Abstract
A synthetic-diamond-based X-ray transmitting beam-position monitor has been studied using focused white beam at the National Synchrotron Light Source X-25 wiggler beamline. Of particular interest are the possibilities to design an integral window and filter/photon beam-position monitor for the Advanced Photon Source high-heat-flux insertion-device beamlines. The preliminary measurements were taken using two synthetic-diamond blade samples with different thicknesses and cooling configurations. The monitor (consisting of a vacuum vessel, an ion pump, a water-cooling base, a blade mounting block, and electric feedthroughs) was mounted on a three-dimensional ( x, y, φ) stepping-motor-driven stage with a 0.064-μm stepping size and a 0.1-μm linear encoder resolution. An infrared camera system was used to monitor and record the diamond blade surface temperature field through a sapphire window and test results are presented.
