1st Articles (See White’s Talk)
One each received from the two vendors
Initial Measurements and Tuning
x/y trajectories well under the 2 micron limit
RMS phase error well under the 10 deg. limit

Undulator Production
Mu-metal ShieldsWill be implemented to buck Earth’s fieldCurrently working out the tuning procedure and overall effectiveness
Go AheadWill be given shortly to the vendors pending overall acceptance
Production PlansExpect 10 to 15 complete by end of fiscal year

Single Undulator Test (See Pile’s Talk)
Phase IComplete assembly with either production or mock up in magnet measurement labFull fit up expected plan by the end of April
Phase IIComplete assembly with all production componentsTunnel mockup includedWill remain at ANL for refinement, trouble shooting, and value engineering

Vacuum System (See Walter’s Talk)Single Path Pursued
Our project management oversight group was adamant about not pursuing an alternate time.
Considered too costlyMake what we have work
Current focusSolve all issues
PrototypeFull length prototype expected late June early July completion
ScheduleStill considered an undulator system critical path item

RF BPM
First Prototype CompletedBench Measurements
No surprises
Installation for Beam TestPlanned to install in ITS by end of month
3 BPM TestPlanned installation mid to late summer
ScheduleStill considered an undulator system critical path item

Beam Finder Wire (See Walter’s Talk)
Excellent Progress
Testing of positioningExcellent results
5 micron repeatability
Expect PrototypeMid Summer

OTR S1Location
Near beam dump after analyzing magnet at 135 MeV point in linac
PerformanceSimilar to what ANL was designing for the undulator
PlanBuild what we had designed for phase I and test in operation
Improve design performance if warranted in the future

Beam Loss Monitoring System
Basic concept establishedDetails, however, are notSchedule
Not yet on critical path, but we clearly are falling behind on the plan
PlanGet an appropriate engineer and physicist on this
This has proven difficult to maintain

SLAC Work
Measurement Bench (See Wolf’s talk)ANL bench on loan for development of overall production measurement and tuning planPrototype undulator at SLAC
Magnet Measurement Facility (See Wolf and Pope’s Talks)
Building construction completedEquipment to move in in the coming weeksThis will be a busy place

Assembly Planning (See Pope’s Talk)
SLAC working closely with ANLThe SUT will be used heavily in refining overall assembly sequence
Component deliverySchedule and assemble being refined to match planned component arrivals
This is already forcing us to optimize our effort planning to improve the arrival timing

Summary
Things are getting excitingProduction undulators are starting to arrive and be measured
There is still much to be doneThere are a few kinks we need to work out
Eg. The beam loss monitor workWe must keep our eye on some key items
BPMsVacuum Chambers
But we still believe we will meet all our critical milestones while not compromising performance
