  1. Run II Upgrades Status October 2005 Report& V4.0 Project Plan Pushpa Bhat

  2. Outline • Status Report for October ‘05 • % Complete • M&S Costs • Effort Report • Version 4.0 (v4.0) Project Plan • Scope Changes • v3 vs v4 comparisons • Change requests • Contingency Analysis

  3. October Status (v3 plan) 89% due to shutdown postponement Not re-baselined with new dates With v4, Nov. status ~80% complete,~100% A/P

  4. M&S Spending

  5. Effort Report

  6. Version (v4) PlanScope/Schedule Changes from v3

  7. Upgrade Status in a nutshell • 76% complete as of Oct. 31, 2005, as statused w.r.t. v3.0. • 82 of the 106 A,B,C milestones met • Major tasks : Tev alignment, helix/separators, Tev BPM and many other Tev instrumentation, MI RF upgrade and slip stacking, MI dampers, AP2/DB aperture improvements, AP2 instrumentation, new Li lens, Recycler and e-cool commissioning and integration. • Graduated • Phase-1  Phase 2 with slip-stacking • Phase 2  Phase 3 with e-cool in HEP (defined as in v4) • v3v4: Phase 3, 4 redefined; One major scope deferred (Stacktail bandwidth upgrade); one canceled (TEL3); minor new scopes to be added; new shutdown dates and re-baseline

  8. Redefining Operational Phases • V3: • Phase 2: After slip-stacking  current phase • Phase 3  e-cool for HEP + tank move • Phase 4  bandwidth upgrade +helix • V4: • Phase 3  Integration of e-cool for HEP • Started on October 1, 2005 • Phase 4 : First phase of stacktail upgrade • tank move when we reach stack rates that would require it • Milestone date in v4: 6/13/06 • Defer work on Stacktail bandwidth upgrade • Decision milestone in summer ’06 (mid-July ’06) • back from shutdown in June • Phase 5: bandwidth upgrade and complete remaining pbar aperture +Tev upgrades

  9. Scope/Schedule Changes • MI8 BPM Upgrade • New scope (Cost increase: M&S $98K, Labor: $60K) • Upgrade BPM electronics in MI-8 beamline to help improve performance for slip-stacking operations; new BPMs along with MI8 collimator. (New BPM system similar to new transferline systems under rapid transfers). • Pbar target upgrade • Additional scope • No additional costs; Cost transfer from previously completed tasks on pbar target and beam sweeping • Upgrade pbar target design with improved cooling and motion. Prompted by concerns about target damage in stainless steel and inconel targets in recent operations • Optical Transition Radiation Detectors • Revised scope (No new cost changes) • Detector construction & tests completed. Maybe installed in the Tev this weekend. Installation commissioning to be handed over to Instrumentation Department.

  10. Scope/Schedule Changes • Li Lens • Revised scope, Schedule Changes • Class A milestone Li Lens operational redefined. • Work on prototype-2 was delayed due to change in priorities. Prototype-1 lens (8 mm dia vs 10 mm for PT-2) has been used in operation since 8/1/05 • V4: Li lens operational Class A milestone met 8/15/05 • PT-2 lens to be completed summer ’06 • Fabrication of lenses transferred to the pbar source department after successful evaluation of PT-2. • Accumulator Stacktail system upgrades • Deferred Scope • Stacktail Upgrade: Pause work and include a decision point to proceed or not in mid-July ’06; implement tank move when stack rate/flux warrants it; install full upgrade in ’07 if required  major component for Phase-5.

  11. Scope/Schedule Changes • Pbar Stack Rate Task Force • New Scope (Cost increase: M&S $200K) • Task force under McGinnis for beam-based alignment and aperture improvements throughout the pbar source. For any new diagnostic or instrumentation that might be needed by the task force. • Rapid Transfers (schedule change) • Was tied to shutdown ’05 • Class A Milestone slipped from 10/31/05  2/24/06 • Additional Recycler upgrades • New Scope (Cost increase: M&S $200K, labor $220K) • Upgrades/rebuilding of the power supplies to the Recycler correction elements. The Recycler has lost 8 out of 12 stashes due to failure of the dipole corrector power supplies. The supplies are from the Main Ring and are at least 15 years old.

  12. Scope/Schedule Changes • Additional e-cool System Upgrades • New scope (Cost increase: M&S $165K) • Upgrade Electron Cooling SF6 Gas Recirculation System. The current system was designed for the R&D phase at wide-band Lab. A recent review has concluded that for routine reliable and safe operation, major components of the recirculation system be replaced with an all-in-one skid. • Miscellaneous e-cool upgrades • Chromatic Compensation in Tev lattice • New scope (Cost increase: M&S $150K) • Currently beta-functions for particles with large momentum deviation vary by ~40%. Adversely affects beam-beam effects. Sextupole components will be introduced to correct the chromaticity of beta-function. Important for new working point which will allow more protons. • A review of the project will be held in December.

  13. Scope/Schedule Changes • Tevatron Electron Lens: TEL3 • Reduced Scope (Cost decrease: $340K) • After a review of the status of TEL-2, we have decided to cancel building a third electron lens. TEL-2 tests with new e-gun design and other re-deigned components have been successful. Instead TEL-1 will be modified to be similar to TEL-2. • Cost decrease from canceling TEL3=$600K and costs for upgrading TEL-1~ $260K • IPM • De-scope (No cost implications) • The detector has been built and will likely be installed in the Tevatron next week. The remaining software and commissioning will be handed over to the Tevatron Department.

  14. Reviews • Review Chromatic compensation in the Tevatron • December ‘05 • Review mods to DB Extraction kicker magnet and DB band-4 cooling tanks in Feb. ’06  decision for FY06 shutdown • February ‘06 • Review any newly identified aperture restrictions and make scope decisions • July ’06 • Review Status of Stacktail Bandwidth Upgrade Project • Stack rate • Results from prototype tests if available • July ’06 • Decision point for Bandwidth upgrade in ’07

  15. Change Requests (M&S)

  16. Contingency • V4 Total Estimate:$18098K +$665K = $18763K • Est. to Complete : $18763K - $14469K = $4294K • Available Contingency= total FY04-FY07 budget guidance – Total v4 estimate = $20946K - $18763K = $2283K (53% on estimate to complete) • Contingency held with the Directorate: $2741K before the current CRs
