Geometry¶

• Handling field maps in MAUS (#1810)

G4BeamLine¶

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¶

• MAUS running fails on GRID (#1815)
• 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 1.4.0

Infrastructure¶

• InputCppRoot still using JSON (and so super slow) (D. Rajaram) (#1814)
• Fix geometry test which randomly produces large SOAP error (R. Bayes)
• Fix problems when setting header_and_footer_mode to "dont_append" (C. Rogers, C. Pidcott)
• 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
• * ACTION* A. Dobbs to kick off discussion on online EV with Y. Karadzhov before next meeting

Documentation¶

• Update tracker (C. Heidt)

Release Status¶

A. Dobbs will release 1.5.0 when tracker group provides MC fixes

Schedule¶

Detectors¶

• All detectors
  • ACTION: Urgently need validation plot from detectors to integrate with geometry & reconstruction to make sure geometry+reco is OK
• KL
• Ckov
• EMR
• Tracker
  • Star problem (fiber lengths in geometry), large residuals between reco and MC truth.
  • Sliding residuals is the remaining issue.
    • C. Hunt has pushed some fixes - now in MAUS. Heidt working on geometry solution for other half of the problem.
  • M. Uchida expecting to get tracker online plots updated in next few weeks
    • These are efficiency and validation plots, not intended for online reco but DR thinks it's worth maybe having some subset of it for online reco

• TOF

Global Reconstruction¶

• Global team will try to provide a branch for merging in their code before the next meeting.
  • J. Greis - testing of global tracks is blocked by tracker MC. But ready to push code de/dx into MAUS
    • built on Jenkins, but seeing some application test failures on private machine. Will create issue and if MAUS man is happy JG will propose a merge

Monte Carlo¶

Geometry¶

• RB waiting for alignment corrections from FD before releasing new geometry
• CHeidt asked RB to check with him before final release of geo, since tracker group may have some more fixes.
• We need detector validation to integrate with geometry to ensure that the geometry representation is OK for MC and data reconstruction (see above)

G4BeamLine¶

RB will provide a link to non-grid-hosted G4BL chunks for people interested in testing

Online Reconstruction¶

Batch Offline Reconstruction¶

• DR waiting for tracker fixes and new release of MAUS before proceeding with MC & reprocessing on MLCR
• D. Rajaram will continue working with D. Maletic to get full GRID MC back up again.
  • DM getting up to speed, getting certificates etc to poke around on GRID.

Infrastructure¶

• MAUS running fails on GRID. Portability issue related to numpy build. Issue created.
• Reco quality: JM creating a table for reco quality flags (~2 weeks), DR working on integrating TOF quality, will test with table on preprod

Performance¶

MC speed needs to be addressed when we find time.

Tools¶

AOB¶

• Software workshop at CM44 likely to be on the Friday afternoon, A. Dobbs to confirm

Next meeting: 15:00 GMT, 17th Feb 16
