A PULSED INTENSE X-RAY SOURCE BASED ON REP-RATE MARX GENERATOR
A repetitive pulsed intense X ray source operating in 1 ～ 2Hz is described briefly. It is utilized the technology of repetitive plasma opening switch(RPOS) and Inductance Energy Storage. After RPOS opening swiftly, a high voltage pulse reaching ～ 3MV is imposed on the bremsstrahlung radiating source diode and produced a intense X ray pulse. The X ray pulse parameters as following: peak dose rate is 0.25MGy/s at 0 5m, average dose rate is 0.15kGy/h at 1m, full width of half magnitude is ～100ns. The configuration, priciple and preliminary results are given in this paper.
