Abstract

The x-ray streak camera and x-ray framing camera for the National Ignition Facility were redesigned to improve electromagnetic pulse hardening, protect high voltage circuits from pressure transients, and maximize the use of common parts and operational software. Both instruments use the same PC104 based controller, interface, power supply, charge coupled device camera, protective hermetically sealed housing, and mechanical interfaces. Communication is over fiber optics with identical facility hardware for both instruments. Each has three triggers that can be either fiber optic or coax. High voltage protection consists of a vacuum sensor to enable the high voltage and pulsed microchannel plate phosphor voltage. In the streak camera, the high voltage is removed after the sweep. Both rely on the hardened aluminum box and a custom power supply to reduce electromagnetic pulse/electromagnetic interference (EMP/EMI) getting into the electronics. In addition, the streak camera has an EMP/EMI shield enclosing the front of the streak tube.

摘要

国家点火装置的X射线条纹相机和X射线分幅相机进行了重新设计，以增强电磁脉冲硬化能力，保护高压电路免受压力瞬变影响，并最大限度地利用通用部件和操作软件。这两种仪器都使用相同的基于PC104的控制器、接口、电源、电荷耦合器件相机、保护性气密外壳和机械接口。通过光纤与两种仪器相同的设施硬件进行通信。每种仪器都有三个触发器，既可以是光纤的，也可以是同轴的。高压保护包括一个真空传感器，用于启用高压和脉冲微通道板磷光体电压。在条纹相机中，扫描结束后会移除高压。两者都依靠硬化铝箱和定制电源来减少进入电子设备的电磁脉冲/电磁干扰（EMP/EMI）。此外，条纹相机还有一个EMP/EMI屏蔽罩，包围着条纹管的前端。
