LHC power supplies and crates

The ESE group runs a service to help evaluate, purchase, test and maintain power supplies for use in experiments at CERN. Large quantities of power supplies have been purchased for the use in the LHC experiments. The repair of these are organized by this service via specific maintenance contracts with the manufacturers.

Information on the power supply units are stored in a database. It includes technical information as well as procedures for ordering and repairing devices.


ESE has evaluated power supplies for xTCA crates and other modular systems. Details can be found here.

ESE manages a procurement contract for ATCA equipment. Details can be found here.

ESE also evaluated ATCA equipment. Test reports are available here.
