Charge-injection devices (CIDs) are being used to image x rays in laser-fusion experiments on the University of Rochester’s OMEGA Laser System. The CID cameras are routinely used up to the maximum neutron yields generated (~10^14 DT). The detectors are deployed in x-ray pinhole cameras and Kirkpatrick–Baez microscopes. The neutron fluences ranged from ~10^7 to ~10^9 neutrons/cm^2 and useful x-ray images were obtained even at the highest fluences. It is intended to use CID cameras at the National Ignition Facility (NIF) as a supporting means of recording x-ray images. The results of this work predict that x-ray images should be obtainable on the NIF at yields up to ~10^15, depending on distance and shielding.
