Outer Pixel Engineering Design Review Meeting

2 Nov 2026, 10:00 → 3 Nov 2026, 18:00 Europe/Zurich

Oxford

Meeting https://cern.zoom.us/j/4528742764?pwd=HuTN2QQTIWGcus0e1oxIfm5n7Tvbn9.1

Monday 2 November

10:00 → 18:00 Ladder production overview

Speakers: Alex Knight (University of Oxford), Ashley McDougall (University of Oxford), Robert Becker (ETH Zurich)

13:00 → 14:00 Lunch

Tuesday 3 November

11:00 → 13:00 Stiffener design review

Adam (Brick Kiln Composites) will also join via zoom: https://cern.zoom.us/j/4528742764?pwd=HuTN2QQTIWGcus0e1oxIfm5n7Tvbn9.1

Topics of interest:

• Current design proposed by Adam/Alex. Status of prototypes? Any concerns with fabrication? Any concerns with stiffness? Where will the mechanical strain be forced through, the interposer flex? Okay with this?
• Other design styles we want to consider, e.g. extending all the way to the endpiece flex somehow, such that it's clamped down at the end.
• Vertex stiffener design from Robert?

Speakers: Alex Knight (University of Oxford), Ashley McDougall (University of Oxford), Matthew Brown, Robert Becker (ETH Zurich)

13:00 → 14:00 Lunch

14:00 → 17:00 Module design discussions

Topics of interest:

• End-ring redesign to ensure connectivity
• End ring alignment
• Module assembly: any modifications needed?
• Mounting in QC box, any improvements to be made?
• Cooling okay?
• Cabling & connectors -reorientation?
• Plans for 2027, timeline for redesigns? (Largely depends on collaboration goals which will be decided in December, but we can discuss options).

Meeting organisation: what will be discussed between "production"/"installation"/Robert's engineering meeting?
