Safety Minute
Even though you wear your PPE you’re not always as safe as you might think. This
guy is wearing his face mask while arc welding. In this case, it’s almost as useful
as an ashtray on a motorbike.
Two really important
statements –
1. Never Underestimate
the Power of Co-incidence
(There could be more safety issues
less obvious than the one you are
trying to negate)
2. ISM – Do what you say
you do!
Define the scope
Analyze (ALL) hazards
Develop/implement controls
Perform the work within
controls

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.

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 ArgonneAPS cross- matrixed effort – (up to 60 staff 18FTE’s/year)

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 halftime in mid-July, and rolls off the project in
September.
FY09 – a small budget is included for
installation and commissioning support
