Realistic Optics and Beam Dynamics Simulation

 Study of the possible locations space, better optics
conditions
 Tracking studies the model should be completed
adding all possible machine imperfections
 Modelisation of the OTR measurements
 Comparison with the multi-wire scanner measurements
            Controls and Software Analysis
 Control needs
    Low-levels drivers for:
      CCD frame grabber,
       V/H movers,
       lens focus movers,
      OTR insertion actuator
    EPICS drivers and Data Base choose hardware controls
   with EPCIS module support
    High-level interface EDM, Flight Simulator…
    Hardware protection for:
       Target damage
       CCD radiation sensitive
              Controls and Software Analysis
 Software analysis
    Can be done in any scripting/programming environment
   supported by EPICS CA (C, C++, Perl, Python, Matlab, TCL…)
       Output processed data to EPICS Process Variables when done
       Scripts/code should also be controlled via PVs
    2D Gaussian filter, taking CCD image and generating
   beam matrix data
       Online Twiss/Emit calculations
       Upgrade FS EXT emittance minimisation application
    Beam finder and tracker
       Track interpolated beam position in OTR target locations using
      adjacent BPMs for faster OTR insertion
       Intermittent target insertions to check tracking
      Piggyback on the software planned for multi-wire system
        Conclusions

The tasks has been identified

We are working on the schedule of the different phases:
Design and Hardware fabrication (~4 months)
 Realistic Optics and Beam Dynamics simulations
  (~2 months)
 Controls and Software analysis (~4 months)

We could give a realistic schedule mid-September 2009
