Abstract
A slow cycling flux pump has been constructed where operation is controlled by digital logic driving a high power operational amplifier. Hall sensors allow closed loop control of the secondary currents to enable switching the heater driven power cryotrons at the optimun time. Operating efficiency of 87% has been achieved.
