Summary of Discussion

1. Open Call for FY25–26 Funding

   • An open call has been announced for FY25–26 funding related to TDAQ activities for FCC.

   • While individual submissions are allowed, there is a strong incentive to submit joint proposals to improve the likelihood of receiving funding, as the total available funding is expected to be limited.

2. Simulation Needs

   • There is a recognized gap in simulation capabilities: while some work has been done by the simulation group, there is currently no digitization step implemented.

   • Digitization is essential for TDAQ efforts, especially for estimating data rates.

   • Full Geant4 simulation exists for the CLD detector, but it's unclear whether other experimental concepts have comparable Geant4 simulations or any digitization implemented.

     • Action: Follow up with European colleagues to clarify the status of digitization for other detector concepts.

3. Potential US Contributions

   • Vertexing Detectors:

     • A proposed approach is to apply both LHC-like (CMS/ATLAS-style pixel digitization) and ALICE-like digitization models to vertex detectors.

     • This would allow estimation of data rates and a study of sensitivity to digitization models.

   • Dual Readout Calorimeters:

     • As these are being developed within the US, collaboration with the development teams was discussed.

     • The goal would be to encourage those groups to implement digitization to enable reliable data rate estimates.

4. Long-Term Goals

   • In both detector paths, a key area of interest is assessing opportunities for triggering and on detector data processing including zero suppression, and how such processing might be implemented.

   • Evaluate the data rates.

   • A detailed understanding of beam backgrounds is also necessary.

     • Action: Investigate the extent to which beam backgrounds are currently integrated into the simulation chain.

Action Items

• Confirm digitization status of other detector concepts with European collaborators.

• Begin prototype digitization for vertex detectors using both ALTAS/CMS-like and ALICE-like models.

• Engage with dual readout calorimeter developers to encourage digitization efforts.

• Follow up on beam background modeling in simulations.
