  1. Proton Improvement Plan (PIP) William Pellico PIP and MI 700 kW review 21 – 22 January 2015

  2. PIP – Talks will address the following topics • What are the goals, deliverables, budget and schedule of the PIP project? Are they properly defined, well understood, achievable and self-consistent? This Talk • Plans to address the Linac vulnerabilities and reliability adequate? (Fernanda Garcia Talk) • Are the plans for the Booster RF cavities sufficient to extend their life at least until 2030? (CY Tan Talk) • Are the plans to minimize Booster losses adequate and sufficiently understood to allow for the planned higher beam power levels? (Keith Gollwitzer Talk) • How well do the current plans for PIP integrate into future plans for achieving even higher power (PIP II & Beyond)? (Steve Holmes Talk) . W. Pellico: PIP and MI 700 kW Review

  3. PIP = Campaign to improve the Proton Source • Aligned to AD operations and resources • Official start date FY12 • An initial total budget of ~90 M dollars largely over 5 years • A small number of activities have been extended • Adjustments to resources • Alignment to program planning (ex. reduction of klystron installation) W. Pellico: PIP and MI 700 kW Review

  4. The Proton Source is comprised of three accelerators and several beam lines. • Pre-Accelerator • Under PIP – upgraded to an 750 KeV RFQ based H- injector • Began as a 750 KeV Cockcroft-Walton (CW) & Proton Source 1969 • Switch to H- sources in the 1970’s • Linac • 750 KeV to 400 MeV H- accelerator ( 200 MHz DTL, 805 MHz SCL) • Originally 200 MeV extraction – till 1995 • Booster • 15 Hz Synchrotron • 400 MeV to 8 GeV • Designed originally for 200 MHz to 10 GeV but operated at 8 GeV ext. • Extraction Lines 400 MeV, NTF, 8 GeV Beam Dump, (Muon Test) W. Pellico: PIP and MI 700 kW Review

  5. Pre-Injector Upgrade – RFQ Injector Line (RIL) PIP’s first big success • FNAL considered using RFQ in late 1980's • BNL and FNAL worked with LBNL on a RFQ design • 200MHz built for BNL but FNAL cancelled order • FNAL initiated the Pre-injector upgrade in 2008 • Fermilab retired C-W in August 2012 after 43 years • of operation • FNAL Pre-injector upgrade commissioned in Dec 2012 • Delivered beam on schedule New RIL The new RIL fit into the existing CW area. W. Pellico: PIP and MI 700 kW Review

  6. Linac Overview 400 MeV NTF 750 keV 1 Tank 2 Tank 3 Tank 4 Tank 5 0 M1 M2 M3 M4 M5 M6 M7 Designed for high intensity single shot proton injection 7835 7835 Socket High Energy Tunnel High Energy Linac Gallery W. Pellico: PIP and MI 700 kW Review

  7. Introduction to FNAL Booster Synchrotron • H- ions are stripped and multi-turn injected onto the Booster • Protons are accelerated from 400 MeV to 8 GeV in 33 msec • Fast cycling synchrotron • Fast magnet ramping • Frequency of 15 Hz • Single turn extraction Linac Beam Combined Function Magnets No failures after initial phase… But 8 spares have been refurbished… W. Pellico: PIP and MI 700 kW Review

  8. PIP Introduction The viability of the US domestic experimental High Energy Physics program for the next ~15 years depends critically on the performance of the Linac and Booster accelerators. • FY12 PIP Organization and Task Structure Developed • An operational campaign with project like structure/controls • Resource Loaded Schedule (RLS) • Work was prioritized based upon resources and program planning • Management Organization • Document and Resource Controls • Web page with links to all documents http://www-ad.fnal.gov/proton/PIP/PIP_index.html • Regular management meetings, PMGs, reviews and reports…. W. Pellico: PIP and MI 700 kW Review

