Progress since Last ASAC (May2011)

• Status of Each Baseline DevicePM 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


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%]

DW Chamber Preliminary Design by FMB


Damping Wigglers (6 x DW) Top Level Schedule


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.

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).


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 (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 31st , 2012.

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


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

Calibration Dipole System

Hall Probe bench and Flip Coil system

Helmholz Coil System


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

MoS2 on 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.


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.


Low temperature M-H measurement of High Coercivity PrFeB 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


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.


Summary

• 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.

• EPU• Two months behind the schedule due to mechanical design changes.• A separate RFP for the vacuum chamber has been issued..

• Damping Wigglers• On (revised) schedule. Revision was necessary due to the delay in magnet

procurement by the vendor.

• 3PW• A revised design using excess DW magnets has been adopted.

• ID-MMF• Ready for operation
