Stiffener design review

• Robert Becker (ETH Zurich)
• Ashley McDougall (University of Oxford)
• Matthew Brown
• Alex Knight (University of Oxford)

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

Module design discussions

• Ashley McDougall (University of Oxford)
• Matthew Brown

Room: Mulvey Room 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?
