%X The high and low density sandwich CsI photocathodes have been developed and optimized to yield relatively stable and effecient systems for photon detecting in the 0.1-10 keV region. For sandwich CsI photocathodes, the photon detecting effeciency is 2-10 times higher than that oh-tained with the high density Csl photocathodes in the 0.1-10 keV region. The energy distributions of the photoemitted secondary electrons have been measured to be similar for the high density sandwich photocathodes and with about 2eV full-width-half-maximum. The high efficiencies and relatively narrow emitted electron energy distributions have made the CsI transmission photocathodes extensively useful in soft x-ray detectors and counters especially is x-ray streak camera applications.
