White Undulator System Testsmwhite@aps.anl.gov 07 April 2005 LCLSLCLSLCLSLCLS Use of Substitute Units The quadrupole, BPM, and vacuum chamber will be same-size and same-weight fiducialized substitute units when prototypes or first articles are not yet available. Pumping crosses and pumps will be used Cabling will be incorporated Magnet water piping will be incorporated “WPM, HLS, BLM sensors” will be incorporated Some kind of Earthquake bracing will be determined in collaboration with the SLAC safety committee, and will be incorporated; it will probably not be the final system

19. Marion M. White Undulator System Testsmwhite@aps.anl.gov 07 April 2005 LCLSLCLSLCLSLCLS Fixed Support ANL assumes the Fixed Support scope: we are working toward having a prototype ready and instrumented for the Fall 2005 tests. Availability of FS prototype permits monitoring its behaviour as well. If unavailable for the single test, a solid backup support will be used

20. Marion M. White Undulator System Testsmwhite@aps.anl.gov 07 April 2005 LCLSLCLSLCLSLCLS Schedule: Single Undulator Module Design/procure vacuum/diagnostic components: starts next week Develop detailed plan and fixed-base design. Start June 05 - engineering specs well in hand then. Prepare controls HW/SW Jun-Aug 05; debug Prepare test area – Jun-Aug 05; monitor Prepare/fabricate test stand and components August thru November 2005; Assemble Components latest December 2005 Short term test complete by mid-January 2006; leads to FDR; 2-month test continues after that.

21. Marion M. White Undulator System Testsmwhite@aps.anl.gov 07 April 2005 LCLSLCLSLCLSLCLS Prototype Undulator scheduling Design, instrument, and verify shipping container Ship prototype undulator to SLAC in the June 05 timeframe for setup and integration of MMF instrumentation and systems. SLAC ships prototype back to ANL for assembly into single-module test.

22. Marion M. White Undulator System Testsmwhite@aps.anl.gov 07 April 2005 LCLSLCLSLCLSLCLS The Two Tests: Multi Two (or three) undulators with long and short breaks will be mounted on fixed supports Ideally, includes wire position monitor segment and hydrostatic level – at least the mountings and sensors. Contains production first articles. verify form and fit of all subcomponents, Refine assembly procedures Assist in development of maintenance procedures Refine alignment and realignment procedures

23. Marion M. White Undulator System Testsmwhite@aps.anl.gov 07 April 2005 LCLSLCLSLCLSLCLS Multi-Undulator Test Can be done at ANL or SLAC First article undulators and subcomponents will be available at ANL after acceptance verification. Stable area @APS Initial assembly and testing will take place at ANL; then ship to SLAC for long-duration testing at MMF. SLAC personnel would participate in the testing and analysis, and would learn first from experienced ANL personnel. Schedule is dependent on preparing the area and on first article delivery schedules; follow-on to the Single-module test. First 2 undulators available by 3/06.

24. Marion M. White Undulator System Testsmwhite@aps.anl.gov 07 April 2005 LCLSLCLSLCLSLCLS Deliverables Everything from the single-module test plus: validate relative motion and alignment between two modules and stability Additional software - development and debugging verify no constraints from final cabling and earthquake bracing

25. Marion M. White Undulator System Testsmwhite@aps.anl.gov 07 April 2005 LCLSLCLSLCLSLCLS Summary A test of a single-undulator-module assembly will be carried out at ANL in Fall/Winter 05 using prototype and substitute components to provide critical data for the support/mover system final design review prior to RFP. An integrated multi-undulator-module assembly will be done when first articles are available, testing component fits, verifying assembly and installation procedures, verifying relative motion and motion limits, and monitoring thermal and vibration stability.
