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

  4. DW, EPU and 3PW Schedules

  5. IVU (U20, U21 for SRX, U22L for IXS ) Schedules

  6. Progress since Last ASAC (May2011) • Status of Each Baseline Device PM Damping Wiggler (Six DWs)  FDR completed on June 7th, 2011. 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. 20th, 2011. CDR is scheduled on Jan.30th , 2012. In-Vacuum Undulator(U22L for IXS)  The dead line for the proposals was January 25th, 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. 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. 10th for the contract for the Vacuum Chamber (FMB-Berlin) and supports. [25%]

  8. DWs: Structural Frames & Magnet Girders Machining and Fabrication by Nortemecánica

  9. DW Chamber Preliminary Design by FMB

  10. Damping Wigglers (6 x DW) Top Level Schedule

  11. 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.

  12. EPU Vacuum Chamber Details

  13. SRP Requirement for ID Vacuum Chambers Mis-steered E-beam “Steady State” Cases within Interlock limit “Transient Cases” with possible maximum beam angle

  14. Ex. for a “Transient Case” Linear Horizontal Mode 1msec 10msec

  15. 3PW-Major Change (Nov/2011) • 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). 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

  16. 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 31st , 2012. • U20-3m (HitachMetal, 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 31st , 2012. • U22L-3m for IXS (No source determined yet) • The proposal deadline was January 25th, 2012. • No options are included.

  17. ID-Magnetic Measurement Facility (MMF) Hall probe bench ready Flip Coil system ready RT-Calibration Dipole ready (Cold version being prepared) Helmholz Coil System ready Hall Probe bench and Flip Coil system Helmholz Coil System Calibration Dipole System

  18. 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 MoS2on balls for ball bearings. • FDR is scheduled on Feb. 7th, 2012 • Test to measure the field of the SRX-IVU in vacuum will take place at the Neomax Engineering factory around October 2012.

  19. Vacuum Seal Test • 4m long rectangular opening • Two baking tests have been conducted with leak rate less than 1E-9 torr/l (Success) • Leak starts after the third thermal cycle.

  20. Low temperature M-H measurement of High CoercivityPrFeB magnets at the Louis Néel laboratory • An efficient 8 T extraction vector magnetometer with sample rotation for routine operation, • D. Dufeu, E. Eyraud, and P. Lethuillier REV. SCI INS. VOL 71, NB 2

  21. PrFeB Arrays Baking Test • Baking test of PrFeB arrays (lu=17mm) with 47CR • Repeatability test with a few detachment / attachment of arrays to the frame • Negligible variations • Baking test (up to 100C)  Less than 0.2% p-p field decrease • Cold field measurement using VTF is planned next, then increase the baking temperature for further test.

  22. Summary • Damping Wigglers • On (revised) schedule. Revision was necessary due to the delay in magnet procurement by the vendor. • EPU • Two months behind the schedule due to mechanical design changes. • A separate RFP for the vacuum chamber has been issued.. • 3PW • A revised design using excess DW magnets has been adopted. • IVU • U21 for SRX : Contract signed on 12/20/11, 60/180 day options for two additional devices. • Two U20-3m: Contract signed on 12/20/11, No option included. • U22L-3m for IXS: Proposals were due on 01/25/12. • ID-MMF • Ready for operation
