High power primary beam dump prototype testing accomplished

10 May 2013

The high power beam dump is required to intercept all primary beam at powers of up to 325 kW. The water-filled drum rotates at 400 rpm while water flows through it at 60 gpm.

In collaboration with Oak Ridge National Laboratory (ORNL), the prototype drum was tested at ORNL to verify the water flow and heat transfer simulations were accurate and that no cavitation or bubble retention was observed.

The results support the baseline design and have led to further design enhancements that will also be tested at ORNL.
