| Research Abstract |
We proposed to investigate the use of coded-aperture imaging techniques for x-raybeam profile monitoring of beams with transverse beam sized below 10 μm. At the ATF2 extraction line, we built an x-ray beam line using the final upstream bending magnet as an x-ray source, and successfully measured beam sizes down to ~7.5 μm, the smallest beam size achievable through tuning of the extraction line optics. This beam size represents a new world record for the smallest beam size measured using x-ray coded aperture optics.We also developed parallel-processed code for analysis of beam profiles from coded aperture images, including non-Gaussian components.
