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


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


FY07 AS Priorities & Goals1. Lumi-Monitors: construct, install, start commissioning2. Tune&Coupling FB: deliver design, participate in

installation and commissioning3. Schottky: participate in installation and commissioning 4. Hardware Commissioning: execute the plan (5-7 people)5. Beam Commissioning: develop detailed Long Term

Visitors TV plan for FY08+ by ~mid-FY076. Other tasks: execute Task Sheet’s Plans7. “5+1”: develop FY08 plan (incl. new tasks) by ~June’07

Hard Deliverable


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


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


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


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

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


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)


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


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
