Phys. Rev. ST Accel. Beams 2, 112801 (1999) [10 pages]Method for reducing x-ray background signals from insertion device x-ray beam position monitors
A method is described that provides a solution to the long-standing problem of stray radiation-induced signals on photoemission-based x-ray beam position monitors (BPMs) located on insertion device x-ray beam lines. The method involves the introduction of a chicane into the accelerator lattice that directs unwanted x radiation away from the photosensitive x-ray BPM blades. This technique has been implemented at the Advanced Photon Source, and experimental confirmation of the technique is provided.
