Abstract

One of the important building blocks on Qiangguang-I accelerator is the short-pulse high dose rate gamma-ray source, which is mainly used to generate short pulse intense bremsstrahlung. The process of generating high dose rate gamma-ray with about 20 ns pulse duration on Qiangguang-I accelerator was introduced. The insulating characteristics of insulator and MITL of short-pulse high-impedance intense electron beam diode were analyzed. The characterization of plasma opening switch (POS) was presented. The design approach for diode operating parameters including the diode impedance, cathode and anode was described. The experimental results show that the pulse duration of bremsstrahlung is about 20 ns, and the dose rates at areas of 2, 30 and 100 cm² are 10¹¹, 0.7 × 10¹¹ and 10¹⁰ Gy/s respectively.
