Operation of Vidicons in Unusual Environmental Conditions
The influence of unusual environmental conditions on the performance of commercially available vidicons is reported. It is found that increasing the faceplate temperature to 90 C does not affect the resolution, increases the dark current and decreases the sensitivity when the dark current is held constant. Data are presented for the durations of application of greater than normal cathode radiation at which image burn is produced, It is found that the envelopes of most commercial types of vidicons do not fail at pressures below 50 atmospheres. The only observed effect of nuclear radiation was the reduction of sensitivity caused by browning of the glass faceplate.
