Abstract
We have used two types of MOS detector arrays to sense directly patterns of soft x-rays, in the Lawrence Livermore Laboratory experimental laser-fusion program. A linear self-scanning photodiode array CSSPA) is used in a wave-length-dispersive spectrometer. A frame transfer charge-coupled device (CCD) facilitates the use of an x-ray microscope. Measurements and calculations of the x-ray sensitivity of these devices will be presented. Their linearity and dynamic range will be discussed, as well as data recovery systems for each detector. We will describe our experiences in using these devices to detect pulses of x-rays in laser-fusion experiments.
