26 Oct 2010PC Physics Requirements of Software from Chris R ~19 Oct. My (reactive) comments/thoughts in red Monte Carlo (Simulation) * Model all MICE fields from target o Do we want to be able to model arbitrary 3d mesh for field map measurements? Prefer not to – but probably need to... Cooling Chan gets priority * Model all MICE geometry from target – really need to start so far upstream? o Provisional - plan CAD parser to take engineering model into G4MICE Suspect this would be difficult; needs the right CAD models & maybe help of designers / engineers ??? (& who pays for their time?) Do we really need all the detail that would give? o needs heavy intervention to add fields, make sure diffuser/proton absorber/etc is right (how much matters?) o Provisional * Model all detectors – in (no more than) sufficient detail * Custom dE/dx and Multiple Coulomb Scattering routines At least the ability / option to use these * Model spill structure (why?) and input beam distributions * Physics verification - automated and publicly available for each release (KS tests?) What are KS tests? Kolmogorov-Smirnov ??? *** Do we need formal Change Requests, e.g. if some model / implementation changes ??? o Need help/feedback from analysis group to let me know what is sufficient here

26 Oct 2010PC * RF background model How good a model do we have? Beam envelope pusher What about Turtle / Transport... for beamline? * Calculation of transfer matrix o For arbitrary electromagnetic field maps * Transport of particle trajectories * Transport of beam envelopes * Transport through material (with some simple model) * Optimiser Online analysis tools * Calculation of emittances, Twiss parameters * History plots o Twiss parameters vs run number, etc Date & time as/more useful as run number Anything that is calculated per run/hour/day – e.g. electron-tof peak versus time * Beam plots o phase space plots, amplitude plots, etc * Scriptable interface ??? * Tools to calculate mappings * Tools to do statistical weighting o Fancy image manipulation tools * Offline use

26 Oct 2010PC Reconstruction * Track position, momentum, time, track fit quality Errors, Error matrix RF phasing / time in first cavity (or something) o At arbitrary z-position (but mostly interested in inner plane of trackers) o With arbitrary collection of detectors (quite analysis-dependent) ???? With all operating detectors (i.e. those that exist & switched on!) * EM shower reconstruction for KL/EMR Muon range / energy from KL/EMR Particle ID PID from TOFs & Ckovs * Muon momenta / 4-vector from TOFs EventDisplay * Display hits + detector elements hit What’s the difference? * Display reconstructed and monte carlo (? Simulated ?) trajectories * Display beam envelopes Calibrations / Stabilities / Alignment / Survey measurements - Procedures for these Database / Epics interfaces and access RF diagnostics
