Notes:
A Bragg crystal spectrometer, utilizing a microchannel plate coupled to optical film as the detection medium, has been constructed for use in soft x-ray spectroscopy. The sensitivity of this intensified gated camera to x-rays has been compared directly with standard x-ray film using a calibrated x-ray source. In addition, this high gain, intensified crystal spectrograph (ICS) has been used in an experiment to precisely measure spectral coincidences between x-ray lines in laser-generated plasmas, thus identifying candidates for photoresonant x-ray lasing schemes in the 10–21-A(ring) region. At long wavelengths the ICS was able to obtain useful data on faint lines in a single laser shot, rather than the multiple shots required by an adjacent spectrograph using x-ray film. It also allowed line coincidences to be verified by a new technique utilizing split disk targets. The design and construction of the ICS and results obtained with it are compared with those obtained with standard x-ray film.
