Revision 20 (Rogers, Chris, 26 June 2018 11:43) → Revision 21/22 (Rogers, Chris, 26 June 2018 11:44)
h1. 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: attachment:RALSitePlan.pdf h2. System performance paper: Monday morning [[System-performance-paper_2018-06-25|System performance paper meeting page]] h2. Scattering - referees: Monday afternoon h2. Long Emittance Paper: Tuesday Morning Morning? h3. Monday Long emittance paper Discussion Objectives * 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 h3. Tuesday 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
