  1. Software discussion What do you want? What are you willing to do to get it? J. Arrington, Argonne National Lab Hall C collaboration mtg, Jan 2010

  2. Data Analysis • Hall C analysis “engine” well suited to SHMS • Identical (fortran-based) code used for HMS and SOS hodoscopes, chambers, calorimeters • Built-in calibration codes for some detectors; options for outputting calibration data • Very easy to incorporate SHMS • Trivial changes for geometry, channel differences • Minor modifications for fly’s eye calorimeter • Small changes for new ADC/TDC modules • Want to develop C++/ROOT based analyzer • More advanced programming language • More direct connection to ROOT data presentation/analysis tools (including Hall A) • Easier inclusion of new detectors, third arms ?

  3. Plan under discussion (default option) • Develop C++/Root analyzer • Use Hall A version • New framework? • Update the fortran “engine” as backup option • Easy to update; most of work is to decode ADC/TDC/scalar info • Ready to go if needed. Realistically, once C++/Root analyzer is working, all engine support disappears

  4. Current efforts, short-term plans • Start work in preparation of analysis updates • Document current codes, algorithms • Lay out work needed to adopt PODD or make new framework • Put SHMS into engine (identify areas needing new code) • Volunteers • G. Niculescu: Document engine, start on new analyzer • M. Jones: Coordinate initial efforts • E. Brash, J. Reinhold, W. Boeglin: make time/students available in the summer • Interested (but not yet useful) parties: S. Wood and myself • Looking for user input, more interested and/or useful parties • Do we have real PODD experts in Hall C?

  5. Questions • Is any of this what we want actually want? • What else do we want/need? • New/different capabilities for analyzer? • Have SIMC/single-arm with SHMS model • Need GEANT4 simulation? [G. Huber looking at 1st efforts] • Small packages for individual detectors? • Global detector hut simulation? • Full spectrometer (hall) model?
