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. The first phase is a radiation-tolerant camera for characterization of radiation effects on the imaging sensor. This will be followed by a fully hardened version. The radiation-tolerant camera, based on the 2k by 2k CMV4000 sensor from CMOSIS Inc., has been built and optical performance was measured. Camera parts were selected to operate up to 10 krad(Si) and the camera incorporates a fast charge and dump of the sensor pixels, followed by image readout. This allows the dumping of charge due to the prompt radiation noise and then readout of the longer persistence phosphor signal from the x-ray diagnostics.
