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)¶

• ACTION Evaluate tracker performance in presence of dark current for DEMO
  • Efficiency tools and results
  • Purity tools and results
  • Reconstruction improvements
• Fix tracker MC no MCS x' 1s.d. deviation bug (P. Kyberd)
• ACTION Fix Pattern Recognition bugs that cause loss in efficiency #1807 (A. Dobbs)
  • See Tracker efficiency meeting
• Space-point, track-finding efficiency studies partly blocked by lack of trigger #1182
• ACTION: Fix close to paraxial tracks producing nan output (C. Hunt, P. Kyberd)

TOF (D. Rajaram)¶

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

EMR (F. Drielsma)¶

KL (M. Bogomilov)¶

CKOV (A. Liu, D. Rajaram)¶

• Calibration
• Validate CKOV MC against data

Global Reconstruction (M. Uchida)¶

• Tracking (J. Greis)
  • Primary chain http://micewww.pp.rl.ac.uk/issues/1840
• PID (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 2.8.4

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¶

Notes¶

Attendance¶

A. Dobbs, M. Federov, C. Hunt, P. Kyberd, D. Rajaram, M. Savic

Release Status¶

• 2.9.1 expected next week, after kalman p-value fix is available

Schedule¶

Detectors¶

• Tracker
  • DR will propose to tracker group a "good data" set of criteria for the flag, who will discuss
  • Next tracker software review sometime next week (patrec efficiency efforts on going, focus on fixing longitudinal part of the fit (AD))
  • Kalman p-value fix (first iteration) hopefully ready by end of week (CH)

• TOF
  • TOF2 efficiency is a calibration issue, should be done in a few days (SW)
  • TOF momentum discrepancy - harder, not sure what is wrong (SW)

Global Reconstruction¶

• DR has tried runnning global recon, adds ~ * 4 to run time of standard script, or ~ * 2.5 if use a reduced version
• DR will make a separate standard run script which includes global recon

Monte Carlo¶

• MC run number ("what run does this MC simulate?") still wanted but low priority (DR)

Geometry and CDB¶

Third party libraries¶

Online Reconstruction¶

Batch Offline Reconstruction¶

Infrastructure¶

Performance¶

• DR and AD to discuss how to multithread MAUS for regular use, not just online

Event Viewer¶

• MS has a few issues:
  • Unhandled MiceModules exception
  • EV-based memory leak
  • Seg fault from somewhere outside EV, MS not sure where, will send code to DR to try
  • Style test failure with downloaded HepRepHeader - AD explained how to disable test for that file

Build system / Version control¶

Analysis¶

• Cuts objects coming along, MF will give presentation at CM48

AOB¶

• CM48 - everyone agreed to talks listed above, PK will find someone to speak in his place

• No meeting next week due to CM, so...
• ... Next meeting: 12th July 2017
