Control system prototype complete. Mechanical systems will be factory-tested by mid Feb. 2012. In-Vacuum Undulators (U21 for SRX with options for two more & two U20)  Both contracts were signed on Dec. 20 th, 2011. CDR is scheduled on Jan.30 th, 2012. In-Vacuum Undulator (U22L for IXS)  The dead line for the proposals was January 25 th, 2012. Elliptically Polarized Undulator (CSX-EPU)  PDR completed in Oct. 2011. FDR is scheduled in Feb. 2012. Three Pole Wiggler (3PW)  FDR completed in June 2011. Design change of magnets resulted in delay. Magnet Development Laboratory (Insertion Device Magnet Measurement Facility)  The facility is ready for operation

7. 7 BROOKHAVEN SCIENCE ASSOCIATES Damping Wiggler Status (Danfysik) Prototype of Mechanical Drive System has been tested successfully. Construction continues on Structural Frames and Magnet Girders [60%]. Machining of Magnet Assembly parts and other special tooling has begun [15%]. Permanent Magnets order (Vacuumschmelze) part 1/3 is due next month. Control scheme & rack layouts are developed; assembly continues. Subcontractor needs to set up the proper BNL rack layouts (heat loads, internal fans, flow direction, ampacity). [80%] PDR completed on Jan. 10 th for the contract for the Vacuum Chamber (FMB-Berlin) and supports. [25%]

11. 11 BROOKHAVEN SCIENCE ASSOCIATES EPU Status FDR scheduled in February 2012 Since PDR (October 2011) slight mechanical changes to align the gap drive system along the vertical forces, which has resulted in two months delay. A separate RFP for its vacuum chamber has been issued. Permanent magnets by Neomax have been shipped. Courtesy of Kyma Undulator Top Level Schedule

15. 15 BROOKHAVEN SCIENCE ASSOCIATES 3PW-Major Change (Nov/2011) New dimensions of magnets and poles: Main pole: 110mm x 23mm x 67mm (120mm x 23mm x 65mm/old dimensions) End pole: 90mm x 45mm x 82mm (101mm x 45mm x 86mm/old dimensions) Main magnet: 150mm x 28.9mm x 100mm (120mm x 41mm x 90mm/old dimensions) New 3PW model The contract was originaly issued with 3,5 and 10 device options. The manufacturer underestimated the price of magnets ($20,000 for ten magnets in their estimate v.s. $150,000 in reality). Instead of paying $130,000 extra, we have decided to use excess magnets from DW contract and redesign the structure. Slight cost addition for the design change (< $10k).

16. 16 BROOKHAVEN SCIENCE ASSOCIATES IVU Status U21-1.5m for SRX (Hitachi Metal, USA) : The original contract was signed by BNL on 11/21/2011 The final contract was signed by Hitachi Metal, USA on 12/20/2011 Options for two more identical (slight period change inclusive) devices, one set of prices within 60 days from the start of the base contract, another set within 180 days. CDR was scheduled on January 31 st, 2012. U20-3m (Hitach Metal, USA) : The original contract was signed by BNL on 11/21/2011 The final contract was signed by Hitachi Metal, USA on 12/20/2011 CDR was scheduled on January 31 st, 2012. U22L-3m for IXS (No source determined yet) The proposal deadline was January 25 th, 2012. No options are included.

18. 18 BROOKHAVEN SCIENCE ASSOCIATES In-Vacuum Magnetic Measurement System (IVMMS) IVMMS contract with Toyama, Inc., Japan) Linear motor based design has been adopted. Various vacuum lubricants have been tested without much success. Next one to try is CVD coating of MoS 2 on balls for ball bearings. FDR is scheduled on Feb. 7 th, 2012 Test to measure the field of the SRX-IVU in vacuum will take place at the Neomax Engineering factory around October 2012.
