Proposal for Production Testing of MC Items and Geometry Enhancements (2004-2005)

This proposal outlines the objectives and tasks for the production testing of MC items and related geometry enhancements for the 2004-2005 period. Key features include testing platform set-up, simulation adjustments for new IR and geometry components, and comprehensive evaluations of energy response and clustering efficiency. Each task is accompanied by its current status and identified needs for further studies aimed at refining the simulations. A stringent timeline has been established to ensure that all necessary work is completed by the September 1, 2005 deadline, with a focus on realism and adherence to testing protocols.

  1. MC ’04-’05 objectives

  2. MC ’04-’05 production test proposal • Get the ball rolling! • Platform for testing items nominally done or near completion • Additional items to inserted in a second production test • Features: • 100 pb–1 of 2004-2005 all_phys card at LSF = 0.2 • Standard scripts and offline machinery • Results written to tape library • MCDST's produced. • Delete files after study to make way for 2nd test or real production • Timescale: 01-Sep-05 • Built-in realism regarding August: treat this as firm deadline

  3. Items for production test: Summary

  4. MC work 1/9: Geometry and IR • Simulation of new IR • Geometry added to MC, new card IRTY added (CB) • Status: Ready for production test • New card to specify beam-crossing angle • Add BCAN card (TS) to GEANFI • Official production: Angle calculated from HepDB values • Private production: No way to specify (fixed at 0.0125 rad) • Status: Not necessary for production test • Good idea to add ASAP for individual users

  5. MC work 2/9: EmC energy response • Attenuation lengths in endcap modules • Short/central modules have different attenuation lengths; these were reversed in MC • Status: Simulation fixed (CB), ready for production test • Calorimeter energy scale calibration: • Disable extra y-dependent attenuation factor for endcaps in CLUADJUST module • Need further studies: y-dependence of endcap response, overall energy scale • Status: Futher work requires following items: • Fix attenutation lengths, extra factor in CLUADJUST • SQZ fixed so MCEL cluster energies can be re-read • Can results of a production test be used for further tuning?

  6. MC work 3/9: EmC clusters • EmC time resolution • Common smearing in simulation (140 ps) zeroed (CB, done) • Add common smearing at T0_SMEAR level (MM) • Add cluster smearing in EMCSIMUADJ or other module (MM) • Status: Above items need to be completed. • Testing requires a few pb–1f  p+p-p0 (CG) • Can be done with output from production test? • Cluster efficiency • New parameters for cluster efficiency curves to be put into EMCSIMUADJ and tested (MP, TS) • Status: Parameters exist, need to be inserted • Would be nice to have for production test

  7. MC work 4/9: Generators • f  p+p-p0 generator • FN has a new generator that uses the matrix-element approach. • GEANFI interface not yet done, critical for testing. • Need to add sQED FSR amplitudes. • Status: Needs work, probably not needed for first production test • Secondary generators • KS p+p-e+e- generator (CG) added (CB) with BR = 4.7 × 10–5 • p0 e+e- decay generator added with BR = 6 × 10–6 (CB) • pen decay generator added with BR = 1.23 × 10–4 (CB) • Status: Above items can be looked at in production test • Probably require dedicated testing as well • KS p0e+e- generator (FB, VP) still needs to be interfaced

  8. MC work 5/9: Nuclear interactions • GEANFI nuclear interactions/regeneration code • Original CASK0 code restored as CASK0C, except that regeneration is disabled (CB) • CASK0B is called for interactions in calorimeter • CASK0C is called elsewhere (e.g., DC walls and beam pipe, where regeneration is handled separately) • Status: Testing requires several 10's of pb–1 • Can probably be handled in production test • Do we plan any work for charged kaons?

  9. MC work 6/9: Trigger • Comprehensive data-quality control for trigger • Done up to run 36904 (MP, BS) • Bad runs flagged and/or reconstructed files deleted (MM, BS) • Other work on trigger • Simulation of time smearing in high-jitter/bad RF period • Adjustment of DC threshold simulation • DISH maps • Status: Nice to incorporate any/all of above in production test.

  10. MC work 7/9: DC response • DC tracking resolution: s-t relations • Various volunteers: AA, PDS, MM, TS • Status: No work on solution underway yet • DC tracking resolution: multiple scattering off DC wires • SK interested in working on this problem • Status: Studies beginning, will not condition production test • Correlated noise in DC for charged kaons • Volunteers: EDL, PDS + charged kaon group • Status: No work on solution underway yet • Simulation of dE/dx response • Status: VP has A_C module ready, can incorporate in test?

  11. MC work 8/9: Background • LSB insertion code • Code exists, tested standalone (MM) • Work on scripting to be done (MM) • Status: Necessary for production test • Fixes to CELE structure • Need to add a new field to CELE structure with original CELE index into bank. • Need to modify FILLCSPSMC_CEKA to use this index (MM) Status: Necessary for production test

  12. MC work 9/9: Technical issues • SQZ library • Packing parameters different in GEANFI and KBK modules • Certain MC truth values wrongly scaled or offset on re-reading • MCEL energies (scale ×5) • Particle TOF (e.g., K+) (offset +100 ns) • Unclear why a problem (packing parameters stored in I-banks) • Workaround module FIXIS exists (MM) • Status: Necessary for production test

  13. Items for production test: Reprise
