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

17

18
Consideration Process

• Group of 51 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 gt1 Lab, Universities welcome
• Not at expense of current unfinished tasks
• Right time and budget scale
• Final approval by LARP Executive Committee

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 RD in the US,
  little funds after FY07

22
Instrumentation Tasks in FY07 and FY08

• Schottky Luminosity Monitors, Tune Feedback
• Are or will be constructed and installed in FY07
• LARP will support their commissioning (via
  Commissioning task) in FY07 and in larger
  scale - in FY08 (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 April07)

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

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 FTEs or 10 people) of
  computer professionals, operational experts, and
  accelerator physicists to make a substantial
  contribution to the LHC
• LAFS is part of LHC_at_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_at_FNAL Integration Task Force
