Oral

The CMS tracker Power Supply System is made out of 2000 power supply modules where LV and HV channels are grouped together. A dedicated quality assurance plan, using a complex, remoted controlled Test Fixture, has been developped in collaboration between INFN-Torino and CAEN spa to test each single channel during and after production. Details on the test procedure and results that have...

29. Evaluation and testing of advanced low-voltage power supplies

Bruno Allongue (CERN)

27/09/2006, 14:40

Oral

Following a process of proof-of-concept on the requirements for radiation and magnetic filed tolerant low-voltage power supplies to be used to power silicon detectors in LHC experiments, a common procurement action was undertaken by the experiments and PH-ESS group. The evaluation and testing of advanced COTS radiation and magnetic field tolerant low-voltage power supplies is...

73. : Distributed low voltage power supply system for front end electronics of the TRT detector in ATLAS experiment

Zbigniew Hajduk (Institute of Nuclear Physics PAN - Cracow, Poland and CERN Geneva)

27/09/2006, 15:05

Oral

We present a low voltage power supply system which has to deliver to the front end electronics of the ATLAS TRT detector ca. 24 kW of electrical power over the distance of 40-50 m (which adds another 24 kW). The system has to operate in magnetic field and under radiation environment of the LHC experimental cavern. The system has ~ 3000 individual channels which are all monitored and...

82. Electromagnetic Compatibility of a Low Voltage Power Supply for the ATLAS Tile Calorimeter Front-End Electronics

Georges Blanchot (CERN)

27/09/2006, 15:30

Oral

The front end electronics of the ATLAS Tile Calorimeter is powered by DC/DC conveters that sit close it. The performance of the detector electronics is constrained by the conducted noise emissions of its power supply. A compatibility limit is defined for the system. The noise susceptibility of the front end electronics is evaluated, and different solutions to reduce the front end...
