24. Beam Finder Wire
All production problems are resolved at this point, but we were somewhat delayed due to issues with repeatability, chamber coating, and electronic modules.
Two units that should have shipped last week are on the way to SLAC at this time.
Details in Dean Walters’ talk

25. Beam Loss Monitor
Five production BLMs will be used to protect the undulators by inhibiting beam bunches following an “above-threshold” radiation event.
A joint R&D effort is aimed at enhancing these 5 units to enable LCLS to track each undulator’s accumulated radiation dose.
Undulator protection is the highest priority. The BLM will be integrated into the Machine Protection System (MPS) and requires only limited dynamic range from the detectors.
Dose tracking will enable long-term magnet damage to be characterized, but requires a radiation detector with large dynamic range (order of 106) and sophisticated diagnostics hardware and software.
30 production BLMs may be built in FY09 if R&D is successful

CPR & Costs to go –
Generally in good shape. Some unplanned effort has been required in the last two months to solve problems and meet production schedules.
Most spares costs were moved to OPC. Final spares costs will be recalculated using actuals and any required adjustments will be made.
Green Sheet System
A Web-based, almost real time, method of managing Argonne-APS cross- matrixed effort – (up to 60 staff 18FTE’s/year)
ASK System
A Web-based method of managing deliveries and technical documentation. A dictionary/index style look-up system.

Summary
Almost all deliveries complete by July 2008!
Production BLMs? TBD (2009)
Argonne Construction team rolls off the project in July
Argonne Management team drops to half-time in mid-July, and rolls off the project in September.
FY09 – a small budget is included for installation and commissioning support
