Abstract [en]

The insertion devices in the MAX IV 3GeV accelerator ring produce some of the most intense beams of synchrotron radiation. This is a benefit on the sample, allowing to measure weakly scattering phenomena in short time, but a problem for components preprocessing the beam. Without a careful consideration of heat load already in the design of these components, damage would be inevitable within a few seconds of exposure. Future insertion devices are foreseen to produce even more intense beams, and thus this design already needs to be updated. The goal of the project was to produce a numerical model for one such component, the so called heat absorber, and to use that model to evaluate the existing design and to find a new design which can withstand the increased heat load. The study was performed with the purpose of being used as support in upcoming procurements of equipment. It was conducted with the use of the finite element analysis code Comsol Multiphysics in a model coupling heat transfer, turbulent flow and solid mechanics modules. The heat loads by synchrotron radiation were simulated with help of the codes Spectra and Shadow3. Design criteria were low-cycle fatigue, as well as ease of integration and manufacturing. The study considers two materials commonly used in cases of high heat load, namely OFHC copper and Glidcop. It includes a parametric study of the existing design, an investigation regarding reflection and scattering of synchrotron radiation and a presentation of new design concepts. A revision of MAX IV's stress limits for in-vacuum OFHC copper components is also proposed.
