LCLS interface to SLAC I&C is critical The I&C reorganization will benefit LCLS
Based on August Bottoms-up ETC 34.6% of Base Cost (TEC) Complete Contingency 24.7% of ETC 31.4% of TPC Complete
Project Walk-Down - Injector • Laser installed, operating • 3 mJ in the UV (before pulse shaping) • RF gun running at 110 MV/m, 120 Hz • Power supplies tested with controls • Scanning wires tested with controls • Magnets delivered, measured • SAD draft internal review complete • Injector readiness review 31 October 2006
Injector/Linac Installation • Injector installation work OUTSIDE the linac tunnel • 1/2007 injector hardware systems checkout • Laser commissioning and pulse shaping continues during installation. Final alignment of laser requires installation of gun-to-linac hardware • Decision to delay Injector fabrication to permit BC-1 shutdown work- first electrons 3/2007, delayed 2.5 months • Adequate commissioning time to meet 2007 goals

Linac • BC-1 Staged in linac tunnel for installation • Waveguides for s-band, x-band structures in place • Some diagnostic devices may be late for shutdown- install in 1/2007 – 2/2007 • Key parts for vacuum chambers connecting LCLS to Linac delivered from LBNL • Special diagnostics devices will be installed after the completion of this shutdown, in 1- or 2-day accesses (three 2-day RODs)
Controls • Commissioning basics to be in place 1/2007 • SLAC expert has connected existing Linac software applications to LCLS • Modernization of applications delayed • MATLAB applications written by physics group
Undulator • Single-Undulator Test results show great progress • ‘Long-term test’ beginning at ANL, a continuation of SUT • Undulator vacuum chamber prototyping tests • Tests not complete yet • Preliminary survey of design alternatives underway • Magnet measurements at SLAC • Dover bench to “rough” measure the undulators • New Kugler system for undulator measurement has collected first data
Six undulators from Hi-Tech on the way to SLAC. 08/18/067 Production Undulators & 1 prototype at SLAC
X-Ray Transport/Optics/Diagnostics • Design for gas attenuator is maturing • prototype results very nice • Incorporate gas fluorescence intensity monitor in the middle of attenuator • Offset mirrors • Specification in preparation • Will be state-of-the-art, not beyond
X-Ray Transport/Optics/Diagnostics • Prototype gas attenuator cell tested at LLNL
X-Ray Experiment Systems • Layout of experiments influenced by recent thought within LUSI teams • Deflection of x-ray beam in FEE onto 3 paths • Soft XR physics, AMOP/XR Pump/Probe in NEH • Hi Energy Density Physics, XR Correlation Spectroscopy, and nanoparticle/molecular imaging in FEH
Civil Construction • Proposed construction schedule: • Beampath installation can begin November 2007 • Beam Transport Hall • Undulator Hall • Front End • Near Hall • Budget Authority fully utilized in 2007
Magnet Measurement Facility Beneficial Occupancy 14 April 2006
Sector 20 • Beneficial Occupancy 21 April • Installation underway in vault • tray • supports • floor
Research Yard Ready for Start of Beam Transport Hall Construction- 28 August 2006
PROJECT SAFETY EXPERIENCE TO DATE • Civil Construction: • 68 K Hours worked (09/30/2006) • Zero Injuries • LCLS Collaboration • 737 K Hours worked (09/30/2006) • 2 Lost Day Cases (Shoulder & back strain) • 136 Days Worked Without Injuries (since 05/11/2006) • Safety training is 92% (SLAC goal is 90%) • Safety Trg Assessments are 99% current Lost Time Injury Rate Note: Injury rates based on 200 K hours (100 man years) of effort.
Civil Construction Bids • Beam path – ETC $75M for subcontracts • Beam Transport Tunnel (BTH) • Undulator Hall, Beam Dump, Front-End Enclosure • Near Hall • X-Ray Tunnel, Far Hall • Awarded $63M • Bids in hand for additional $9M • Re-bidding remainder • Central Lab Office Complex (CLOC) Bids • Sum to $25.6M
Issues - Civil Construction • Bids for all civil construction were very unfavorable • Projected cost of Turner subcontracts summed to $100.5M ( incl. 2-story CLOC) • Only $67.3M was budgeted • Project had sufficient contingency to award @ up to $85.3M • Insufficient contingency to award CLOC construction
Civil Construction • LCLS Management forced to conclude that CLOC construction cannot go ahead at this time • It would be imprudent to retain the CLOC, as designed, in the Project plan – CLOC removed from EVMS • Insufficient contingency available to guarantee successful completion of the Project with this scope. • Turner Construction Co. and CLOC bidders have been notified of this decision. • Necessary contract modifications in preparation
Highly Volatile Market • Actual results for $5M buildings built at LLNL • Similarly spartan office buildings for project teams • Price is fixed, bidders propose square footage No award will be made
Civil Construction • Revision of LCLS plan for office/lab space • Too early to choose options • Re-examine needs and alternatives for meeting them • Base decision on available contingency • 10/2007 time frame
LCLS Space Needs • LCLS operational needs can be met by reallocation/rehabilitation of existing space at SLAC • To be presented to space planning breakout
Action Items from February 2006 • 15 June Mini-Review • 1st group of CF bids received, evaluation underway • Follow-up status check 29 August
Summary • Injector and Bunch Compressor 1 will be ready for commissioning in March • Preparations for commissioning the injector • Address engineering, physics, operations, safety • Undulator Systems - excellent progress • X-Ray Front End design maturing
Summary (continued) • Civil construction costs- cancelled CLOC award • NO COMPROMISE to capability of FEL • Contingency is satisfactory with CLOC award cancelled • Building the CLOC as-designed unrealistic • Revised LCLS space plan
