Workshop Summary (presented at PSTP '07, BNL, 9/14/07)
Working Group Update (presented at EIC Collaboration Meeting in Stony Brook, 12/8/07)


EIC Lattice Design for Interaction Regions


ELIC

a)

Figure-8 Electron Ring – Small Equilibrium Emittance Lattice
Figure-8 Ion Ring – Minimum Dispersion Lattice

2005 Particle Accelerator Conference Proceedings

Note,

  1. that these are "old" optics design, a major revision are currently underway.
  2. The following changes of optics are expected in the new optics:
  3. the new optics should be available in 3 to 4 weeks time frame

b)

Figure-8 Ring design (ps)
electron_Ring (mad), (TWISS)

Note,

  1. this is the latest optics design (Feb 2008)

eRHIC

ring-ring lattice

Note,

  1. this a "twiss" file that describes the eRHIC ring-ring lattice; however, this version still has innermost IR magnets at 1m from the IP, not 3m. I don't think a version with magnets at 3m exists yet.
  2. If you are unfamilar with the format of these files, here is a quick explanation