  10. PIP Goals and Scope (Provided in 2011 – Directorate S. H. / DOE Talk ) • Goals: Specific to the issues surrounding the FNAL Proton Source • Increase the beam repetition rate from the present ~7 Hz to 15 Hz • Eliminate major reliability vulnerabilities and maintain reliability at present levels (>85%) at the full repetition rate • Eliminate major obsolescence issues • Increase the proton source throughput, with a goal of reaching > 2E17 protons/hour • Ensure a useful operating life of the proton source through at least 2025 • Scope: • Upgrading (or replacing) components to increase the Booster repetition rate • Replacing components that have (or will have) poor reliability • Replacing components that are (or will soon become) obsolete • Studying beam dynamics to diagnose performance limitations and develop mitigation strategies • Implementing operational changes to reduce beam loss W. Pellico: PIP and MI 700 kW Review

  11. PIP Goals: Plan elements can be categorized into three areas: But many have significant overlap. Reliability Viability Flux Instrumentation RFQ Injector Booster Notcher Dump Linac Notch Shielding Anode Supplies Cavity /Tuner Refurbishment Cogging Linac RF Power Beam Physics New Booster Cavities Linac Modulators LCW Work Solid State Upgrade Aperture Work Vacuum Systems New Tuners Dampers Bias Supplies Spare Cavity Perpendicular Cavities Utilities Power 15 Hz Operation W. Pellico: PIP and MI 700 kW Review

  12. PIP has 32 Tasks (New Cavity being split)16 are completed and closed 6 more tasks will be closed in FY15 PIP – Task Structure CY Tan Talk Fernanda Garcia Talk Keith Gollwitzer Talk Completion of all cavities likely into FY16 Completed Being split into three parts to better align with PIP II FY15 W. Pellico: PIP and MI 700 kW Review

  14. Beam Operations PIP started Booster Loss profile - no longer loss limited Proton Plan: Collimators Correctors Beam dump Loss Limited until 2010then cycle rate limited W. Pellico: PIP and MI 700 kW Review

  15. FY15 Proton Delivery Scenario (approximate, no shutdowns shown) PIP – Flux, Uptime & Viability W. Pellico: PIP and MI 700 kW Review

  16. PIP schedule and resources As part of operations – PIP needs to adjust to changes in resources, priorities and ongoing operations. Therefore Pre-Acc, Booster RF and fully engineered systems were the first tasks to be addressed. W. Pellico: PIP and MI 700 kW Review

  17. PIP - Work Prioritized • Booster solid state – completed on schedule (FY13) • Booster 15 Hz operation – • Refurbishment (on schedule FY15) • New Booster Tuners (10 to 20 in FY15) • Long lead task items – define/initiate necessary work to meet schedule • Linac RF power systems (7835 Tube risk/replacement option) • Linac modulator (obsolete tubes and reliability) • New Booster Cavity (Several Independent Tasks) • Booster shielding (Completion in FY15 – before high flux operations) • Beam Physics • Booster absorber system (Completion this shutdown) • Aperture/Alignment (Completed FY14 – may look again under operations) • Cogging (Slated to be completed this month) • Linac Laser Notcher (Installed mirror/vacuum cavity) • Recently successfully tested laser power levels and cavity • Booster RF Systems (Anodes, Bias Supplies– completion in FY15) • Instrumentation/Diagnostics (Linac/BoosterBPMs, Dampers) • Utilities (House Power, LCW, Vacuum- determined by shutdowns) • Linac utilities completed FY15 Blue: significant progress Purple – to be completed Green: completed W. Pellico: PIP and MI 700 kW Review

  18. Scope change to PIP 2014 Modifications to PIP objectives that reflect present laboratory planning. This letter from Sergei has been added to PIP docs and reflected in PIP planning. Extend Boosteroperations to 2030 Linac Operations until 2023 Consider transition to PIP II W. Pellico: PIP and MI 700 kW Review

