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