HL-LHC BGI Requirements

Europe/Zurich
Present: Gunn, James, Lauren, William.
Discussion on main milestones for 2025:
- Fix conceptual design for impedance studies (end of May);
- Write ECR for HL integration (end of May);
- Fix the SPS BGI-H instrument during TS1 (June);
- HL-LHC Beam Size review (September).
Fixing the SPS BGI-H
Minimum intervention = Install base plate to improve Faraday cage.
To be decided in coming days if/how to modify the RF "window", options:
- Don't change -> See if RF problem fixed by base plate;
- Install RF window same as BGI-V;
- Install RF window like BGI-V, but with additional holes to improve transmission.
William will discuss within ML how to organise the intervention during TS1.
Input for HL-LHC BGI Design
Ionisation electron detector based on a single Timepix4 HPD.
Need to maximise Faraday cage effectiveness by minimising volume of Faraday cage and minimising lengthe of transmission cables.
Pro's / Con's of "classic" desing with feedthroughs on rectangular desing vs. "new" design with a single DSub feedthrough beneath the detector.
Lauren / William to investigate design options.
Gunn will continue to optimise design of the cathode.
Aim to have a first concept by end of May, with a plausible mechanical & electrical desing and reasonable performance.
There are minutes attached to this event.
