TI - Five Years of Operations for the Magnet Power Supplies of FERMI J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - FERMI, the FEL light source in Trieste, Italy, started its regular operation with external users in 2012. The construction of the facility began in 2008 and the commissioning of the complete system – LINAC, Undulators’ chains (FEL-1 and FEL-2), photon front-end – started in 2010. On December 13, 2010 the first lasing occurred. From the Photo-injector to the electron Main Beam Dump (MBD), there are more than 400 magnets and coils, including those mounted on the accelerating sections of the LINAC and on the Undulators. With few exceptions, each magnet power supply energizes a single magnet/coil: there are about 400 magnet power supplies spanning from few tens of watt up to 42 kW. The power supplies types range from custom-made ones, to COTS (Commercial Off The Shelf), to in-house design (these accounting to 88% of the total). Almost all magnet power supplies are in use since mid-2010. During 5 years of operations, the reliability of the magnet power supplies proved to be extremely high: the downtime of FERMI operations due to magnet power supplies is very low.
