   BEAM COMMISSIONING
Cornell
Bartnik A
      Gun, Injector Cryomodule (ICM), and Beam Stop (Complete)
This scope includes commissioning activities such as machine operation and minor maintenance to recover basic operation of the gun, injector, and beam dump subsystems, and test at KPP current. A
      Diagnostics Line (Existing but Relocated)
This scope includes commissioning activities such as machine operation and minor maintenance to determine the injector operating point, and optimize bunch properties. A
      Main Linac Cryomodule (MLC)
This scope includes commissioning activities such as machine operation and minor maintenance to verify that required MLC operating points can be reached with beam. A
      Fractional Arc
This scope includes commissioning activities such as machine operation and minor maintenance to verify FFAG magnets with beam, and any required splitter adjustment. A
      Single Pass, Energy Scan
This scope includes commissioning activities such as machine operation and minor maintenance to verify full arc beam optics and FFAG energy acceptance. A
      Single Pass, Energy Recovery
This scope includes commissioning activities such as machine operation and minor maintenance to reach KPP goals A
      Four Pass Energy Recovery
This scope includes commissioning activities such as machine operation and minor maintenance to push for UPP goals.

6. All costs were based on expert judgement
Basis of Estimate
All costs were based on expert judgement
Each commissioning phase has
2 operators, each with 1.5 shifts per day
8 hours budgeted klystron time / day
BNL visiting scientist covered outside project
Expected diagnostic/tech/SRF support from previous experience
Commissioning phase durations begin at a construction completion milestone and end at a required beam test milestone.

7. Cost Estimate Overview

8. Major Risks Construction delays lead to limited commissioning time
Mitigation
Flexible commissioning plan (delay some aspects, focus on key goals)
Reduce scope (less optics verification, end at KPP)
Cost / schedule impact
Increased labor (more shifts)
Permanent magnet damage by radiation
Test during first FFAG beam test
If beam is not in beam stop, only enable laser for diagnostic measurement
Time to remove magnet, re-shim or replace
Beam halo prevents KPP current
Large phase adjustment in splitters allows more flexible optics
Increase bunch rate (lower charge) for same KPP current
Simulations from known halo sources
Time for optics adjustment (trial/error), 1 week downtime for laser modification
