  1. Updates on Tevatron and LARP Vladimir Shiltsev FNAL/Accelerator Physics LARP/Accelerator Systems

  2. In short Yesterday, CDF Detector celebrated 2fb-1 of data delivered !  FY07 goals ~1750 / 760 pb-1 Delivered by Nov.1 50 pb-1 FY06 goals 725 / 580 pb-1 Delivered 620 pb-1 APEX Mtg 11/02/2006 - Shiltsev

  3. Pbar production task force initiated Dec-Feb 2006 Best luminosity before shutdown: 171e30 cm-2s-1 25 pb-1/week Shutdown to Upgrade D0 detector Mar-June 2006 Fast start up (<2 weeks) Rush of records: 171182191205228229e30 Current best: store 229.0e30 (avg CDF & D0) week 33pb-1 month ~120pb-1 Average store 27-32 hrs (longest 54hrs), ~120-130 hrs/week 36x36 bunches ~270e9 p/bunch, 60-80(max) pbars/bunch Details APEX Mtg 11/02/2006 - Shiltsev

  4. Reduction of beta* to 28 cm Sep’05 ~8 % Pbar production task force Feb’06 ~10 % Tevatron 150 GeV helix more p June’06 ~10 % Tev collision helix  lifetime July’06 ~15 % New RR WP  emittances, loss Sep’06 ~25 % D0 luminosity counters rescaled Oct’06 15/2=8% Improvements over last ~1yr APEX Mtg 11/02/2006 - Shiltsev

  5. Content APEX Mtg 11/02/2006 - Shiltsev

  6. Pbar production (not cooling!) : still less 20e10/hr Beam-beam effects in Tevatron: Ksi~0.025 for pbars  losses/emittances Ksi ~0.015 for protons  losses/emittances Availablity: component failures no L time 10/30/06 - ??11/08/06?? Tev Cryo vacuum 10/09/06 - 10/23/06 Tevatron Q,D,spool 02/23/06 - Tev magnet failure , early Shtdn start 01/14/06 - 01/27/06 Tev magnet 01/03/06 - 01/06/06 AA magnet 11/22/05 - 12/12/05 Tevatron magnet Plus, power glitches, etc: Jul-Aug’06: 45 stores , 15 aborts/quenches Sep-Oct’06: 36 stores , 17 aborts/quenches Major Limitations APEX Mtg 11/02/2006 - Shiltsev

  8. Pbar production: AA optics Faster AA to MI to RR transfers (<15 min) Pbar Target optimization New Tevatron WP: To improve luminosity lifetime (less losses, no dEmm) Allow higher Np and Na Next Steps (till ’09?) (yr?) V.Lebedev APEX Mtg 11/02/2006 - Shiltsev

  10. STATE of LARP …after • Doe Review Jun’06 • LHC Upgrades Workshop in Spain, Oct’06 • LARP Collaboration Meeting at BNL, Oct’06 • Executive Committee Mtg, Oct’06 APEX Mtg 11/02/2006 - Shiltsev

  11. LARP Accel Systems Progress ‘06 • Schottky being baked, will go into LHC tunnel • TCFB: success at SPS • 4 long-term hardware commissioners @CERN • SLAC joins commissioning forces • LHC@FNAL to open in Nov’07, new - LAFS • RC work at full speed, a lot of changes, delay • SPS beam studies: BBQ PLL, Q’ head-tail, bent crystal, etc • Wires built for RHIC tests • # of LARP presentations at Valencia workshop APEX Mtg 11/02/2006 - Shiltsev

  12. 4.8GHz Schottky Detector APEX Mtg 11/02/2006 - Shiltsev

  13. PLL Success on SPS Ramp APEX Mtg 11/02/2006 - Shiltsev

  14. 2007 – First Year of “Deliverables” • “Hard deliverables” are the projects which CERN needs but can not back-up itself in case of failure (thus, special attention and protection needed): • Lumi Monitors for 2 IPs (2007) • Tune Feedback (2007) • Beam Commissioning (2007-2009-beyond) • Phase II rotating collimators prototype (2009) APEX Mtg 11/02/2006 - Shiltsev

  15. Accelerator Systems FY07 Priorities • Lumi-Monitors: construct, install, start commissioning • Tune&Coupling FB: deliver design, participate in installation and commissioning • Schottky: participate in installation and commissioning • Hardware Commissioning: execute current plan – SAFELY! • Beam Commissioning: develop acceptable/detailed execution plan for FY08+ by ~mid-07 (more from BNL!) • Physics experiments: RHIC (BBLR), Tevatron(PLL), ecloud • Other tasks: execute Task Sheet’s Plans APEX Mtg 11/02/2006 - Shiltsev

  16. CARE–HHH: upgrades discussed • IR Upgrade: • both quad first paths NbSn, NbTi • Magnet R&D… Magnet R&D…MagnetR&D • D0 3.5m from IP • <1mrad Crab Crossing not excluded • Low cost, potential high gain: • low-noise feedback • collimator schemes (RC, LEL, Crystals) • beam-beam compensation schemes (W,LEL) • Upgrade of Injector Chain: • new Linac, PS+, PS2 • SPS+ incl. SF-SPS APEX Mtg 11/02/2006 - Shiltsev

  17. wires (2.5m long) with strong-back (-profile)7 support points NEG coated chambersduring assembly RHIC BBLR wires – assembly APEX Mtg 11/02/2006 - Shiltsev

  18. Things not in FY’07 budget Project Reason • Longitudinal Density Monitor budget • Fast Magnet Ramp Measurement System budget • Crab Cavity – hardware part budget • E-lenses budget • Bent Crystal collimation (see below) too early • LER-LHC 1.5TeV (see below) little $$ • Optical Stochastic Cooling too big for LARP APEX Mtg 11/02/2006 - Shiltsev

  19. Summary: • DoE Review was (overall) successful • LTVAC started • Instrumentation tasks are of the highest priority in FY’07 • Constrained by budget, #of tasks dropped • Plans to further improve CERN-LARP communication APEX Mtg 11/02/2006 - Shiltsev
