Paper Abstract

The miniature soft X-ray detector (M-XRD) is the key part of the miniature soft X-ray spectrometer, which was developed and used in laser-produced plasma interaction experiments on Shenguang III Laser Facility. The results of the analyze shown that the significant schemes was to get well-proportioned electric field distributions, which can obtain the strongest intensity of electric field, by using the ultra-broad band air transmission line to transmit the signal to the measure port in less aberration. Adopting the finite element theory, the simulation of the X-ray detecting diode and the design of ultra-broad band air coaxial transmission line by HFSS has been carried out. Compared with the traditional XRD, the size of M-XRD reduced to 1/3. The experimental results indicated that the response time was excelled to the traditional XRD and the response time was less than 80 ps.
