Typical in-vacuum undulators, especially long ones, have several associated engineering challenges to be accurate and precise; magnetic centerline stability, inner girder hangers, and magnet period to name a few. The following describes these issues in more detail and ADC’s methods solved these critical issues for long in vacuum undulators. ADC has designed, built and delivered Insertion Devices and Magnetic Measurement Systems to such facilities as; MAXLab (EPU, Planar-2, and Measurement System), ALBA and Australian Synchrotron Project (Wiggler), BNL (Cryo In-Vacuum), SSRF (In-Vacuum – 2, and Measurement System), PAL (In-Vacuum and Measurement System), NSRRC (In-Vacuum), and SRC (Planar and EPU). The information presented here uses data from a recent IVU we delivered to PAL. This IVU will be installed at Pohang Accelerator Laboratory (PAL) for U-SAXS (Ultra Small Angle X-ray Scattering) beamline in 2011. The IVU generates undulator radiation up to ~14 keV using higher harmonic (up to 9th) undulator radiation with 2.5 GeV PLS electron beam
