DC–DC conversion powering for the CMS tracker at SLHC [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2011 Abstract A tracker powering scheme based on DC–DC converters close to the detector modules can supply more power through thinner cables. This will allow to satisfy the increased power demands of tracking systems at the SLHC. This article describes the development of DC–DC converters for upgrades of the CMS pixel and tracking systems and addresses ...
