  1. Proton Position Tracking X. Ding, D. Cline UCLA H. Kirk, J. S. Berg, BNL Phone Meeting on Aug. 25, 2009

  2. Multiple Proton Beam Entry DirectionsThe Required Beam Position at z=-75cm to Keep Same Crossing Angle and 240 Roll Angle Apart at z=-37.5cm Hg Jet: (0, 3.64, -75) rj=0.4 j=96.68 mrad P0: (-0.56, 4.62, -75) b=123.73 mrad P7: (-0.103, 2.638, -75) b=70.45 mrad All entry directions of Hg jet and proton beam which have small angles to solenoid axis are down at z=-75cm

  3. Multiple Proton Beam Entry DirectionsMeson 40MeV<KE<180 MeV at 50m for Same Crossing Angle and 240 Roll Angle apart at z=-37.5cm p11 p6 p4

  4. Beginning position where the beam hits a vertical plane

  5. X-Z plot of launched protons which meet horizontal plane at y=-14cm

  6. X-Z plot of launched protons which meet horizontal plane at y=-20cm
