Magnetic Material Specification and Procurement Strategy

1. Magnetic Material Specification and Procurement Strategy Dawn Munson

2. Magnetic Material Specification • Material properties requirements are detailed in LBNL Engineering Specification – 10620 • Magnetic Properties • Mechanical Properties • Magnetic Testing • Packaging and Shipment • Acceptance Criteria • This specification in conjunction with mechanical detail drawings and the contract will dictate the magnets for the LCLS-II undulators. LCLS-II Magnetic Structure Review 7-6-11

3. Magnetic Material Specification • The volume of magnetic material needed for both undulator type blocks will likely require more than one manufacturing lot • To maintain continuity, it will be required that any one shipment contain material from a single manufacturing lot • At a minimum, a shipment is the quantity of blocks required for a single HXU or SXU undulator LCLS-II Magnetic Structure Review 7-6-11

4. Magnetic Material Specification • Magnet block coating • Requirement is for Aluminum 0.010 mm to 0.020 mm thick • Based upon ALS experience • Proprietary coatings are likely to be proposed by potential vendors. Acceptance of this coating will be dependent on radiation exposure testing* and is compatible with LoctiteHysol® EA9360™ epoxy adhesive • Prototype blocks may use a coating other than aluminum with the provision that testing is to be completed before production begins on the full order *Requirement applies to coatings with organic content, such as VACCOAT 10047 LCLS-II Magnetic Structure Review 7-6-11

5. Procurement Strategy • Goal: to qualify two vendors for future procurement of blocks for full scale prototypes and production • Request for Proposal will solicit quotations for: • Prototype HXU blocks – four standard magnet modules and eight end modules • Prototype SXU blocks - four standard magnet modules and eight end modules • Will include tooling as separate items • Will include options for production quantities • Initial procurement will be for HXU prototype blocks • LBNL Buyer – Gina Goodman LCLS-II Magnetic Structure Review 7-6-11

6. Procurement Strategy - Costs • Based upon estimated cost of $8.2M/m3* • HXU: ~$150/block • 34 periods per module, 2 blocks/period: $10.2K/module • 106 periods per device, 4 blocks/period: $63.6K/device • 32 devices: $2.04M total • SXU: ~$650/block • 19 periods per module, 2 blocks/period: $24.7K/module • 61 periods per device, 4 blocks/period: $158.6K/device • 18 devices: $2.86M total * Estimates are based on ALS historical material costs LCLS-II Magnetic Structure Review 7-6-11

7. Procurement Strategy - Acceptance • Acceptance Criteria • Documents detailing the representative magnetization of each material lot • The data file from the block measurements, in ASCII format • Documentation detailing any surface void or chips larger than 1 mm3 • Testing verification and documentation of any alternate coating for the magnet blocks • All tooling and materials as outlined in the purchase contract LCLS-II Magnetic Structure Review 7-6-11

8. Procurement Strategy - Tracking • Material test reports • Block measurement files • Production photographs • LBNL and/or the selected assembly sub-contractor will visually inspect all magnet blocks • Random blocks will be selected and tested to verify the data supplied by the manufacturer LCLS-II Magnetic Structure Review 7-6-11

9. Procurement Strategy - Schedule • Schedule: • Release RFP end of July • Award end of August • Take delivery of prototype magnets ~February, 2012 • Full scale prototype block purchase ~July, 2012 • Production procurement award ~July, 2013 LCLS-II Magnetic Structure Review 7-6-11
