Construction and measurement techniques for the APS LEUTL project RF beam position monitors

Abstract

The design, construction, and assembly procedure of 24 RF beam position monitors used in the Advanced Photon Source low-energy undulator test line and linear accelerator (linac) are described. Beam stability as well as beam positioning capabilities are essential to the LEUTL project. A design objective of the LEUTL facility is to achieve better than 1-/spl mu/m resolution. The highest care was used in the mechanical fabrication and assembly of the BPM units. The latest experimental results using these BPMs are presented.
