Summary of Actions¶

Task	Person	Added	Issue Number	Comment
Fix Pattern Recognition bugs: 50 MeV/c excess	C. Hunt	06/01/16	#1807	to be verified after next reprocessing
MINUIT misreconstruction at low pt	C. Hunt	06/01/16	#1807	in progress
Fix low TOF2 efficiency	S. Wilbur / V. Pec	31/03/2017	#1912

Release status¶

• Current release = 3.1.2

• Targets for next major release, 3.2:
  • New version of the cuts data structure object (Ajit)
  • Fix low TOF2 efficiency (S. Wilbur, V. Pec)
  • Fix TOF momentum discrepancy (S. Wilbur, V. Pec)
  • Event Viewer Reducer (M. Savic)
  • Update Globals documentation (Melissa and Chris R.)

• Targets for future release:
  • Multithreaded MAUS (D. Rajaram)
  • Tracker -- purity analysis code (C. Hunt)
  • 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)¶

• Pattern recognition:
  • ACTION Fix Pattern Recognition bugs - 50 MeV/c excess (C. Hunt)
• Track fit:
  • ACTION MINUIT misreconstruction at low pt #1807 (C. Hunt)
  • Lots of error messages coming out from MINUIT (i.e. <Minuit2>: MnGlobalCorrelationCoeff: inversion of matrix fails): real concern or just annoying?

• Old actions:
  • Space-point, track-finding efficiency studies partly blocked by lack of trigger #1182
  • Fix tracker MC no MCS x' 1s.d. deviation bug (P. Kyberd)

TOF (D. Rajaram)¶

• TOF inefficiency:
  • release DT cut to 2ns. Improvements but some additional effects may come from the calibration (Viktor)
  • DT offset: mostly in outer slabs. Improving the calibration (Scott)
• 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/C. Rogers)¶

• ACTION: new information in the work book and in the documentation
• Verbosity in the log coming from killed tracks #1955
• Globals memory usage: improved, to be verified with imminent reprocessing
• Globals: implement two debug levels
• Melissa: encouraged to have the global tracks done independently upstream and downstream of the absorber and next matched together. Different from what Chris was initially implementing.

Monte Carlo¶

• Monte Carlo trigger (D. Rajaram) #1182
  • Restructure TOF Digitisation and incorporate MapCppTrigger (D. Rajaram)
• ACTION Run number in MC

Geometry and CDB¶

Geometry:

• Wedge absorber: Pavel to provide a GDML.
• LH2 absorber during the filling needs to be defined
• Durga has fixed several issues

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 (On Hold)

Batch Offline Reconstruction¶

• Massive logging (O(root output)) had to be sorted out.
• GRID MC: on hold
• Offline reconstruction:
  • imminent with release MAUS-v3.1.2 in the MLCR
  • long term solution: jobs on the GRID (https://micewww.pp.rl.ac.uk/projects/computing-software/wiki/Grid-PC180206). Fixed been made to download scifi maps and calibrations to a non-maus area.
  • Ready to be tested on the GRID. dCache will host the semaphore instead of offrec01.
  • Future: move datamover out of miceNet into PPD. Will be a new box.

Infrastructure¶

• OutputCppRoot
• 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 regular use, not just online recon (the online reconstruction is multithread and is using MAUS as a third party)

Event Viewer¶

• Ready for the next release. Documentation (workbook) updated.

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¶

• Analysis cuts structure (A. Kurup):
  • Upgrade of the work https://micewww.pp.rl.ac.uk/attachments/download/9662/2018_01_10_Cuts_Upgrade_Specification-2.pdf
  • New structure: Ajit will implement a new class to store additional informations on the cuts and a new mapper, to work in parallel with the current one. The old class will be deprecated once the job is done. Any objection on that?

AOB¶

• MICA analysis package: https://github.com/ajdobbs/mica
  • Is C based. Not all the users would take advantage of it.
