Description
A standardized magnetic measurement system exists for evaluating the field characteristics of conventional insertion devices, including in-vacuum undulators designed for NSLS-II, which employ a rectangular measurement window. A In-Vacuum Magnetic Measurement System (IVMMS) valid for 1.5 m long CPMU was developed during the NSLS-II project. However, in the case of cryogenic permanent magnet undulators (CPMUs), each facility implements its own design, and no commercially available measurement apparatus currently exists. At NSLS-II, we intend to retain a side rectangular window for room-temperature characterization. Consequently, a completely new in-vacuum Hall probe system good for longer devices than 1.5 m has been developed to interface with this window. This paper presents a preliminary design of the in-vacuum Hall probe measurement bench, designed to characterize a 3 m-long CPMU planned for the NEXT-III (NSLS-II Experimental Tools III) project beamline.
