It was early recognized that the magnitude of the discharge current in this assembly is an important parameter and several current-measuring devices were built. In addition, methods were developed for checking the calibration of these current-measuring devices in the required range of 20 - 100 kiloamperes at 17 megacycles. For current measurement, solenoidal and toroidal coils were used, and they were calibrated against either a two-turn coil or a shunt. Good agreement was obtained among the current values indicated by the various currentmeasuring coils and by the two calibrating devices. In the report, the various coils and the shunt are described and a summary of the results is given.
