摘要
In the present research, time-resolved of X-ray signals are investigated in a 4 kJ PF device using five filtered PIN-diodes and a Scintillation detector. At applied voltage 12 kV using nitrogen (N-2) gas, the optimum pressures for maximum yield of HXR and SXR emission were 3 torr and 4 torr respectively. At each operating pressure, multiple pulses in SXR signals with respect to amplitude and duration of emission were studied in a time span of 700-800 ns. According to energy response of filters used, the origin of X-ray pulses and also the approximate energy of X-ray photons were analyzed. It was found that at higher pressure 4 torr, the yield of SXR photons in different pulses increases 20-30% in comparison with the results obtained at pressure 3 torr while the yield of HXR decreases. The results confirm that the operating pressure is an effective parameter on the yield of SXR and HXR emitted from this device.
