  12. LARP AS : Focus on Junior Physicists • They are active in all tasks: • Rama Calaga (Toohig Fellow), Mei Bai (Commiss.), Guillaume Robert-Demolaize (Collim. , 1/2 by RHIC), Natalia Prado de Abreu (Physics, 1/2 by RHIC), Yun Luo (Commiss) – at BNL • Ryoichi Miyamoto (AC dipole), Andreas Jansson (Schottky), H.J.Kim (IR), Arden Warner (Commiss) - at Fermilab • Jean-Francois Beche (Lumi) – at Berkeley • We are actively looking for new ones: • Toohig Fellows • 1 Research Associate for Lumi (Wainer Vandelli, Piza) • 1 RA for Rotating Collimator (Javier Resta Lopez) • 2 from SLAC to take part in commissioning LARP Collaboration Meeting

  13. Collaboration/Coordination with CERN • Remarkable progress in 2006: • closer contacts established • “driving forces on both sides” model: • Luminosity monitors: A.RATTI and R.JONES • Schottky detectors: R.PASQUINELLI and F.CASPERS • Tune & Coupling FB: P.CAMERON and R.JONES • AC Dipole: S.KOPP and H.SCHMICKLER • HW Commissioning: M.LAMM and R.BAILEY • Beam Commissioning: M.SYPHERS and M.LAMONT • Collimation: T.MARKIEWICZ & R.ASSMANN LARP Collaboration Meeting

  14. Collaboration with CERN in FY07 • Better coordination of all activities in FY07: • H.Schmickler/AB in LARP LTV Advisory Committee • O.Bruning/AB to be liaison to LARP IR,e-cloud work • J.P.Koutchouk/AT to be liaison to LARP beam-beam compensation projects (long-range & head-on lenses) • More collaborative work: • Even more visible LARP presence at CERN for • Installation and commissioning of LARP instruments • Participation in the next round of SPS studies • 2 more Hardware/IR Commissioners to come • First LARP Beam Commissioners - later in 2007 • Joint eCloud Clearing workshop @CERN (Mar’07) • Joint LHC beam-beam&IR workshop at SLAC, Jun’07 • Org’d by A.Chao & W.Fischer; to review experiments& simulations LARP Collaboration Meeting

  15. FY07 AS Priorities & Goals • 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 the plan (5-7 people) • Beam Commissioning: develop detailed Long Term Visitors TV plan for FY08+ by ~mid-FY07 • Other tasks: execute Task Sheet’s Plans • “5+1”: develop FY08 plan (incl. new tasks) by ~June’07 Hard Deliverable Hard Deliverable Hard Deliverable LARP Collaboration Meeting

  16. This Meeting • This is “large” meeting to address: • Plan execution, achieved milestones, finances • Expected schedule/cost changes in FY07 • Plans for FY08 and beyond • It is the meeting to report/discuss • Technical achievements, in detail • Difficulties of any kind • Status of collaboration affairs (US labs, CERN) • Very important • Open discussion of new proposals (Thur PM) • Welcome new people joining us • from SLAC • from various Fermilab groups LARP Collaboration Meeting

  17. New Initiatives • Collider Instrumentation • BBQ-based Quadrupole Monitor • Synch light based diagnostics • Physics • LHC Crystal Collimation Scheme • LHC Electron Lenses • Modeling of LLRF Limitations on LHC Performance • LHC Injectors • The Low-Energy Transverse Emittance Project • Super-Ferric Fast Cycling Injector in the SPS Tunnel • LHC injectors Upgrades, space-charge effects LARP Collaboration Meeting

  18. Consideration Process • “Group of 5+1” to meet right after to recommend on support of proposals • General requirements: • Interesting subject, development should push up the state of the accelerator physics and technology in the US • Of interest for LHC • Collaboration of >1 Lab, Universities welcome • Not at expense of current unfinished tasks • Right time and budget scale • Final approval by LARP Executive Committee LARP Collaboration Meeting

  19. Summary: • Remarkable progress since last LARP meeting: • Instrumentation tasks, Hardware commissioning • Rotating collimator design, Beam-beam wires, etc • Greatly improved LARP-CERN communication • Priorities in FY’07: • instrumentation tasks, • commissioning • LTV Advisory Committee started: • focus on junior researchers LARP Collaboration Meeting

  20. Back up slides LARP Collaboration Meeting

  21. AP: New Proposals vs Existing Tasks • Electron cloud (200k$/yr): • very high priority for the LHC, a lot of interest from US projects, now attacking e-p interaction simulations (new territory) • IR Optics and Beam-Beam Simulations (270k$/yr): • Making important contribution to LHC Upgrade work (12 talks in Valencia), plugs US into the LHC Upgrade consideration process as a pratner, develops software tools of particular importance for the LHC and generic importance for US colliders (beam-beam lifetime) • Beam-beam wires (150k$/yr): • Very positive development at CERN (there will be wires, space reserved), effective CERN-LARP collaboration, experiment at RHIC greatly enhances advanced accelerator R&D in the US, little funds after FY’07 LARP Collaboration Meeting

  22. Instrumentation Tasks in FY’07 and FY’08 • Schottky & Luminosity Monitors, Tune Feedback : • Are or will be constructed and installed in FY07 • LARP will support their commissioning (via Commissioning task) in FY’07 and – in larger scale - in FY’08 (including 450 GeV run) • AC Dipole: • Just started, significant design progress expected in FY07  will determine funds needed in FY08 • Being discussed: • Longitudinal Density Monitors, Crab Cavities, ODR monitors • Funds in FY08 will depend on situation with higher priority tasks, e.g., commissioning of existing instruments (TBD after collaboration meeting in April’07) LARP Collaboration Meeting

  23. New Physics Initiatives • Crystal Collimator (~50k$ 1st year): • waiting for Tevatron results with new bent crystal, not much encouragement from CERN, competes with Rotating Collimator for Phase II • Superferric LER or (S)PS (~100k$ 1st yr): • LER is “dead”, Super Ferric (S)PS+ m.b. considered later – depends on CERN plans, no strong inter-Lab team in the US • Hollow electron beam as proton/ion primary collimator (~50-100k$ 1st year): • Some interest at CERN, initial considerations to take place in FY07  technical considerations possible • Electron lens for beam-beam compensation (300 k$ 1st yr, ~600+ k$/yr x 4 yrs): • Preparatory theory work not done, some limited interest at CERN, working collaboration may be formed in FY07 • encouraging TEL results (doubles p-lifetime) • NB: before funding other things, we need complete current commitments (Instruments) as the highest priority LARP Collaboration Meeting

  24. LHC Software at Fermilab (LAFS) • Motivation: make vast Tevatron accelerator controls experience available to the LHC operation team • Goal: to develop a suite of software products to enable Fermilab accelerator physicists to make key contributions to the beam commissioning of the LHC • A modest team (~3-5 FTE’s or 10 people) of computer professionals, operational experts, and accelerator physicists to make a substantial contribution to the LHC • LAFS is part of LHC@FNAL • Head – D.McGinnis – reports to E.Gottschalk • Three groups: • RBA (Role Based Access) – S.Gysin • Sequencer – J.Patrick • SDA – Sequenced Data Acquisition – E.McCrory • Collaborative agreement FNAL/CERN is signed by S.Holmes (last week)  now at CERN • Relationship to LARP : • Complementary: • LARP input via LHC@FNAL Integration Task Force LHC subgroup LARP Collaboration Meeting