  19. PIP Planning – Near Term vs. Longer Term • Get to 15 Hz • Increase Flux • Loss Control • Shielding • Beam Physics • Reliability • Viability • New – PIP II interface • RLS changes in progress • PIP was planned to be a ~5 year campaign: Why? • Due to fact that after NOvA and BNB (as well as Muon/G-2) would require more flux than the PS could deliver – required a rapid response (near term). • Additionally, the PS would need to keep running reliably for 15+ years required a long term strategy. W. Pellico: PIP and MI 700 kW Review

  20. PIP-II impacts The Original PIP (Integration talk by S. Holmes) • Anticipating a PIP-II Linac in 2023 • Linac needs to operate until 2023 • Booster needs to operate until at least 2030, and be able to accept the PIP-II beam in 2023 • Meetings and studies underway to adjust the PIP plan for PIP-II • Some changes made immediately, expect plan to fully settle mid-2015 • Implications: • Klystron implementation on hold until need is demonstrated • Prototype will be completed and tested to spec • Booster cavity strategy evolving • Any full replacement to be compatible with PIP-II and later upgrades • Requirements to be settled upon in the near future • Booster modifications to allow 800 MeV injection • Booster 20 Hz operations will be studied • Booster infrastructure Working to integrate into PIP or operational effort – depending on timetable/funding W. Pellico: PIP and MI 700 kW Review

  21. PIP Gantt (As presented at AAC FY13 & FY14) Completion Date Base Lined PIP Not practical under PIP IIchanging scope Removed Being Split PIP II alignment Required for 12 Hz Required for flux Required for 15 Hz Required for reliability 2012 Gantt in blocks, AAC Feb. 2013 black arrows and ACC Oct 2014 with red dots W. Pellico: PIP and MI 700 kW Review

  22. PIP Gantt (being updated to reflect PIP II/P5/ab goals) PIP started out as a 5 year plan: 2012 to 2017 Modified due to changes in resources and now to changes in program. All of PIP completes in 5 year window except for two tasks: Booster Cavities & Linac 200 MHz RF PS. W. Pellico: PIP and MI 700 kW Review

  23. PIP key milestones to date Work in Progress Shutdown Dependent W. Pellico: PIP and MI 700 kW Review

  24. PIP End of FY14 Budget and Labor Summary (example) PIP has been largely an AD effort, however TD has and will continue to be a critical part. CD has and will be required in some beam physics as well as FESS for Booster feeder and sump work. W. Pellico: PIP and MI 700 kW Review

  25. PIP – Updated Budget PIP new guidance was recently provide and shown below – an updated schedule will reflect funding/work plan. The alignment will result in a final cost for PIP going from ~90 M$ to ~78 M$. Klystrons removed Items not originally include in PIP but now being put into the plan: Booster Feeder (working with engineering on options) Booster Sump (selected failed units and discharge system) W. Pellico: PIP and MI 700 kW Review

  26. PIP – Outlying years M&S allocation (FY15 to FY19) Linac 6 Modulators Utilities Infrastructure High Level (Klystron) Completion of Prototype Booster Completion of Anode(s) Completion of Bias Supplies New Tuners Cavities Two additional re-worked cavities New PIP II aligned cavities Perpendicular Cavities Completion of BPMs Beam Physics 44 M$ to completion W. Pellico: PIP and MI 700 kW Review

  27. Conclusion • PIP has been going strong and is now past the midway point. • 15 of 32 PIP tasks have been successfully completed with 6 more on schedule to be completed this FY. • Most of these tasks followed the initial schedule provided in the FY12 (all while adjusting to labor and funding modifications) • When complete all but two (Linac DTLs and Booster gradient magnets) of identified concerns of the PS will be mitigated. Spare Booster gradient magnets have been reworked and readied for use. DTLs themselves should not pose an issue - but old components remain part of the system. • The upcoming of PIP is critical, 15 Hz operations and flux ramp up, and will require a lot of hard work. FNAL and especially AD management understand importance of PIP and look forward to positive results. • Thanks to BNL, SLAC and LANL for support……. W. Pellico: PIP and MI 700 kW Review
