The low energy beam transport line for the MYRRHA accelerator

Abstract : The MYRRHA Project aims at the construction of a new research reactor in Mol (Belgium) to demonstrate the transmutation feasibility with an accelerator-driven system (ADS). In its subcritical configuration, the MYRRHA facility requires a proton flux with a maximum power of 2.4 MW (600 MeV – 4 mA). Such a continuous wave (CW) beam will be delivered by a superconducting linear accelerator (linac) which must fulfil very stringent reliability requirements to ensure the safe ADS operation with a high level of availability. The proton beam will be injected in the superconducting linac with an energy of 17 MeV. The injector will enable to condition and pre-accelerate the proton beam from 30 keV to 17 MeV. The injector is composed of: the proton source, the low-energy beam transport line (LEBT), the Radio-frequency quadrupole (RFQ), and a series of CH-DTL cavities. Due to the very-high reliability requirements it is absolutely necessary to carry out prototyping of all the elements of the accelerator in order to optimise its operation. In this purpose a LEBT prototype has been built and is presently installed and operated at LPSC Grenoble (France). An experimental programme to optimise the tuning of the line, the beam transport and to study the space-charge compensation mechanism, is in progress. Once the line is commissioned it will be moved to Louvainla- Neuve (Belgium) to be coupled with the RFQ. We here review the construction and the commissioning of the LEBT. Some experimental results are discussed, in particular the observed space-charge compensation effects.
