  1. Injector Long-Lead Procurement PreparationD. H. Dowell, SLACLehman Review August 10-12, 2004 Description of the LCLS Injector Facility Accelerator Housing Sector 20 Alcove Summary of Major Acquisitions Brief Description of Major Acquisitions Conclusions & Summary

  2. LCLS Injector Configuration RF Gun Load Lock L0-1 & L0-2 3-m SLAC Sections Gun Diagnostics Laser Heater Transverse RF Cavity DL1 Bend Straight Ahead Spectrometer

  3. S20 Alcove Floor Plan • Title I Completed • Title II Specifications Released • Room & Utilities Sized for 2 Drive Lasers

  4. Major Long Lead Acquisitions • Drive Laser* • Drive Laser Diagnostics* • Streak Camera* • RF Waveguide System* • Cable Plant* • RF Gun and Load Lock* • Laser Heater Undulator* • L0 Accelerator Sections • Beam Transport • Magnet Power Supplies • RF Transverse Deflector *Over $100K

  5. Long Lead Injector Procurements Over $100K • Total LLP(FY05 TEC) is $12.7M =$6.7M(Labor) + $5.9M(Non-Labor) • Requires Purchasing Expediter & Combining Orders

  6. Drive Laser Architecture

  7. Drive Laser Procurement Process • Request for Information: July 2004 • Based on RFI the procurement strategy was changed • Processed Baseline Change Request (BCR) • Advanced Procurement Plan (APP) Required • Drive Laser Technical Review: July 21 • Responses Received from 5 Vendors: July 26 • Vendor Responses Consistent with Injector Cost and Schedule Baseline • Request for Proposals: September 2004 • Proposals Received: October 2004 • Evaluation of the Proposals (incl. presentations and technical review): October – November 2004 • Award of the contract: Dec. 2004 – January 2005

  8. Dual RF Feed Gun and Solenoid • Gun & Solenoid Engineering • will be Completed in September ‘04 • to Support Release of RFP • Dual Feed, Racetrack Shaped Full Cell • 120 Hz, 120 MV/m Operation • Cathode Plate Tuning • Design Should Accept Future Load Lock • SLAC/LCLS Specifies Cell Shapes • RF probes in both cells, 2-laser ports • Vendor Verification of Thermal Analysis • Standard Solenoid w/Field Correctors • Meet with Vendors Week of Aug 23

  9. Cathode Load Lock RF Gun Gun Solenoid Linac Solenoid L0-1 Porcupine Cathode Clamp Gun Spectrometer Low Energy Region of the Injector • Everything in FY05 • Except Load Lock Procurement in FY07 • Initial Gun Without Load Lock

  10. L0-1 Dual Feed Coupler • Dual feed RF design for L0-1 is finished. • Engineering design in progress • Internal technical review early September • Modify existing SLAC structure (in house fab) • Dual Feed, Racetrack Cavity Shape • Similar approach being used for gun • L0-2 is standard 3-m SLAC structure Design by Z. Li, SLAC/ACD

  11. Laser Heater (LH) Transverse RF Cavity OTR Emittance Screens DL1 Bend Straight Ahead Spectrometer Beamline Components • Quadrupoles from Xgamma Corp, • used at SLAC/GTF • DL1 dipoles designed (Build-to-Print) • Quotes (Build-to-Spec) received for • spectrometers & chicane dipoles • Linac Solenoid current in ANSYS & • Engineering Design • LH Undulator is low tech, • similar to SSRL design • Quotes rec’d for undulator • & chicane dipoles • Procure in FY06 due to • budgetary constraints

  12. Injector Design and Procurement Summary • Drive Laser • Received Budgetary Quotes from 5 Laser Vendors ($1M) • Procurement Plan In Process & Coordinated with Technical Reviews • RF Gun and Load Lock ($172K for gun only, $155K for Load Lock, $42K for RF Isolator) • SLAC Performed 120 Hz Thermal Analysis • Currently Requesting Bids for Vendor Engineering and Fabrication • SLAC Definition of RF Design and Vendor Engineering & Fabrication • L0 Accelerator Sections • L0-1 has Newly Designed, Dual RF Feed ($97.8K, in-house engineering & fab) • L0-1 Fabricated at SLAC by Modifying Existing SLAC Structure • L0-2 Standard 3-m Structure from SLAC Inventory ($54K, in-house engineering & fab) • Beam Transport • Purchase Standard Gun Solenoid but with Field Correctors ($32K, build to print) • Quadrupoles are Based Upon GTF Designs, but with 1” Dia. Aperture ($74K, build-to-spec) • DL1 Dipole Designs Completed and Will Submit to Vendors for Quotes ($49.5K in-house eng & fab) • Bids for Spectrometer and Chicane Dipoles Combined ($143.7K labor, $40.9K non-labor) • Linac Solenoid Currently in ANSYS and Engineering Design ($20K, build to print) • RF Transverse Deflector • Reuse Existing Structure in Linac ($34.5K labor, $19K non-labor) • Need to Evaluate Condition and Get Permission to Remove • Diagnostics • Purchase Bergoz ICT’s and Readout Modules for Charge Measurements (ICT’s are $15K/ea*5=$75K) • Use Standard SLAC Striplines for BPM Measurements, but Require New Large Dynamic Range Electronics (21 BPMs*$9K/BPM=$190K+Electronics) • OTR and YAG Profile Monitors With Wake Field Mitigation ($144K labor, $163.2 non-labor) • Integrated YAG/Faraday Cups Based Upon GTF Design ($23.5 labor, $20.6 non-labor)

  13. Injector Long Lead Procurements Summary • Procurement processes have begun for Drive Laser & RF Gun. • Engineering in Progress to Support Procurements. • Ready to Order Major Systems in Early FY05.
