  1. Meson Productions at 8 GeV for IDS120h (Update) X. Ding, UCLA AAG Meeting, Jan. 26, 2012

  2. Configuration of IDS120h

  3. Field Map of IDS120h(Bz at r = 0)

  4. The mercury jet target geometry. The proton beam and mercury jet cross at z=-37.5 cm. Meson Production Study IDS120h (Geometry and fieldmap) for HG/GA target Beam below the HG/GA jet exactly at z=-37.5 cm and project beam back to z=-200cm. Initial target parameters: target radius of 5 mm, beam angle of 67 mrad at z=-37.5 cm, beam/jet crossing angle of 33 mrad at z=-37.5 cm. Optimized methods at each cycle (3 runs): 1)  Vary jet radius; 2)  Vary beam/jet crossing angle while keeping jet fixed - always project beam back to z=-200 cm; 3)  Vary jet angle-always keep crossing angle constant-both jet and beam must be rotated about intersection point together and always project beam back to z=-200 cm.

  5. Optimized Target Parameters at z = -37.5 cm

  6. Meson Productions at 8 GeV(400,000 events)

  7. Meson Productions Vs. Run No.(Number of runs: 0-Initial, 1,4,7,10,13,16-optimized target radius, 2,5,8,11,14,17- optimized crossing angle, 3,6,9,12,15,18-optimized beam angle )

  8. Focused Incident Proton Beam

  9. Focused Incident Proton Beam (Cont’d) Non-Linear Fit (Growth/sigmoidal, Hill) Y=N/(1+K2/beta-2) N=1.018 Sqrt(K2)=0.1368 Linear emittance is 4.8 μm with beam radius of 0.12 cm and β* of 0.3 m.
