Abstract

X-ray spectra from laser fusion targets are normally measured with flat crystal (nonfocusing) spectrographs. We describe here the characteristics of a focusing spectrograph which is capable of recording wide band spectra with significantly higher sensitivity. Measuring spectra in the (10-11) A range from glass microballoons imploded by a two-beam Nd:Glass laser system we find intensity per unit area on film about 100 times higher with a curved mica than with a flat mica spectrograph.

摘要

激光聚变靶的X射线光谱通常用平面晶体（非聚焦）光谱仪进行测量。我们在此描述一种聚焦光谱仪的特性，它能够以显著更高的灵敏度记录宽带光谱。在用两束钕玻璃激光系统内爆的玻璃微球测量（10 - 11）埃范围内的光谱时，我们发现，使用弯曲云母片时胶片上单位面积的强度比使用平面云母光谱仪时高约100倍。
