Global Reconstruction¶

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

Monte Carlo¶

• Monte Carlo trigger (D. Rajaram) #1182
  • ACTION: Restructure TOF Digitisation and incorporate MapCppTrigger (D. Rajaram)

Geometry¶

Online Reconstruction¶

• 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)

Batch Offline Reconstruction¶

• GRID running 1.0.0
  • Enable MC GRID running again #1739
  • execute_against_data.py to always produce tarball Is this still relevant?
• Offline Rec running 1.3.0

Infrastructure¶

• ACTION Fix geometry test which randomly produces large SOAP error (R. Bayes)
• ACTION Fix problems when setting header_and_footer_mode to "dont_append" (C. Rogers, C. Pidcott)
• ACTION Fix matplotlib install (A. Dobbs)

Performance¶

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

Tools¶

Event Viewer¶

• Add event viewer to MAUS #1799

Documentation¶

• Update tracker (C. Heidt)
• Update geometry (R. Bayes)

AOB¶

Notes¶

Attendance¶

R. Bayes, J. Greis, C. Heidt, J. Nugent, C. Pidcott, D. Rajaram, M.Savic

Release Status¶

Schedule¶

A. Dobbs needs to fix formatting and email those who need to provide updates.

Detectors¶

Data analysable flags for each detector now to be implemented in post-processing, info then shown in CDB. D. Rajaram can implement, but detector groups still need to specify their 'good' or 'bad' criteria.

• KL
• Ckov
• EMR
  Loads of new work to go in to trunk. F. Drielsma will give a presentation soon when code is ready.
• Tracker
  Coordinate flip issues seem to be fixed! Need to do more checking but looking good. Seem to see momentum flips in final track fit for straights however (no corresponding study for helical yet) - referring to C. Hunt.
• TOF

Global Reconstruction¶

J. Greis blocked by tracker flip issue. Should be able to make quick progress when fix is in place. JG also waiting on C. Pidcott test updates, which should be done soon.
When various blocks are out of the way shouldn't been too long, depending on what surprises appear, to being able to do performance analyses on global tracking. Estimate time of somewhere in January.

Monte Carlo¶

DR has profiled code during MC running. Slowness mainly due to GEANT4 stuff. Considerable job to fix. Manpower issues.

Geometry¶

Bug in downloading cooling channel currents from CDB. R. Bayes expecting to fix merged within a week (targeted for next release).

Online Reconstruction¶

Y. Karadzhov now leading effort on new OnlineRecon system

Batch Offline Reconstruction¶

MC GRID running needs a champion. Possibly D. Maletic. M. Savic will talk to him, D. Rajaram and A. Dobbs the contact points.
OfflineRecon machine now running MAUS-v1.3.0.

Infrastructure¶

SOAP error probably arises from hack on the server which restarts PostGres (due to a memory leak). When PostGres is restarting get the SOAP. Could get each MAUS cdb call to also try a different slave if communication fails. NO manpower to implement the fix at present.

Performance¶

See MC notes.

Tools¶

Lots of progress on event viewer development. See issue #1799. M. Savic still seeing problems when trying to get spacepoints to match detector positions and PR fit output (trackpoints now seem ok). Wait until tracker fixes go in, then look again, and use spacepoint get_global_position method. A. Dobbs trying to get straight pr track parameters to output in global coords too.
