  1. Source Requirements, Work From Now to Make/Buy Milestone Toshi Tanabe Energy and Photon Sciences Directorate, Brookhaven National Laboratory, Upton NY 11973 HEX-PDR, April 26th, 2018

  2. Outline • Final specifications –RSI ver. 10. • Straight Section Layout • Procurement Plan (Plan A) • Plan B • Magnetic Measurement Plan • Summary

  3. HEX-SCW Current Specs for Users (RSI ver.10) Note 1: The fan angles of the radiation quoted here are as seen at 16m from the source, and take into account the effects of source length; the worst case fan size is taken. The two values quoted are for the points where the power density falls to values that are 1% and 0.1% of the central value. Designs of the fixed mask entrance shall take into account these fringe power loads.

  10. Possible Plan • Plan A: Procuring a turn-key SCW from a contractor with BNL specified controls and other electronics. • Pros: Fixed price contract. It is clear where the responsibility lies. • Cons: No technical expertise in case of failure. Political risk. Technical risk. • Plan B:Use (possibly modified ) APS designed cryostat with BNL built arrays (possibly with Nb3Sn wire) and electronics. • Pros: US built solution with in-house expertise in case of repair. Technology transfer has been (almost?) agreed by APS and NSLS-II. • Cons: Limited prior experience at BNL. Need upfront R&D. Integration with multiple labs. Potential performance risks.

  11. Decision Flowchart PDR PlanB Design Study RFP Yes No Plan B Bid? Plan A Yes No Prototype Acceptable? Full size Purchase In-House Measurement Yes No Rework Acceptable? Install

  12. Procurement Plan (Plan A) Straight RFP

  13. Possible Contractor List and Contact Person On March 27th, 2018 abbreviated SPEC&SOW were sent to the following possible contractors for budgetary estimate and comments. • Elettra (Italy) -- Estimate in progress • Contact: Dr. Emanuel Karantzoulis • Research Instrument (Germany) • Contact: Dr. Christian Piel • APS (US) -- Vertical race track design is preferred. No estimate. • Contact: Dr. YuryIvanyushenkov • Hitachi (Japan)– Asked about possibility of direct cooling design. No estimate. • Contact: Dr. Tomoyuki Semba • TPS (Taiwan)– Not Interested. • Contact:Dr. Ching-Shiang Hwang

  14. Plan B In-House Development

  15. APS Designed Cryostat for SCU • Technology transfer agreement between APS and NSLS-II is being worked out. • Flange-to-flange size is about 2m • LHe tank complies with ASME code

  16. Advantage of Nb3Sn Superconductor (LBNL-SCU) • Nb3Sn Undulators provide higher on-axis field when compared to NbTi undulators • Fabrication process is more complicated due to need for wind and react process for Nb3Sn • All materials have to be compatible with the high temperature heat treatment Undulator Field Strength Undulator Load Line Temperature Margin design point D.

  20. Magnetic Measurement System

  21. Budker Measurement (1) Superconducting Undulator Workshop, RAL,UK April 28-29, 2014

  22. Budker Measurement (2) Hall probes measurements setup Stretched line For Hall probe measurements Step motor Superconducting Undulator Workshop, RAL,UK April 28-29, 2014

  24. Magnetic Measurement System at ANKA

  25. ALBA Plan to measure ANKA Device Vacuum and thermal isolation will be assured through long bellows J. Company

  26. Summary • HEX-SCW can be located at 1m downstream from the center of the straight without significant degradation on beam dynamics. • We are currently receiving price estimate from potential contractors. • In-house magnet array fabrication requires some R&D funding/period. • Developing in-house magnetic measurement system is important to ensure that the ring will not suffer from any performance degradation by the SCW.
