摘要
在ICF实验研究中,我们应用新研制的经快中子辐照处理过的GaAs晶体材料做成的光导电探测器首次实验观察到各种结构的内爆靶发射的硬X光时间波形信号以及硬X光的空间角分布。这种探测器对X光有很高的灵敏度(约10^(-18)C/keV),有快的响应(约100ps),具有抗干扰能力强,灵敏度高体积小,用于ICF实验的X光诊断有独特优点。
In the ICF experiments, we have applied newly developed small GaAs - photoconductor detectors made with neutron -treated GaAs crystal material. Hard X -ray signals and hard X-ray angular distribution have been obtained with the detectors. The sensitivety to the X rays is about 10-18C/keV and the response about 100ps. The detectors have the ability against electromagnitic radiation inferfere in the target chamber.
