Buncher-Cavities for the MYRRHA Injector LINAC — •Daniel Koser, Markus Basten, Dominik Mäder, Daniel Noll, Holger Podlech, Ulrich Ratzinger, Malte Schwarz, Anja Seibel, and Markus Vossberg — Institute for Applied Physics IAP, Frankfurt am Main, Germany

MYRRHA (Multi-purpose hYbrid Research Reactor for High-tech Applications) is currently being designed as an Accelerator Driven System (ADS) for demonstrating the feasibility of transmutation of high level nuclear waste. The MAX project (MYRRHA Accelerator eXperiment and development) is the corresponding R&D programme for the designated proton driver, which should provide the spallation target with a continuous wave proton beam of 600 MeV and 4 mA.

The current layout of the injector design includes a 2-gap as well as a 5-gap room temperature rebunching structure operating at 176,1 MHz with total effective voltages of 116 kV and 270 kV, respectively, which both are being designed at IAP. For maximum power efficiency the 2-gap structure is going to be implemented as a quarter-wave coaxial resonator whereas the 5-gap structure will be a CH cavity, for which a prototype was already built within the scope of FRANZ.

In order to optimize the performance and to provide a reliable cooling system and mechanical stability, RF, thermal and structural mechanics simulations are done mainly using CST Studio. Also the beam dynamics is going to be investigated using a new particle in cell tracking code called BENDER, which was developed at IAP.
