Abstract
Measurements were made on Burle C83062 and Hamamatsu R2497 type photomultiplier tubes (PMTs) to determine an optimum method for remotely controlling their gain. The tubes´ gain was varied by three different methods and energy and time measurements were done to determine the tube performance of each method. One method was chosen as optimum for its 10:1 gain range with only 250-ps time shift. A circuit was implemented as a computer-controllable PMT gain setting circuit which emulated this method. The circuit has applications in positron emission tomography, high energy physics, and virtually any radiation detection system involving PMTs
