A mu mu ampere current source capable of simulating the current generator characteristics of an ion chamber was developed for a device and/or method of verifying the current linearity and frequency response of high impedance power channels. The apparatus consists of a multiplier photo-tube excited by a variable intensity light source. The unit is portable and easily T'd into power channels at the ion chamber for use in the field calibration tests. (W. D.M.)
