Abstract :
The Tevatron QXR (Quadrupole Extraction Regulator) power supply is a linear current pulser combined with a dc transistor regulator. The pulser produces programmable current pulses of up to 250 amps with a maximum duration of 12 ms and a maximum voltage drive of +200/-250 volts. Its fastest repetition rate is 1 Hz. Between pulses a single power transistor regulator maintains 0 to 50 amps in the quadrupole magnet load. The pulser is an air-cooled 34 FET transistor bank operating in the linear region.
