Sep 23 2016 JLEIC Ion Integration Meeting

Ion linac parameters and extending linac baseline files to high energy (Todd)

• Added the ion linac parameters to the JLEIC baseline parameters page.
• Added TRACK code and supporting lattices to the JLEIC svn repository.
• These parameters are currently only modeled for the low energy (134 MeV p, 44 MeV Pb) option.
  • That lattice was designed and delivered by P. Ostroumov, B. Mustapha, and A. Plastun (ANL).
  • Plot of low energy lead energy vs S
• Consulted earlier this week with Peter Ostroumov about the best way to extend the linac to high energy (280 MeV p, 100 MeV Pb)
• Do not need additional types of HWR cryomodules with different cavities; existing cavities optimized for beta=0.3 will do.
• Have about 7.5 MeV of energy gain per cryomodule for Pb, so need 8 more beta=0.3 cryomodules in linac for high energy.
  • This is despite final high-energy option betas of 0.64 (p) and 0.43 (Pb).
• Expect to have parameter and lattice update for high energy option before collaboration meeting in two weeks.
