- Description
- The LCLS-II undulator phase shifter is a variable gap, pure permanent magnet (PPM) device. The phase shifter is used to correct and maintain phase between the LCLS-II electron beam and electromagnetic (radiation) field. SLAC has developed two magnet assemblies, each arranged in a 7-magnet Halbach configuration, for use in the HXR and SXR beam lines. The magnetic material shall be NdFeB, with magnets installed in a common holder with lateral and longitudinal adjustment capability for each magnet. Shims are to provide vertical magnet adjustment. The drive system utilizes a Servomotor to vary the magnetic gap, which is in turn monitored by an absolute encoder. The device must fit within a strict space envelope and have features to provide 6 degree-of-freedom (DOF) adjustment. Phase shifters must be delivered fully assembled, tuned, and fiducialized. Requirement will be for 1 prototype, and upon approval, Options of a production run of 20 SXR's and/or 31 HXR's each. • Minimum gap = 10 mm • Maximum gap = 100 mm • Gap height accuracy = +/- 28 µm • Minimum gap repeatability = 16 µm • Maximum gap change velocity = 10 mm/s • Gap encoder accuracy = 4 µm • Gap encoder resolution = 2 µm • Overall device adjustment resolution = 25 µm (all three principal DOF) • Approximate magnetic force at minimum gap = 190 lbf • Approximate magnetic force at maximum gap = 0 lbf • Magnetic axis fiducialization accuracy, lateral = 330 µm • Magnetic axis fiducialization accuracy, vertical = 70 µm Do not propose any pricing to this posting, this is a source sought by posting only.
