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)
  • 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)

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)

Online Reconstruction

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

Event Viewer

Documentation

  • Update tracker (P. Kyberd)

Build system / Version control

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. Fedorov, J. Greis, C. Hunt, P. Kyberd, D. Rajaram, M. Savic

Release Status

Schedule

Detectors

  • Tracker
    • Validation criterion for good event required from tracker to give to DR - PK will talk to MU (PK)
    • Tracker NaN - fix by next release (CH)
    • Work continuing on efficiency improvement, next steps:
      • Refactor least squares fit to try to avoid nturns calculation
      • Enhance efficiency calculation to deal with non-ideal events if possible

Global Reconstruction

Monte Carlo

Geometry and CDB

Third party libraries

  • AD continuing to push for ROOT6 upgrade, progress tracked at #1919

Online Reconstruction

Batch Offline Reconstruction

Infrastructure

Performance

Event Viewer

  • DS tracker shifted 10cm, problem for MS. How do we handle two different detector geometries? 2 potential solutions:
    • Use MiceModules
    • Keep hard coded tranforms, add a lookup table between run number and correct transforms
    • MS favours latter option.
  • Some stability issues when used in OnRec, symbolic link solution looks promising

Build system / Version control

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

  • CR and MF struggling to build MAUS on the RAL PPD cluster, AD will try too (gcc build issue)
  • PK struggling to build MAUS on laptop, will visit AD at IC to look at

Next meeting: 5th April 2017
