  1. Bucket Area for h = 1,2,3Vrf = 60kV, Frep=10Hz, Sinusoidal Ramp, 75% Rise time( Complement to my presentation of 30/03/2011) Abucket eVs Vrf (kV) Min. Values [eVs] Abucket / Abucket/4 h=1 …3.0 / 0.75 h=2 …1.1 / 0.27 h=3 …0.57 / 0.145 PSB Energy Upgrade Working Group 14/04/2011

  2. Steve Hancock’s LHC Beam Parameter List PSB Energy Upgrade Working Group 14/04/2011

  3. Proposed RCS Parameters • Circumference C = 4/21 CPS • h = 1 + 2 -> hPS= 7 (implies bunch splitting to h = 21 in the PS) • Alternatively (If RF system allows): h = 4 16 bunches into hPS= 21 buckets; • fast bunch blow-up at the end of the RCS cycle PSB Energy Upgrade Working Group 14/04/2011

  4. Example Lattice (18 Cell Racetrack)(M. Fitterer) C=119.68 m, Q1 = 5.14286, Q2 = 5.14286, gammat=4.92 PSB Energy Upgrade Working Group 14/04/2011
