Spoke Cryomodule Prototyping for the MINERVA Project

Abstract : In the framework of the MINERVA (MYRRHA 100 MeV) project a first prototyping period started at the end of 2017. During this period a prototype cryomodule fully equipped (Spoke Cavities, Cryomodule Vessel, Cold Tuning System, Magnetic shielding, Power Couplers…) as well as its operating and controlling components (LLRF, RF amplifiers…) will be studied and manufactured. The aim of this prototyping period is first to complete the study of all the components and to validate the manufacturing and the assembling procedure in order to freeze the specifications for the serial construction. On the other hand the prototypes will serve as a test stand allowing to study and adjust the 'Fault Tolerance' strategy parameters, which is a challenging operating concept specific to the MYRRHA LINAC. This paper presents the various tasks related to this Spoke Cryomodule prototyping and their status.
