摘要
The temporal and spatial characteristics of the x-ray emission in a 3 kJ plasma focus are investigated when operating in H(2) with an Ar admixture. The experiments are performed in a UNU/ICTP PFF device. The x-ray emission is detected with a multichannel system of PIN-Si diodes with different filtering looking axially and radially into the focusing region. Two main periods are observed in the x-ray emission, corresponding to two successive compressions in the focus. X-ray emission arising from electron beam activity and dense plasmas is identified. On the basis of the x-ray emission characteristics several features of the plasma focus dynamics are discussed.
