Abstract

A variety of soft X-ray diagnostics are being fielded on the Los Alamos National Laboratory Pegasus and Procyon pulsed power systems and also being fielded on joint US/Russian magnetized target fusion experiments known as MAGO (Magnitoye Obzhatiye). We have designed a low-cost modular photoemissive detector designated the XRD-96 that uses commercial 1100 series aluminum for the photocathode. In addition to photocathode detectors a number of designs using solid state silicon photodiodes have been designed and fielded. We also present a soft X-ray time-integrated pinhole camera system that uses standard type TMAX-400 photographic film that obviates the need for expensive and no longer produced zero-overcoat soft X-ray emulsion film. In a typical experiment the desired spectral energy cuts, signal intensity levels, and desired field of view will determine diagnostic geometry and X-ray filters selected. We have developed several computer codes to assist in the diagnostic design process and data deconvolution. Examples of the diagnostic design process and data analysis for a typical pulsed power experiment are presented.

脉冲功率机器的软x射线诊断

各种软x射线诊断正在洛斯阿拉莫斯国家实验室Pegasus和Procyon脉冲功率系统上部署，也正在美国/俄罗斯联合磁化目标聚变实验MAGO (Magnitoye Obzhatiye)上部署。我们设计了一种低成本的模块化光电探测器，命名为XRD-96，使用商用1100系列铝作为光电阴极。除了光电阴极探测器之外，许多使用固态硅光电二极管的设计已经被设计和应用。我们还提出了一种软x射线时间集成针孔相机系统，该系统使用标准型TMAX-400摄影胶片，避免了对昂贵且不再生产的零涂层软x射线乳剂胶片的需要。在一个典型的实验中，所需的光谱能量切割、信号强度水平和所需的视场将决定诊断几何形状和所选择的x射线滤光片。我们已经开发了几个计算机代码，以协助诊断设计过程和数据反卷积。介绍了典型脉冲功率实验的诊断设计过程和数据分析实例。
