MC scenario

  • R. Palmer P5 meeting’08 @ BNL
  • S. Holmes NFMCC meeting’08
  • Y. Alexahin NFMCC meeting’08

Low Emit: Low # muons/bunch & many bunches High Emit: High # muons/bunch & one bunch RLA plays a key role since it makes a limit of the number of bunches and the number of muons

These numbers are based on the assumption the number of muons are same as HE scheme. We need to re-estimate them.
