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

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

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

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
