Commissioning
Begins after all components have previously been installed, aligned, connected, and verified by installers
Commissioning :
Pre-Beam Checkout
Final component verification, made mostly in tunnel by system physicist ( e.g.
, polarities, motion-control, etc.)
Systems validation ( e.g.
, power supplies, software applications, etc.)
Beam Commissioning
Component and system verification/calibration with beam
(hardware and software; e.g.
, BPM tests)
Optimization of beam transport and tuning ( e.g.
, steering)
Characterization of beam quality ( e.g.
, emittance meas.)

Commissioning Plans - Preparation
Plan development assigned to each system team:
Drive Laser (White, Gilevich)
Gun & Injector (Dowell, Limborg, Schmerge)
Linac (Emma, Wu)
Undulator (Nuhn, Welch)
FEL (Welch, Nuhn)
XTOD/XES (Arthur, M öller, Stefan, Tompkins)
Each developed an MS-Project file detailing both schedule and strategy
Goal was to force early development of tuning strategy
(what to measure, what to tune, in what order – simulations encouraged now)
Files now merged into master file and time-frame locked to project schedule (thanks to Jim Welch)

John N. Galayda galayda@slac.stanford.edu

Preparations for Accelerator Readiness Review
Integrated with design review process
Component and System PDRs and FDRs are being conducted following LCLS guidelines.
Safety aspects are a normal part of the technical requirements.
Working to report safety analyses in a uniform way to facilitate future assessments.
SLAC Citizen’s Committees participate in the review process, following normal SLAC practice.
Citizen’s Committees involvement specified through the SLAC
Safety Oversight Committee.
Need to ensure that all aspects of the project are reviewed, and that the completeness is presentable in a coherent way.

John N. Galayda galayda@slac.stanford.edu

Accelerator Readiness Review
LCLS ARR for Injector Commissioning will take place Sept.- Nov. 2006, once Citizen Committees’ reviews are complete and the SOC is satisfied.
Working with the DOE SSO to ensure that the review process outlined here will be appropriate.

Project Highlights and Key Considerations
Conventional Facilities
Architectural design @ 100%
Construction manager on board
Bids for first major packages in hand
Second group of bids due 14 June third group of bids (for CLOC) due in September
Beneficial occupancy of entire e-beam path and NEH by August 2007

John N. Galayda galayda@slac.stanford.edu

First Bid Package – Entire Beam Path
Bids higher than estimates
Considerable draw on contingency required
Various alternatives under consideration
Changes to beam path, halls and FEL commissioning schedule are NOT under consideration
Economies required to deliver 2-floor CLOC
