3. Introduction
A detailed scope, cost and schedule estimate for installing and testing LCLS-II cryomodules (two-at-a-time) as an assembly in the LERF has been developed in response to possible LCLS-II project needs.
Estimate considers four phases of increasing scope - short term limited testing (microphonics & technical characterization) up to a full test bed (a possible mitigation for schedule recovery) to operate in parallel with the CMTF in the Test Lab.
Phase 1 – Set Up LERF for CM testing
Phase 2 – First pair of CMs - Initial Full Power Testing
Phase 3 – Three Production CM testing cycles
A typical test cycle is 5-8 weeks
Phase 4 – Restore LERF

4. Preliminary Detailed P6 Cost Estimate
Set Up
First Test
Three Tests
Restoration
Full cost recovery Including operating cost estimates for LERF
Operating costs - $10.8K/week while CM is cold
Path forward assuming JLab approval
Proposal brought into the LCLS-II project baseline via baseline change request – expect some minor cost adjustments
Subsequently managed using EVMS to monitor and report on progress

9. Developed a p6 what-if file for the scope of work
Schedule
Developed a p6 what-if file for the scope of work
Assumes early start of all activities for Phase 1
Results in labor “bump” early
Plan to refine based on FY2018 plans (and acceptance of this proposal)
Adjust labor to spread over 11 months rather than 8 months – more confidence in hitting date in Jul-2017
Bayonet box design decouples transient operations
May be able to add testing cycles if not limited by CEBAF run program
REV2, 03-AUG-2017

10. Assumptions Priority for JLab is 12 GeV Operations
Schedule for testing CMs will be coordinated with FY2018 & FY2019 run schedules
CM testing windows will be adjusted to minimize impact on NP program
Full cost recovery from LERF operations is required
Defined boundaries between laboratory program and WFO
Cost includes specific LERF facility charges
Draft cost and schedule presented in parallel to LCLS-II and JLab management.
Updates and revisions based on discussions are included
Staffing requirements will be considered as part of overall FY2018/2019 laboratory planning. Priority consistent with WFO vs. CEBAF operations.
Recommend meeting with LCLS-II Project Director, Lab Director and Chief Planning Officer to review and discuss overall plan

11. Impacts & Risks
Cryogenics: present 2K issues complicate near term scheduling. Contamination is a concern that could affect availability.
Can’t stab U-tubes during CEBAF ops (need 4K for 1 week)
Repeated stabbing adds potential contamination problems
Cooldown and warm-up : overall cryo load must be handled properly with controls.
CEBAF Operations:
Phase I no impact.
Phase II & III requires PSS Control and interface. Cannot keep two of the FEL CMs cold as CEBAF spares. Coordination is required with other cryo activities.
Phase II & III need coordination with CEBAF 12 GeV operations.
LERF Operations: Phase II and Phase III would eliminate all other LERF operations.
Staffing: Initial plan utilizes combination of in-house staff and possibly term hires. Higher priority work might limit available staff.
Schedule: Working towards July test cycle (April if all goes very well.)

12. Ready for BCR proposal to LCLS-II
Summary
Detailed costs have been presented for the scope associated with testing LCLS-II CMs in the LERF
Costs are part of an integrated preliminary proposal that includes cost & schedule details
Ready for BCR proposal to LCLS-II
Some minor updates/modifications may be needed based on feedback from this review

13. Back Up
REV2, 03-AUG-2017

14. Phase I – Configure LERF for Testing
Removal of 20’ of back leg of existing machine to install/position CMs
Removal of u-tubes from two existing CMs in FEL vault
Can remove two high performing CMs to augment CEBAF
Requires a set of u tubes to connect CMs to existing cryogenic transfer line bayonet connections
Review design; procure cryogenic hardware
Requires one set of CM testing end caps (same design as CMTF)
Requires two sets of stands (same design as CMTF)
Requires one set of interconnect hardware including HOM BLA, bellows
Install cryogenic controls (Cryocon temp readbacks, heaters, JT and cooldown valves, etc.)
Pull cabling
Install SLAC-provided SSAs and HPRF hardware
Install SLAC-provided LLRF controls
Review and approve any updates to OSP for FEL vault operations
Decarad and Faraday cups for radiation monitoring
REV2, 03-AUG-2017

15. Phase II – Initial Full Power RF/Cryo Testing
Assumes all hardware from Phase I available
Schedule allows for more time and resources for initial testing cycle
Install pair of CMs in LERF
Connect RF, instrumentation and cryo controls
Coordinate cooldown with CEBAF operations
Evaluate procedures for cooldown, RF testing and warm up
Coordinate warm up with CEBAF operations
Remove pair of CMs from LERF
REV2, 03-AUG-2017

16. Phase III – CM Acceptance Testing
Assumes Phase II completed
Schedule considers logistics for installing multiple CMs in LERF vault
Staffing estimate will be based on current project baseline
Assumes one test cycle in CMTF / 5 wks
Potential impact - CMTF & LERF testing is conducted in parallel
REV2, 03-AUG-2017

17. Assumes Phase III completed
Phase IV – Restore LERF
Assumes Phase III completed
Remove any LCLS-II specific hardware from vault
