利用金刚石探测器测量软X光辐射功率

MEASUREMENT OF SOFT X-RAY POWER WITH A DIAMOND DETECTOR

使用天然Ⅱａ型金刚石光电导探测器（ＰＣＤ），测量激光等离子体发射的软Ｘ光辐射。由于探测器在２００ｅＶ～２２００ｅＶ之间具有平响应特性，可以不加滤片直接测量Ｘ光功率和能量。金刚石ＰＣＤ与软Ｘ光能谱仪和平响应Ｘ光二级管的测量结果基本一致。

hotoconductive detectors (PCDs) fabricated from natural Ⅱa diamond had been uased to measure the X-ray radiation emitted from laser-produced plasmas. The detectors were operated without any absorbing filters because of their flat-response between 200eV and 2200eV. Excellent agreement was achieved between a diamond PCD and a Soft X-ray energy spectrometer (or a flat-response XRD)
