Comments about Project X 8 GeV Proton Physics
program

• Why the muon and kaon people should stop thinking
  about acquiring the Antiproton Source for 8 GeV
  proton physics program during Project X
• Or
• The Antiproton Physics Group should look at a
  long term program
• Keith Gollwitzer
• Antiproton Source
• Fermilab

Project X 8GeV Physics Program

• Recycler to Accumulator
• Large Ring to small ring
• Ratio of circumferences is 7
• Injection scheme of filling aperture
• Accumulator Aperture is 150 of Recycler
• Debuncher Aperture is 600
• Beam current
• 4 Project X linac pulses into Recycler and then
  to Debuncher means 22.5A of current.
• Nightmare to get desired beam structure for kaon
  and muon experiments

Project X 8GeV Physics Program

• Dave McGinnis and I met with representatives from
  both the kaon and muon groups
• 8 GeV proton beam to the Antiproton Source using
  the Project X linac does not appear feasible
• 8 GeV proton beam fed from Booster to Antiproton
  Source is probably on the edge
• Suggested that they explore new rings of the
  size of the Recycler or larger (TeV tunnel?)

Project X Antiproton Physics

• With the current Antiproton Source, stacking 10
  of the time means that effect on 120GeV neutrino
  program is a loss of 10 of 1/6 of the available
  120GeV protons. (nearly the same for pre-Project
  X)
• We should be looking at a long term program
• No end date due to Project X completeion
