  1. Injector Laser Heater Undulator Jose Chan

  2. Injector Laser-Hearter Undulator • Problems/Issues: Paul E. “Most OTR screens are unusable due to COTR (laser heater should fix this in FY2009)” • PRD 1.2-004-r2: “…produces Laudau damping in the bunch compressor chicanes in order to suppress potential micro-bunching instabilities that may be driven by Coherent Synchrotron Radiation (CSR) in the bunch compressors, and Longitudinal Space Charge (LSC) forces in the linac…” • Engineer: Richard F. Boyce

  3. Laser-Heater System

  4. Status • Received and tested four bend magnets, BXH • Completed drawings for the vacuum chamber with OTR bodies and is in MFD • Available in September 2008 • Prints for the alignment stages are complete • Undulator magnets are out for vendor quote • Bids are due back on 6/25/08 • Undulator design are being finalized • Optical components are on order • Start installation in September 2008

  5. BX magnet OTR with photo-diodes 9 period adjustable gap undulator Beam

  6. Summary • Injector Heater design has started and stopped many time • More complicated than original thought • Very tight space requirement • Magnets and optical components purchase orders are in purchasing group • Final design packages are being completed • Undulator magnet installation maybe one month late depending on magnetic measurements • Expect to start installation of vacuum chamber in September 2008
