Paper Abstract

As applications are forthcoing in gated image intensifier tubes the selection of the output screens phosphor or these uses becomes less routne The c!assc P-20 green phosphor has some peculiarities that niust be reckoned with in nonCW modes such as a long-term decay tail and a rather slow rise time, At the other extreme is the rare-earth P-6 also green and its cousin, the P-47 (blue), with rise and fail times in the nanosecond range Ethciencies are ower..only about 20% ot the P-20's but. this can usually be compensated by increasing overall gain by other means The integrating time of the ultimate readout device (often CCL's, ton example) may determine the most approprIate phoerhor Data will be presented to aid the systen designer in selecting a phosphor
