Next Steps for the Proton Driver?

• System Demonstration of Fast Ferrite Phase
  Shifter
• Proof of Principle already in hand
• Other High Priority Tasks
• RD on the PD Front End at SMTF
• 1300 MHz Cryomodules at FNAL
• Main Injector Upgrade Plan
• Complete Publish the Linac Design Report
  Physics Documents
• Work towards becoming a Project
• Create and Staff Project Office
• Generate the required Documention for CD-1 and
  beyond

325 MHz PD Front End at SMTF

• Why is this important?
• Demonstration of Phase Shifters with Proton Beams
• Key Technical Demonstrations
• 1 Klystron driving many loads
• Pulsed operations of SCRF Spoke Resonators with
  beam
• Success ? reduction of downstream mitigation
  costs (debuncher, collimation, phase shifter
  bandwidth)
• What is required?
• 325 MHz RF Station (now in progress)
• Complete Accelerator Physics Design
• Copper Front End
• First SCRF Spoke Cryomodule

Tasks Assigned Responsibilities

• 325 MHz RF Station
• Build Modulator (Jensen, Pfeffer, Wolff
• Klystron (A. Moretti young blood)
• Klystron Controls (H. Edwards standing army)
• 325 MHz RF distribution
• Passive Fanout (R. Kustom, Al Moretti, young
  blood)
• IQ Modulator Boxes (Ding Sun)
• Phase Shifter Drive Electronics (S. Hays, O.
  Payne)
• 325 MHz Coax Shifters (Handoff from Dave Wildman)
• LLRF
• Hardware Platforms(s) (SNS, DESY, ILC?)
• Proton Simulations ? FPGA Code (big effort)
• Ion Source LEBT
• Clone SNS or DESY H- Source (collaborations
  ongoing)
• RF Quad
• CAD files for JPARC SNS in hand- decide which
  to clone
• MEBT(G. Romanov, D. Chichili)
• Same Technoology as RT-TSR Beam Chopper can be
  deferred
• RT-TSR (F. Nobrega, M. Popovic, )

PD Front End

Near-Term PD Front End RD

• Goal is to be able to run 325 Klystron into RF
  split, 1-2 channels of IQ modulator Box, and a
  couple of copper cavity loads shortly after
  Klystron arrives this winter.
• March 325 MHz Klystron Purchase (in progress)
• April Ion Source RFQ design decisions
• May AP Design Frozen after Workshop
• June Order or Begin fab of 1st 325 Spoke Cavity
• July First full-spec IQ modulator box
• August Cold Test of RF Split
• November First Modulator Construction complete
• December Klystron Delivery Commissioning Start
• Requires Klystron Controls and Skeletal LLRF

1300 MHz Cryomodules at FNAL

• Fully Integrated Effort with ILC _at_FNAL
• Convert TTF drawings and start ordering parts
• Copy DESY infrastructure, tooling, clean rooms
• Rely on commercial/collaborator cavity processing
  
• Collaborative relationship to ILC should become
  more clear now that GDE exists.
• Key Milestone for PD Infrastructure capable of
  final assembly of 1 Cryomodule/month at FNAL and
  collaborating Labs.
• Short term milestone Resonance control of 1300
  MHz cavity at A0 with fast phase shifter

Main Injector Upgrade Plan

• Neutrino physics opportunities are leading to an
  aggressive plan for MI upgrades (Proton Plan)
• Many aspects of the Proton Plan plan are very
  good news for the PD
• Large aperture quads, gamma-T jump, collimation
• The RF system is the most expensive upgrade
• Exploring two alternatives
• (Proton Plan) 2-tube upgrade (limited performance
  but faster?)
• (Proton Driver) new cavity upgrade (Designed for
  full PD beam)
• Finish prototypes, document plans, capabilities,
  cost
• Decide which way to go by end of year.

Project Office

• Transition from CD-0 to CD-1 requires this be
  created and staffed
• The Project Management Activities include
• Scope Definition
• Technical Plan (CDR)
• Cost Estimate and Control System
• Project Integration Schedule
• Quality Assurance
• Human Resources Management
• Project Communication
• Risk Management Contingency Estimates
• Procurement Collaboration Management

9
Project Office

• Immediate need for
• Detailed technical integration
• Formalization of risk and associated decisions
• Value engineering
• Negotiation with potential collaborators
• Assembly of integrated cost / schedule
  information
• Definition of sub-project scope(s) and associated
  delegation of authority
• Planning and control
• Iteration, negotiation, discussion, review with
  the laboratory, collaborating institutions, and
  funding agencies
• We are well along at defining the Project
  organization and identifying key personnel

10
Collaboration

• Lots of opportunity for collaboration
• Some Early Examples
• ANL Collab on Accelerator Physics Spoke
  cavities
• SLAC Collab on Modulator IGBT switches
• BNL (informal) collab on 8 GeV Transport issues
• FNAL will work closely with ILC GDE leadership to
  make the synergy with ILC a reality.

11
Time Line

• Approach to Schedule is Aggressive
• Opportunities in Neutrino Physics drive schedule
• Starting assumption is a 4-Year construction
  period, starting in FY08
• Process will include
• Complete Technical Design
• Laboratory, HEPAP, DOE Approval Process
• Environmental Requirements (permits)
• Detailed Project Planning
• Funding Approval

12
Conclusions

• We have presented a Proton Driver conceptual
  design that is both technically and financially
  feasible.
• We have a near term RD Plan that will quickly
  resolve the remaining technical issues.
• We have a plan for the formalization of the PD
  Project that will clean up many of the remaining
  rough edges.
• We believe we can achieve our goal of a rapid
  project approval and construction start.
