  3. NSLS-II Insertion Devices (Baseline Project Scope)

  4. DW, EPU and 3PW Schedules

  5. IVU (Standard & SRX) Schedules

  6. Progress since ASAC10 (October) • Status of Each Baseline Device • PM Damping Wiggler (DW) •  Contract was issued on Nov.7, 2010. PDR completed. FDR is scheduled in a few weeks. • In-Vacuum Undulator (SRX-IVU & Standard IVU) •  RFPs are being prepared. • In-Vacuum Undulator (IXS-IVU) •  Reference mechanical design has been completed. Spec and SOW are finalized. • Elliptically Polarized Undulator (EPU) •  Contract was issued on April 28, 2011 • Three Pole Wiggler (3PW) •  Contract was issued on March 25, 2011. PDR was conducted on May 6th. • Magnet Development Laboratory (Insertion Device Magnet Measurement Facility) • Hall probe bench has been commissioned with various probes. • Calibration Dipole is in place. • Helmholz coils are in place (1 Hz environmental noise issues remain). • Integrated Field Measurement System (IFMS) will be delivered by the end of May.

  7. DW Status • PDR has been completed with action items clearly identified. FDR scheduled in late May. • Weight limit spec must be altered (max 10T  11T) in order to maintain the rigidity of the structure given the envelope. • RFP for the vacuum chambers has been issued. Courtesy of Danfysik

  8. EPU Status • Contract was issued on April 28th, 2011. • A separate RFP for its vacuum chamber is prepared. • PCR is expected to replace the central canting magnet with PM canting /phasing magnet system. • Investigation to eliminate end canting magnets by using slow correctors is in progress.

  9. 3PW Status • The contract was issued on March 25th, 2011 with 3,5 and 10 device options. • PDR meetings took place on May 6th. • Final adjustment for vacuum chamber design change is carried out. Courtesy of ADC

  10. IVU Status • SRX-IVU • Specification and SOW are being circulated for signatures. • Tight specs: 1 mm/s to 0.1mm/s scan while maintaining 2 degree phase error. • Standard IVU • Specification and SOW are being circulated for signatures. • IXS-IVU • 3m long BNL reference mechanical design has been developed in the given device envelope (Long straight section requires narrower frame than that for short straight section).

  11. ID-Megnetic Measurement Facility (MMF) • Clean Room has been completed • Hall probe bench in operation • Calibration Dipole in operation • Flip/long coil system (IFMS) to be delivered by the end of May • Helmholz Coil System • Vendor specs cannot be fulfilled due to environmental noises • Investigation work in progress. Hall Probe Bench Calibration Dipole System Flip/Long Coil System

  12. Remaining R & D (1.02.01.03) • In-Vacuum Magnetic Measurement System (IVMMS) • Conceptual design has been proposed • Linear motor solution is pursued instead of ball screw based design. • PDR is planned in mid May.

  13. Remaining R & D (1.02.01.03) cont’d • Vacuum Seal Test (VST) • Fabrication started. • Tests will be completed by August. • Illustration of VST assembly being rolled into furnace

  14. New R & D • Bakable PrFeB arrays • Magnets are ready • Vendor is fabricating the array structure and fixture • Baking test is planned in June. • Cold measurement is planned to be in August provided that the cryogenic safety approval for modified VFT is obtained in time.

  15. Summary • Damping Wigglers (Danfysik) • FDR is scheduled in late May. • EPU • Contract was signed with Kyma undulator, srl. on April 28th, 2011. • Vacuum chamber procurement is in progress • IVUs • RFPs for SRX-IVU and standard IVU are prepared. • Reference mechanical design has been developed for IXS-IVU. • 3PW • Contract was signed with ADC, inc. Kick-off meetings started. • Vacuum chamber has been modified to leave more space from a slow corrector. • ID-MMF • Most of the equipment are in place. • R&D • IVMMS (1.5m) is in design stage. • VST result will be available by August. • PrFeB magnet arrays are in fabrication. Baking test and cold measurement are planned.
