The European Organization for Nuclear Research, known as CERN is an international organization whose purpose is to operate the world’s largest particle physics laboratory, which is situated in the northwest suburbs of Geneva on the Franco–Swiss border.

EEI designed and manufactured two different series of fundamental equipment for the LHC particle accelerator:

• The 26V – 20kA Power Converter is now used to supply the superconductive magnetic dipoles of the CMS.

2018 : The second power converter 26V – 20kA used for test facility and as the spare unit of the Compact Muon Solenoid power supply in the LHC.

• The 444 four-quadrant AC/DC converter with +/- 600A/10V output used for the power supply of the superconductive dipoles placed in the tunnel.

CERN: QUADRUPOLE MAGNET POWER SUPPLIES FOR THE HIE ISOLDE PROJECT

• A set of 19”, air-cooled, 1-quadrant, 200A -50 V voltage-controlled switched-mode power supplies were provided to CERN. They feature very low noise emissions (comparable to linear power supplies), 1 kHz control bandwidth, earth fault detection circuit and a customized analog/digital interface. The power supplies have a modular design in order to reduce the repair time.

EEI received from CERN the “CMS Gold Award of the Year 2004” for the best Italian Electrical Supplier of the 2004.
