Preliminary Study for Pulsed Powering in Particle Detector Systems

In particle physics detectors, the standard solution in supplying power to detector modules is to apply direct current over cables. We investigate the possibility and advantages of using a pulsed powering scheme. Pulsed powering shows promise in achieving 2-wire point-of-load voltage regulation over typical ATLAS low voltage power cables. For some detectors, this could be a reliable and serviceable solution for point of load voltage regulation in the high radiation environments at the high luminosity LHC. Pulsed powering might also be exploited on existing ATLAS Pixel low voltage power cables to provide an inexpensive solution for the elimination of voltage offsets among Pixel detector subsystems.
