The Vacuum Interface Compatibility Experiment Vice Supporting the MYRRHA Windowless Target Design

The MYRRHA accelerator-driven system (ADS) is being developed in Mol, Belgium incorporating a windowless spallation target, as this is the only option within the constraints of the envisaged neutron source performance. In this paper the research programme and experimental set-up required for the R&D effort towards the conditioning of Pb-Bi eutectic for use in a windowless liquid-metal spallation target are presented. The experiences acquired commissioning the set-up, the current status of the experiment and first results are discussed.
