Measurements of High Voltage across the Vacuum Diode of a High-Current Generator by Using Photoneutron Reactions

摘要

A new method is proposed for measuring the voltage across the vacuum diode of a high-current generator by determining the high-energy edge of bremsstrahlung from an electron beam with the help of photoneutron reactions. The method is approved in the RS-20 facility with a plasma opening switch in the voltage range 2.5/4.5 MV. The results obtained by using this technique are in good agreement with the data from electrotechnical measurements.
