Abstract
The IFMIF-EVEDA accelerator will be a 9 MeV, 125mA cwdeuteron accelerator prototype for verifying the validity of the accelerator design for IFMIF. A beam stop will be used for the RFQ and DTL commissioning aswell as for the EVEDA accelerator tests. Therefore, this component must be designed to stop 5MeV and 9MeV deuteron beams with a maximum power of 1.13MW. The first step of the design is the beam-facing material selection. The criteria used for this selection are low neutron production, low activation and good thermomechanical behavior. In this paper, the mechanical analysis and radioprotection calculations that have led to the choice of the main beam dump parameters will be described. The present design is based on a conical beamstop (2.5mlength, 30cmdiameter, and 3.5mmthickness) made of copper plus a cylindrical 0.5m long beam scraper. The cooling system is based on an axial high velocity flow of water. This design is compliant with the mechanical design rules during full power stationary operation of the accelerator. The radioprotection calculations performed demonstrate that, with an adequate local shielding, doses during beam on/off phases are below the limits.
