5
Goals of the Single Undulator Test

• Provide critical input to the S/M system design
  reviews.
• Help to determine whether the support/mover
  system design is ready for final production.

6
Deliverables Single Test

• Measurement of cradle and rollaway motions
• Determine precision and reproducibility of
  motions, including start and stop
• Check for interference
• Measure vibration damping or (hopefully not)
  amplification.
• Measure position stability and temperature
  dependence of components and subcomponents.

8
Preparation _at_ ANL

  present thermal regulation is inadequate.
• Clean area
• Adequate space
• Experienced People
• Deliverables of the test are critical to our
  scope and schedule

9

  movers, Rollaway system, controls software and
  hardware

17
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

• Single Undulator Integrated System Test
• At ANL
• Prototype undulator no time for 1st article and
  no need
• Prototype support/mover system Cradle, CAM
  movers, Rollaway system, controls software and
  hardware
• Quadrupole with fiducialization surfaces

19
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
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
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
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
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 _at_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
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
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.
