Agenda¶

Release status¶

• Current release = 1.0.0
• Targets for release 1.1:
  • execute_against_data.py should be always make a tarball
  • Support for gcc 4.9
  • Updates to Geometry handling
  • EMR reducer
  • SciFi CDB interface
  • SciFi mapping and calibration update
• Future release
  • Updated tracker noise

• Workbook added

• Targets for future release:
  • Trigger MC
  • Fix memory leaks
  • Tracker -- Kalman updates

Schedule¶

• 2015-09-16_MAUS-Schedule.ods

Detectors¶

• Detector integration (D. Rajaram)
  • Reconstruction quality flags (A. Dobbs to make requests to detector groups) #1585

• Tracker (P. Kyberd)
  • Tracker plane ordering bug Fixed in trunk, mapping error corrected
  • Observe that tracks when visualised do not appear to line up between trackers, in both position and slope
  • Space-point, track-finding efficiency studies partly blocked by lack of trigger #1182
  • ACTION: Optimize residuals for final tracks (C. Hunt)
  • ACTION: Fix close to paraxial tracks producing nan output (C. Hunt)
  • ACTION: Update tracker online plots (P. Kyberd)
  • ACTION: Update tracker schedule (P. Kyberd)
  • ACTION: Update ConfigurationDefaults with tracker optimum parameters
  • ACTION: Set HelicalPR on or off depending on CDB value of magnetic field (C. Hunt)
  • Flag low pt for downstream tracker reconstruction? (A. Dobbs)
• TOF (D. Rajaram)
  • Restructure TOF MC Digitizer - part of trigger MC (D. Rajaram)
• EMR (F. Drielsma)
  • MC #1033
• KL (M. Bogomilov)
  • STANDING: MC validation, optimization, tuning, #1411
• CKOV (A. Liu, Drews, Winter, D. Rajaram)
  • MC Digitizer update attachment:MAUS_Ckov.pptx.pdf
• Monte Carlo trigger (D. Rajaram) #1182
  • ACTION: Restructure TOF Digitisation and incorporate MapCppTrigger (D. Rajaram)

Global Reconstruction¶

• Tracking (J. Greis)
• PID (C. Pidcott)
• Detector output
  • ACTION: Get detector output in global coordinate system (C. Heidt, C. Hunt)
    • See #1631
  • ACTION: Need uncertainties from detector reconstructions: on positions, momenta, tof time (A. Dobbs)
• ACTION: Implement dE/dx in Runge-Kutta (M. Uchida)
• Need uncertainties from detector reconstructions: on positions, momenta, tof time (A. Dobbs)

Unpacking¶

• Need to roll out SL6 to Jenkins nodes (P. Franchini)
• DAQ channel maps to DB (D. Rajaram) #1375, blocked by #994

Batch Reconstruction¶

• GRID running 1.0.0
  • Enable MC GRID running again #1739
  • execute_against_data.py to always produce tarball
• Fix memory leaks

Infrastructure¶

• Geometry/MC (S. Ricciardi, R. Bayes)
  • ACTION: Make current beamline geometry available in CDB (R. Bayes)
• Need C++ Reducer example (A. Dobbs)
• Documentation

Online¶

• Online reconstruction (A. Dobbs)
• Have prototype GUI and prototype ROOT-based document DB to replace maus-web-app and django #1312 (C. Rogers)
• Software On Call (A. Dobbs)
  • http://micewww.pp.rl.ac.uk/projects/maus/wiki/Software_on-call (SOC wiki)

Performance¶

• Speed improvements
  • Fix memory leaks - preventing GRID runnning (A. Dobbs, D. Rajaram, C. Rogers)
  • YK proposes parallelising MAUS with C++11 multi-threading, at the mapper level, see #1638 (A. Dobbs, D. Rajaram, C. Rogers, Y. Karadzhov)
    • Extensive refactor work

• Beam generation excessive resource usage
  • Query analysis group requirements (in particular how many G4BL beams we need)
  • Consider alternative upstream beam generation code

Tools¶

• Add V. Blackmore event visualiser to MAUS
