ATHENA-ACTS Weekly Meeting

Monday 24 Jan 2022, 10:30 → 11:30 US/Eastern

10:30 → 10:50 Full reconstruction for B0 Tracker

The non-standard electron beampipe shape is holding off the full ACTS reconstruction. The new cylindrical geometry will be available in ACTS soon, then Sakib and Wouter can work on corresponding tests/validations.

Speakers: Andreas Salzburger (CERN), Sakib Rahman (University of Manitoba), Wouter Deconinck

10:50 → 11:10 Realistic seeding

Yue-Shi implemented the realistic seeding with ACTS v13. Wenqing tested its performance with single pion. The resolution looks reasonable except at the low momentum region and the very forward/backward region.

Speaker: Wenqing Fan (Lawrence Berkeley National Laboratory)

11:10 → 11:30 Material map optimization

For now the material map is generated manually for each detector version. The possibility of optimizing material map binning automatically via machine learning was mentioned. Another useful feature for ACTS to enable a pre-defined volume boundary for mapping. That requires pre-defining ACTS volume with DD4hep instead of having ACTS navigation handle it automatically.

Speakers: Andreas Salzburger (CERN), Corentin Allaire (CERN), Shujie Li (Lawrence Berkeley National Lab), Wenqing Fan (Lawrence Berkeley National Laboratory), Wouter Deconinck
