Title: Programmable photomultiplier power supply

This paper describes a precision photomultiplier power supply that provides compensation of errors introduced by switch losses, and compression of the range of scale resistors required with introduction of digital control data into the low-voltage branch of the inverse feedback divider. Parameters are as follows: U /SUB out/ =0.5-2kV, I /SUB out/ =0.5 mA, step size /SUB d/ U /SUB out/ =1 V; uncertainty deltaoU /SUB out/ less than or equal to /SUP +or-/ 0.5V; temperature drift delta U /SUB out/ less than or equal to /SUB +or-/ 5 10 T%/K; time drift deltaU /SUB out/ (T)less than or equal to /SUB +or-/ 10 S%/10h; output ripple U aboutless than or equal to30 mV.
