Release status¶

• Current release = 3.0.0

• Targets for release 3.1.0:
  • Cuts data structure object (M. Fedorov)
  • Tracker validation criteria (P. Kyberd)
  • Fix low TOF2 efficiency (S. Wilbur)
  • Fix TOF momentum discrepancy (S. Wilbur)
  • Tracker reconstruction 50 MeV/c (A. Dobbs, C. Hunt)

• Targets for future release:
  • Multithreaded MAUS (A. Dobbs, D. Rajaram)
  • Event Viewer Reducer (M. Savic)
  • Tracker -- purity analysis code (A. Dobbs)
  • Tracker -- calibrations download automatically at the start of each run (P. Kyberd)
  • Framework -- trigger MC (D. Rajaram)

Schedule¶

Detectors¶

Detector integration (D. Rajaram)¶

• ACTION: Add data_analyzable flag for each detector in post processing to CDB (Detector software heads) #1585, #1689

Tracker (P. Kyberd)¶

• Fix tracker MC no MCS x' 1s.d. deviation bug (P. Kyberd)
• ACTION Fix Pattern Recognition bugs - 50 MeV/c excess, MINUIT misreconstruction at low pt #1807 (A. Dobbs)
• Space-point, track-finding efficiency studies partly blocked by lack of trigger #1182

TOF (D. Rajaram)¶

• Restructure TOF MC Digitizer - part of trigger MC (D. Rajaram)

EMR (F. Drielsma)¶

KL (M. Bogomilov)¶

CKOV (D. Rajaram)¶

• Calibration
• Validate CKOV MC against data

Global Reconstruction (M. Uchida)¶

Monte Carlo¶

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

Geometry and CDB¶

• Want to be able to pull down tracker calibration data at the start of every run (better for online rec)
  • CDB C++ API written, but not yet ready for use

Third party libraries¶

• ROOT6 upgrade (AD) (On Hold)

Online Reconstruction¶

• New online framework should be added to MAUS as a third party (D. Rajaram)
• Software On Call (A. Dobbs)
  • http://micewww.pp.rl.ac.uk/projects/maus/wiki/Software_on-call (SOC wiki)

Batch Offline Reconstruction¶

• GRID MC running
• Offline Rec running with 3.0.1

Infrastructure¶

• Multiple tracks per trigger
• Complete Output API
  • Make OutputCppRoot inherit from IModule
  • No more casting from py_obj* to determine Spill, RunFoooter, RunHeader, JobFooter, JobHeader type?
  • Make base class for Spill, RunFooter, RunHeader, JobFooter, JobHeader
• Make OutputCppRoot work with cpp reducers in general (ok if some specific ones do not)
• Fix the Reducer API to all running multiple reducers in a chain
• Find a way of making the spill and event number accessible through the data structure detector event classes

Performance¶

• Speed improvements for MC
• Multithread MAUS for reggular use, not just online recon (AD, DR)

Event Viewer¶

Documentation¶

• Update tracker (P. Kyberd)

Build system / Version control¶

• Move VCS to git and github
  • https://github.com/mice-software/maus
  • User documentation
  • Developer documentation
  • Jenkins jobs: http://test.mice.rl.ac.uk/view/Release/job/MAUS_release_git/

Analysis¶

• Add analysis cuts to reconstructed data (M. Fedorov, C. Rogers)
  • Add place to hold cuts and bool flags to data structure
  • Add analysis code to correctly set the flags

AOB¶

• MICA analysis package: https://github.com/ajdobbs/mica

Notes¶

Attendance¶

AD, CHunt, JG, PF, PK, MS
MF had connection difficulties

Release Status¶

Schedule¶

Detectors¶

• Tracker
• CHunt will take over PatRec after AD leaves
• CHunt planning on looking at:
  • systematics in track fit
  • can we mitigate dead channels' effect on the recon?
• TOF
  • AD will encourage SW to attend MAUS meetings

Global Reconstruction¶

• AD will encourage MU to attend MAUS meetings

Monte Carlo¶

Geometry and CDB¶

Third party libraries¶

Online Reconstruction¶

Batch Offline Reconstruction¶

Infrastructure¶

Performance¶

Event Viewer¶

• DR has done some analysis into crashes -- SciFiDigit and SciFiCluster may be contributors, MS still thinks MiceModules are causing issues too
• Offline now also crashes when EVReducer is used, MS will try to fix, and send to AD to look at too
• Agreed to focus on making sure EV works offline, online less relevant now due to only limited running time on MICE

Build system / Version control¶

• MS encountered the infamous "Python.h not found" build error, and fixed it, AD requested he puts it on the issue tracker for reference

Analysis¶

AOB¶

• Our thanks to JG for all his hard work, and best wishes for his new career in software development!
• PF and DR will take over AD MAUS duting when he departs in ~2 weeks.
• Next meeting: 1st November 2017
