X-ray radiation of the plasma focus with inverse pinch switch

X-ray radiation characteristics of the plasma focus with inverse pinch switch was investigated. The plasma focus device power with capability of 20 kJ contains a 40 kV condenser power supply and adopts a new type of switch system, The mechanism of X-ray radiation was analyzed using a pair of detectors. The variation of X-ray radiation as a function of the position of emitted X-ray and the shape of electrode was examined closely using the time-integrated method. By analyzing the mechanism, we found that the X-ray radiation has three peaks in the optimal plasma focus condition with the middle one being m = 0 instability.
