Abstract

The new Gamma Beam System (GBS) of the ELI-NPproject [1], currently under installation in Magurele (RO)by INFN, as part of EuroGammas consortium, can providegamma rays that open new possibilities for nuclear photonicsand nuclear physics.ELI-NP gamma rays are produced by Compton back-scattering to get monochromaticity (0,1% bandwidth), highflux (1013photons), tunable direction and energy up to19.5 MeV. Such gamma beam is obtained when a high-intensity laser collides a high-brightness electron beam withenergies up to740 MeV, a repetition rate of100 Hz, withtrains of 32 bunches within the same RF bucket.An advanced Machine Protection System (MPS) has beendeveloped, in order to ensure proper operation for this chal-lenging facility. The MPS operates on different layers of thecontrol system and is interfaced with all its sub-systems. Forinstance, it comprises different kind of beam loss monitors(based on Cherenkov optical fiber), hall probes, fast currenttransformer together with BPMs, and an embedded systembased on FPGA with distributed I/O over EtherCAT, to mon-itor vacuum and RF systems [2], which require fast responseto be interlocked within one RF pulse.
