*Showed IBSimu beam profiles at z=0 and z=135mm from Ricardo. See: [[:File:Initial Distribution.png | Initial Distribution Plots]] and [[:File:Emittance_Plots.png | Emittance Plots]]. Josh will try to reproduce/compare with GPT simulations

*Simulating electron beam only (no ions for now) using E-Field and B-Field maps with GPT and IBSimu. Will make plots of xrms, yrms, bunch length, emittance, etc. along the beamline. When electron models/plots agree, we can simulate ions.

  • Create a "killmap" (Map3D_Remove GPT function) from stepfile?
  • Solenoid and second steerer field maps are overlapping...perhaps move second corrector upstream to z=0.5m? - need same kicks on both correctors so that the beam returns to center
  • Perhaps use physical values of steering coils (in G-cm)
  • Make plot of Cristhian's B & Φ on axis (including solenoids, correctors, and E-field)
  • Start at 135mm with correct particle distribution (i.e. use screen at z=135mm) for easy comparisons with IBSimu
  • Correct x vs y plot (Python) - update axis labels
  • Pick solenoid lens setting for small beam at dipole
  • Fix 15 deg dipole field map link (wasn't working at time of meeting) and upload to wiki w/comment
