Design of the spoke cavities and its associated cryomodule for the MYRRHA superconducting LINAC

Résumé

The MYRRHA Project aims at the construction of an accelerator-driven system (ADS) at MOL (Belgium) for irradiations and transmutations experiments purposes. The facility will feature a superconducting LINAC able to produce a proton flux of 2,4 MW (600 MeV – 4 mA). The first section of the superconducting linac will be composed of 352 MHz (beta = 0.37) spoke type superconducting cavities housed in short two cavities cryomodules operating at 2K. A first R&D phase on the Spoke cavities design and performances has been initiated in 2015. The first results on the performances of two prototypes designed for the MHYRRA LINAC, tested at 2K are presented. The cryomodule has for main design constrains the availability and the reliability required by the operation in a nuclear plant environment. To fulfil these requirements several solutions have been taken into account and especially the so-called “Fault-tolerance” scheme that will be used to operate the proton beam. The second part of the paper describes the whole cryomodule design (spoke cavities, Cryostat, Power Coupler, Cold Tuning System…) by mainly focusing on the conceptual choices driven by the reliability and fault tolerance scheme requirements.
