| Abstract |
The Extremely Brilliant Source (EBS) of the ESRF will hold new type of X-Ray absorbers: a new material will be used (CuCr1Zr suggested by *) together with a novel design integrating: - CF flange are machined in the absorber body. No weld, no braze. - Optimized toothed surface profile, reducing the induced thermal stresses. - Compton and Rayleigh scattering integrated blocking shapes. - Concentric cooling channels. A brief overview of the new design and concepts will be given. The presentation will then focus on thermo-mechanical absorber ANSYS calculations, combining both Computational Fluid Mechanics (CFD). The calculations and the calculation process will be discussed as well as the design criteria chosen by the team. The CFD calculations will show that an heat transfer coefficient between the water and the copper part can be estimated as well as the pressure drop through the absorber. Finally, the stress analysis will be emphasized. The type of stresses (tensile, compressive or shear) and their nature (primary or secondary) will be linked to the choice of design criteria.
