Recent Significant Changes

DiagnosticsDescope

Wires ScannersOptical transition radiation monitors

RescopeEnd-of-undulator diagnostics

Reduced in value and moved to John Arthur’s discretionDetails of what we build still need to be worked out

Anticipate some savings of the Hydrostatic Level System

Scope AddedBeam Finder Wire (33)

Will be used to locate the “loose end” of the undulatorWill also be used as a beam profile monitor

– metal shields (to be added soon)

Significant “Hot Topics”

RF Beam Position MonitorsEssential for effective operations

We must accelerate their development and completion

Single Undulator TestEssential to test all form and fit

ANL/SLAC IntegrationNeed to work more closely with SLAC to ensure

Smooth transfer of knowledge and equipment to SLAC

Clean development of assembly and installation plans


Milton

20 Feb. 2006

6 Month Look Ahead Plan/Goals

UndulatorFirst articles assembled, tested, and at least 1 shipped to SLACAssembly production begun by both vendors

Single Undulator TestCompleted but still available for testing purposes

Magnet Measurement FacilityBeing commissioned

Vacuum SystemMain chamber full scale prototype completeAll other major components prototypes near completion

DiagnosticsInjector test stand testing with beam through the rf bpm completedInstallation complete of the three bpm test and testing with beam imminentBeam loss monitor design and engineering in progressTesting of beam finder wire prototype completedEnd-of-undulator details fully understood and decisions made about scope

Integration, Assembly, and Installation PlanningRefined and ready to proceed


Milton

20 Feb. 2006

Further Look Ahead

We will be (we better be) delivering loads of undulators, supports, diagnostics, etc. starting very soon and continuing through all of 2007.It is going to get very busy in the magnet measurement facility.

All initial assembly is done there along with all measurements and fiducialization.Overall system integration and assembly planning and refinement are crucial.

We will have no time to waste

Installation in the undulator tunnel will begin roughly in June 2007 (15 months away)


Milton

20 Feb. 2006

Other Comments

It is imperative that weWork together as a team

Both within ANL and together with SLAC

Don’t reinvent the wheel if it is not neededLeverage what other people have done

Accept constructive criticismCommunicateMove quickly and without delay

Don’t let things linger

We want the ANL LCLS project to look like a model of how one effectively accomplishes a project

Effort Management

Comparison to the ANL systemANL system uses estimates generated in the middle of the month by each individualThis in turn is compiled by hand by a variety of people from secretaries to division HRThis information is then passes on to the individual division offices, compiled again by hand and then entered into the ANL HR accounting system

The LCLS uses approximately 50 cost codes and 4 ANL Divisions in 2 different ALDships

Needless to say the above method, handled differently by different divisions, different individuals, and different ALDships leads inevitably to errorsWe developed our own completely electronic system to provide a cross check to the official ANL system and manage/control our accounting
