WP2 will be dedicated to the accelerator R&D for MYRRHA. The contents of the work package has been defined following the recommendations of the FP7 MAX project final report and addresses the topics that have been identified as priority ones to successfully pursue the research, design and development of the MYRRHA accelerator and prepare for its actual construction. These topics are listed here below.
- Beam characterization. “Correct (i.e. conform to reality) initial beam data are of fundamental importance in all beam dynamics simulation tools. Making use of the platform consisting of the ECR ion source and the LEBT that is presently under construction in SCK•CEN, an experimental campaign for fully characterizing the emerging beam (beam entering into the RFQ) should be launched.” This need will be especially answered in MYRTE WP2 through Tasks 2.4 and 2.8.
- Injector demonstration. “The injector has to be investigated in detail, in a step-by-step approach allowing for testing with beam. The logical first step is thus the construction of the 4-rod RFQ that has been designed in MAX and coupling it to the source-LEBT assembly presently under construction. This obviously implies the procurement of all the auxiliary equipment. The solid state RF power amplifier and the digital LLRF will themselves be prototype items.” This need will be especially answered in MYRTE WP2 through Tasks 2.1, 2.2, 2.3, and 2.7.
- Superconducting cavities demonstration. “Since the superconducting linac is highly modular, thorough prototyping is very efficient. The MYRRHA-type spoke cryomodule has been fully designed in MAX and should now be constructed and tested.” This need will be especially answered in MYRTE WP2 through Tasks 2.10 and 2.11.
- Reliability modelling. “The effort around the reliability modelling tool put in place by MAX should be pursued with vigour so as to obtain confidence and predictability. This tool is indispensable for the optimisation task.” This need will be especially answered in MYRTE WP2 through Tasks 2.9 and 2.12.
Smart and Reliable Control. “A virtual accelerator, performing on-line machine modelling with real-time machine data, will be a powerful and essential operational tool in the high reliability context. It is challenging, though, both from the simulation and from the control system point of view. The injector tests should serve such a development.” This need will be especially answered in MYRTE WP2 through Tasks 2.5 and 2.6.
