WG Charge and Priorities

Current Priorities:

  • Continue to support the detector design and integration with services.
  • Evaluate the differences between the engineering and simulation designs and lead the discussion on how to address these differences, in conjunction with the TIC.
  • Continue to support the development of background modeling and implement its timing structure in physics and detector simulations, together with the Background Task Force.
  • Embrace streaming readout in simulation, using it as the default data format and enabling the capability to stream the continuous readout of the detector.

Highlights

  • Key achievements and milestones.
    • Geometry update and detailed DD4hep implementation for all sub-detectors - in agreement with geometry database
    • Simulation to CAD model (step file) conversion
    • Begin of the evaluation process of simulation and engineering designs

​

  • Major impacts and successes.
    • Maintenance of the interface for root geometry to step file conversion (an npsim tool)
    • Discussions on the progress of CAD model to simulation conversion
    • Supports on the digitization improvements (discussions on BTOF hits)

Opportunities with Additional Workforce

  • Development on detector geometries and digitization
  • Background modeling and implementation
  • Geometry visualization (DAWN, OnShape, or other visualization tools)
  • Manual creation of CAD drawings from the simulation models
  • Automated process for the evaluation between simulation and engineering design

​

​

  • Consequences of Insufficient Workforce
    • Till a more automated process is developed, we need to continue the process of manually creating CAD drawings from simulation geometry. Without additional workforce, this process can be tedious and hold up expertise that can better used for more advanced tasks.
    • Background modeling and implementation requires efforts and additional workforce, without it the physics simulations would not be rigorous
