Summary of Actions¶

• ACTION: Look into TRefArray limits (A. Dobbs)
• ACTION: Fix tracker unpacking and digitisation (E. Overton, P. Kyberd)
• ACTION: Flag low pt for downstream tracker reconstruction (A. Dobbs) Done in personal dev branch, needs testing before merge
• ACTION: Optimize momentum residuals for final tracks (C. Hunt)
• ACTION: Get detector output in global coordinate system (C. Heidt, C. Hunt)
• ACTION: Need uncertainties from detector reconstructions: on positions, momenta, tof time (A. Dobbs)
• ACTION: Restructure TOF Digitisation and incorporate MapCppTrigger (D. Rajaram)
• ACTION: Upload script feature (R. Bayes) Done, in 0.9.5
• ACTION: Pursue uncertainties from TOF and global coordinate transform (A. Dobbs)

Agenda¶

Release status¶

• Current release = 0.9.5
• Targets for release 0.9.6:
  • execute_against_data.py should be always make a tarball
• Targets for future release:
  • Trigger MC
  • Tracker -- pat rec and kalman updates
  • Tracker unpacking and digitisation fix
  • Faster API

Schedule¶

• 2015-05-13_MAUS-Schedule.ods -> 2015-05-13_MAUS-Schedule_updated.ods

Detectors¶

• Detector integration (D. Rajaram)
  • Reconstruction quality flags (A. Dobbs to make requests to detector groups) #1585
• Tracker (P. Kyberd)
  • Space-point, track-finding efficiency studies partly blocked by lack of trigger #1182
  • ACTION: Tracker unpacking and digitisation fix (E. Overton, A. Dobbs)
  • ACTION: Flag low pt for downstream tracker reconstruction (A. Dobbs) Done in personal dev branch, needs testing before merge
  • ACTION: Optimize momentum residuals for final tracks (C. Hunt)
• TOF (D. Rajaram)
  • Restructure TOF MC Digitizer - part of trigger MC (D. Rajaram)
• EMR (F. Drielsma)
  • MC #1033
    • ACTION: Refactor code to remove extra recon events (F. Drielsma) Done, in trunk
• KL (M. Bogomilov)
  • STANDING: MC validation, optimization, tuning, #1411
• CKOV (Drews, Winter, D. Rajaram)
• 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) Update - emailed detector owners, CKOV replied, EMR now implemented and in trunk, no other responses
    • Will also need data structure modifications once we understand how to get the uncertainties

Unpacking¶

• Need to roll out SL6 to Jenkins nodes (P. Franchini)
  • Configure to run with either Step I or Step IV unpacker depending on environment flag, see #1633. Done
  • Need to configure a Jenkins build to regularly check Step I data once we move to the Step IV unpacker as default
• ACTION Fix tracker unpacking and digitisation (E. Overton, P. Kyberd)
• DAQ channel maps to DB (D. Rajaram) #1375, blocked by #994

Infrastructure¶

• Geometry/MC (S. Ricciardi, R. Bayes)
  • Speed improvements (R. Bayes)
• Monte Carlo
  • ACTION: Upload script feature (R. Bayes)
• GRID and Batch Production (C. Rogers, J. Martyniak)
  • Try grid running again? #1489
    • Running 0.9.5
  • execute_against_data.py
• Code deployment
• Documentation
• Data Structure

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
  • No more passing JSON between modules, as string conversions are expensive, only use JSON for configuration data and input / output (A. Dobbs, D. Rajaram, C. Rogers)
    • Extensive refactor work
  • 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

Documentation¶

• Create workbook (A. Dobbs) MausWorkBook.pdf

AOB¶

• MAUS paper draft - developers please review and supply input where required launchpad

Detectors¶

• Detector Integration
• KL
• Ckov
• EMR
• Tracker
  • Tracker unpacking still a block. Some problems identified. No sensible estimate.
  • Integration with CDB progressing well - not on the critical path
  • Alignment studies progressing - may not be ready for first collection of straight tracks
  • Kalman offset corrected - validation of Multiple Scattering and Energy Loss continues
  • C. Rogers points out time is very short to data

• TOF

Global Reconstruction¶

• Tracking and PID continuing to make progress
• Should have PID ready for data taking next month
