A simple and compact high-voltage switch mode power supply for streak cameras

Abstract

The design and development of various high-voltage switch mode power supplies (SMPSs) for use with streak cameras are described. This work details −15 kV(100 µA), ±2 kV (1 mA) and ±1 kV (1 mA) SMPSs for biasing the streak and image intensifier tubes, driving the sweep circuit and positioning the photoelectron beam on the phosphor screen of the streak camera respectively. The design of the high-frequency pulse transformer-the main part of these SMPSs-is also presented.
