    SFT/Key4hep Meeting
    ===

    Attendees: Andre, Leonhard, Anna, Mateusz, Carsten, Brieuc, Alvaro, Juan, Juraj, 

    Apologies: Swathi, Benedikt, 

    Date: December 5, 2023

    ## News

    ## Round The Table

    ### Carsten

    ### Juan

    * New release for Key4hep: Alma9, Ubuntu22, CentOS7
        * Conflicts for e.g., ju-pytext needing specific pip range
        * Release with debug symbols?
    * podio QoL improvements: faster podio-dump startup
    * PodioWriter/Reader interface
    * Build with Debug-Symbols
        * Subset of packages with debug symbols
    * Reimplemented downstream builds to get dependencies from spack and then build via for-loop

    ### Mateusz

    * Investigating how to monitor transient data store
    * Fixing typos in documentation

    ### Brieuc

    * Driftchamber implementation: using rotated tubes, instead of intersection solids which was using too much memory
    * Wires are fine, but the gas volume around the wires has a complicated shape. Did not want to use virtual segmentation for this
    * Decided to use ddsim for full simulation for all detectors

    ### Alvaro

    * Vecgeom navigation in tesselated solids is not working
    * Tesselated solids scales with the square number of nodes (e.g., CAD beampipe)
        * Try with incoherent pairs in the beampipe to see the speed
        * Facets are too small in some cases 1e-15 mm

    ### Anna

    * Debug build would be useful
    * Working with OpenDataDetector
    * How to attach two Sensitive Detectors to the same volume?
        * One fast one full simulation

    ### Andre

    * NTR

    ### Leonhard

    * Using iLCSoft Track Reconstruction with the OpenDataDetector
    * There will be ACTS track fits in this year
    * New ACTS geometry model coming soon (TM)

    ### Juraj

    * Storing metadata for event filter
