Developments and Tests of a 700 MHz Cryomodule for the Superconducting Linac of MYRRHA

The MYRRHA projects aims at the construction of an Accelerator Driven System demonstrator. The criticality will be sustained by an external spallation neutron flux; produced thanks to a 600 MeV high intensity proton beam. This beam will be delivered by a superconducting linac which must fulfil very stringent reliability requirements. To carry out “real scale” reliability-oriented experiments a 700 MHz Cryomodule was developed. Several tests were performed to commission the experimental set-up. We review here the obtained results and the lessons learnt by operating this module, as well as the on-going developments.
