摘要

The IFMIF-EVEDA beam dump is designed to stop a 9 MeV, 125 mA continuous wave deuteron beam that deposits along its surface a total of 1.125 MW. The beam dump design is based on a 2.5 m long copper cone whose inner surface absorbs the beam. This piece is cooled by water flowing at high velocity through the annular channel formed between it and a second piece (shroud) made of four truncated cones of slightly different slopes.

In this paper the beam dump cooling system will be briefly described, and the relevant 1D and 3D results will be presented paying especial attention to the computational fluid dynamics results.
