Initial development of X-ray diodes with transmission photocathode

摘要: 基于透射式阴极发射模型和平响应 XRD 原理,设计了透射式阴极,并制作550 nm CH+50 nm Au 的阴极,并在神光Ⅲ原型装置上开展了初步验证实验。首先利用反射式 XRD 施加负偏压的实验开展直穿光影响评估,施加偏压为-1500 V 时,没有观测到探测信号,表明直穿光产生光电子得到了有效抑制。利用原型主激光与第九路激光打靶实验,施加负偏压的透射式 XRD 获得探测信号显示第二个峰值信号延后第一个信号3.01 ns,该结果与第九路激光延迟时间一致,时间分辨能力满足实验要求。

Abstract: Based on emission mode of transmit cathode and the principle of FXRD,a transmit cathode for XRD was de-signed and manufactured.A sample with a cathode made up of 550 nm CH and 50 nm Au was used for preliminary experiments on SG-Ⅲ prototype facility.Firstly the influence of direct X-ray was evaluated using an XRD with reflective cathode.The results show that the XRD with -1 500 V bias voltage could eliminate the influence of X-ray arrived at the anode for XRD with transmis-sion cathode.Then when main lasers and the ninth laser were operating on SG-Ⅲ prototype facility,the transmission cathode XRD with negative bias voltage captured normal signals.The results show that the second peak signal delay 3.01 ns by the first peak,which is in accord with the time sequence of main lasers and the ninth laser.The capability of temporal resolution can satis-fy requirements of experiments.
