first signal) and the target X-ray (second signal) results deuterons time of flight (TOF). In this research, ions energy was measured in the range of 56 – 462 keV.
