Abstract
The National Ignition Facility requires a radiation-hardened, megapixel CMOS imaging sensor-based camera to be a direct physical and operational replacement for the CCD cameras currently used in x-ray streak cameras and gated imaging detectors. Camera electronics were selected to operate up to 10 krad(Si). The camera incorporates a fast dump of the sensor followed by exposure and image readout. This allows the dumping of charge due to the prompt radiation background and then readout of the longer persistence phosphor image from the x-ray diagnostics. Internal timing delays and optical performance were measured for a radiation-tolerant camera, based on the 2k by 2k CMV4000 sensor from CMOSIS Inc.
