Abstract:
Hard x-ray emission by the bremsstrahlung is an important subject in Dense Plasma Focus device. Finding method to increase the emitted hard x-ray is interesting in Dense Plasma Focus operation. In this paper, we have studied hard x-ray emission by using low energy Dense Plasma Focus in different pressures for a copper anode with a diameter of 15mm. The high purity nitrogen is used as a working gas. The optimum pressure that attains the maximum intensity is belonged to 0.6 torr. For the first time we used wavelet transform to characterize time-frequency activity of hard x-ray emission in various pressures in DPF. The results show that time-frequency activity of hard x-ray intensities enhance at upper pressures, and maximum activity is at 0.6 torr
