Attendance: Gordon, Andrey, Emma, Maurice, Kamil, Alex, Peter S. Dan, Simon

Meeting recordings:

• Introduced Kamil
• IR shielding presentation from Emma, discussing joint details
  • Joint details: No resolution yet, material thicknesses and assembly an issue
  • Squid card: sufficient space for up to 64 (?) channels
  • Cabling/Electronics accommodation: Needs larger diameter to be able to run ribbon cables both on both neck sizes. Ideally increase inner diameter (cold shield), reduce distance to still shield
  • Need to update the simulation, there is quite some difference in weight between what is in the latest sim and
  • Separate the IR shielding flange from the gamma-ray copper shield
  • Include reasonable cosmogenic activation

• Gordon will contact Sylvia because of DocDB
