Abstract
The design and performance of a feedback amplifier for the precision control of the current through a 40‐kw magnet is described. The system uses the difference between the IR drop in a standard resistor and a preset potentiometer voltage to control the current. The principal components are a high gain vibrator amplifier and a stabilized power amplifier incorporating a commercial motor‐generator set. Current fluctuations are kept below one part in a million.Keywords
