Description

The High energy Engineering X-ray (HEX) Diffraction beamline at the National Synchrotron Light Source II (NSLS-II) at Brookhaven National Lab (BNL) is the first high-energy beamline which reaches up to 150keV for monochromatic beam. The 1.2m long HEX-SCW has been developed with Bilfinger Noell with a period length of 70 mm and field strength on-axis of 4.3 T with vacuum aperture of 8mm. Magnetic measurement of the SCW is conducted using a novel in-vacuum Hall mapper and an in-vacuum flip coil system at BNL. The in-vacuum Magnetic Measurement System (IVMMS) which was originally developed for 1.5m-long CPMUs has been repurposed to obtain 1.9 m measurement stroke. Three Lakeshore probes and a Cernox® sensor are placed in a sled made of Vespel®. The in-vacuum flip coil system is constructed with COTS components by UHV Design. System descriptions and measurement results are presented.
