The synchrotron radiation emitted by bending magnets, except for a small portion designated to beamlines, will be dissipated by crotch absorbers to protect downstream vacuum elements. SLS2.0 crotch absorbers are designed to have two water-cooled, toothed jaws made of Glidcop to dissipate a maximum heat power of 6 kW. Finite element analysis has been conducted to validate the thermal and mechanical strength of the absorbers’ mechanical design. A conjugate heat transfer (CHT) simulation, utilizing direct coupled solid and fluid zones with Computational Fluid Dynamics (CFD) software ANSYS Fluent, was performed to verify the water cooling concept. Furthermore, a prototype absorber underwent testing in an e-beam welding chamber, where the temperatures of the absorber and cooling water were measured and compared against calculated values. The test results not only confirmed the absorber’s ability to dissipate the specified heat load but also validated the thermal modelling methods. This presentation will focus on aspects of numerical simulation and thermal testing.
