Roundtable

Doga

- Working on Fast Jet class for ACTS. This will be in the Examples and Plugins in ACTS
- The PR is already ready and can be reviewed

Andreas Stefl

- truth tracking for electron finding studies in ACTS
- inefficiencies in odd (unexpected)
- SP were sorted by time - it flips in pix the space point - removed now
- particles can slip through layers in odd without hitting any surface - but not to be touched now
- restriction on the pixel measurements and filtering out insufficient measurements
- changes in truth seeder and particle seeder 
- odd layout not tuned, which is possible cause of the inefficiency

Carlo Vani

- Recent plots (regarding trigger?) requested by EFTracking are mostly addressed 
- Definitions in IDPVM efficiency plots are ambiguous: understanding the denominator?
- Discussion on regional reconstruction with CPU VS. GPU

Alex

- ACTS spack installation, with help of Dimitra building a full chain of muons with Chisquare fitter for muons
- Can generate muon SP and convert them into measurements
- Importing geometry is the next step
- Some parts are missing from the full chain
- Incoherent input data - had to add blanks for testing purposes

Got almost through, setting up a prototype chain to reconstruct muon spce points with the gx2f.

Neza

Making CTD plots. Timing constraints CPU vs GPU.

- Debugging for the inefficiency gap 
- Muons are looking fine
- Timing comparison for CPU VS. GPU - breakdown into pie charts with suggestion from Noemi
    - Comparison between C-230 and G-230 , C-230, G-230 and G-050

Mikkel

- GNN on pixel only for seeding in ACTS/ATHENA
- Compiles but doesn't run - debugging

Started QP with gbts

Attila

- Report for DUNE experiment - they are writing a conceptual design report for their software - preliminary report is done
- Working also on Analysis I/O code - readability of ntuples - smaller files - faster writing

 

PF

Tune trackfinding.

- Tuning of track finding: legacy track finder uses strip width as error, acts strip pitch
- Stripcalibrator added (with Noemi) to do ascts-based track finding
- Efficiency checks with strip pitch VS. strip width: 
    - chi2 changed 50->100
    - Technical efficiency: Improvement in barrel region by 1%
    - Physics efficiency: almost matching C-000 in the barrel
    - In technical efficiency pions are forced to traverse into strip but in the physics efficiency pions get absorbed
    - Cost: higher fake rate 
    - No tuning at chi2 yet - fake rate VS. track pt

Luthien

- Starting with neural network for pixel splitting classification
- Converting Max (Hart)'s model into onnx and implementing it in Athena

Dimitra

- Seeding for new small wheel
- Monitoring plots that are added are too small, works on optimizing this
- Change of names of some algorithms for clarification for the plots
- In the geometry there are unmatched simhits on STGC layers 
    - Simhits are not right on the layer, but a step ahead (non-zero z value is observed )
    - Possible reason is with post processing with Geant4 

Working with Alex on drift circle fit with the gx2f.
