Analysis Working Party

Start time is 9 am on Monday 25th June, 10 am on Tuesday 26th. The room will not be locked overnight so feel free to come in earlier (and/or stay later).

We will be in CR13, near the South car park. There is a map here: RALSitePlan.pdf

System performance paper: Monday morning

System performance paper meeting page

Scattering - referees: Monday afternoon

Long Emittance Paper: Tuesday Morning


Long emittance paper

  • Convergence of the MC simulation Model
    • Dipoole model implemented; target model not implemented but doesn't appear to be sensitive
    • Tracker model believe implemented
      • Plan to measure density and geometry by <someone>
      • Plan to look at chi2 of straight tracks
  • Plan for the integration of field models into systematics studies
    • Asked Joe L to upload the field map files; Paul J looking into comparing with MAUS models
  • Performance of track fit and possible future upgrades
    • Discussed issues to do with track fitting and low pt tracks; comments from Francois by email
    • Chris H reviewed tracker tof refit routines and Chris R agreed to have a go at running them
    • Chris H has done some track fitting using non-uniform fitter; it might work
  • Standardize the datasets and some cuts
    • Discussed using all (within reason) data
    • Discussed presentation of results
      • Propose sum all beam line settings for a CC magnet configuration; select subsamples for analysis
      • Selected configurations comparison of emittance change vs input emittance
      • Comparison of equilibrium emittance vs CC magnet configuration
      • Parameterisation of amplitude change to exclude aberrations and emittance growth; comparison vs CC magnet configurations


Target discussion
  • Discussed plans for the target model
Some diffuser discussion
  • Looked at high radius issue for 10 mm beam
  • Discussed modified geometry model as implemented by Durga/Rogers
Some tracker discussion
  • Discussed chi2 issue
  • Discussed MC dead channels issue
  • Chris H promises to deliver plot for system performance paper
Energy loss analysis
  • Working through systematic uncertainties
