The AMS brick: an HV power supply for the space experiment AMS-02

AMS is a particle physics experiment in space. The purpose is to perform accurate, high statistics, long duration measurements of the spectra of energetic (up to multi-TeV) primary charged cosmic rays in space. This article describes the high voltage power supply for the AMS-02. This system was the brick, a set of interconnected modules (boxes) which contains DC/DC converters to generate high voltage from the 28 V DC available from the space station (BOX HV-DC/DC), linear regulators to fine adjust the voltage of each photomultiplier (BOX HV-LinReg) and logic board with the digital link that sets and monitors the various voltages (xPSC).
