SUMMARY OF A WORKSHOP ON HIGH HEAT LOAD X-RAY OPTICS HELD AT ARGONNE-NATIONAL-LABORATORY

A workshop on High Heat Load X-Ray Optics was held at Argonne National Laboratory on August 3-5, 1989. The workshop was co-sponsored by the Advanced Photon Source and the European Synchrotron Radiation Facility and served as a satellite conference to SR189. The object of this workshop was to discuss recent advances in the art of cooling X-ray optics subject to high heat loads from synchrotron beams. The cooling of the first optical element in the intense photon beams that will be produced in the next generation of synchrotron sources is recognized as one of the major challenges that must be faced before one will be able to use these very intense beams. Considerable advances have been made in this art during the last few years, but much work remains to be done before the heating problem can be said to be completely solved. Special emphasis was placed on recent cooling experiments and detailed "finite-element" and "finite-difference" calculations comparing experiment with theory and extending theory to optimize performance.
