  1. Beam-Beam-Backgroundwith Vertical Offsets André Sailer LCD Group Meeting February 9, 2010

  2. Vertical Beam Offset • GuineaPig • Vertical Offset • Beginning: 0.02 nm steps • Later : 0.2 nm steps • Used 66 Runs/ Step • Vertical Grid size = 0.007 nm (±30nm) • Animation with Offset • Number of Incoherent Pairs decreases • Number of Coherent Pairs increases André Sailer - LCD Group Meeting

  3. Angular Distribution (Macro Particles) Opposite Charge as oncoming Beam Same Charge as oncoming Beam André Sailer - LCD Group Meeting

  4. Angular Distribution (Relative Difference) Opposite Charge as Oncoming Beam Same Charge as oncoming Beam André Sailer - LCD Group Meeting

  5. Need more Statistics • Right side: 1000 runs without vertical offset • 1-2 h/run, • Batch Farm was acting up last week • Both same/opposite charged particles shown • Coherent1/2 is for the two beams André Sailer - LCD Group Meeting

  6. Outlook • Angular Distribution of incoherent Pairs • When does the number of coherent Pairs subside • Produce large Statistics for a few points • Expected vertical offsets of beams? André Sailer - LCD Group Meeting
