====== Telecon Notes July 25, 2018 ====== Attendance: Roger, Bill, Jeff, Toki, Hannes, Jamie, Shaul, Qi Regrets: === Agenda === * Mechanical design of focal plane, {{::20180725_focalplane_progress.pdf|}} (UMN) * Report - Technology Maturation Plan === Notes === * Focal Plane (Qi) * Jeff: beryllium could be something to consider as well, very light * **Check with Tom about Through-wafer vias (AI)** * Jamie: magnetic shielding? Shaul: no, out of scope * thermal conductance of indium bumps seem surprisingly large. **Check thermal conductivity at 100 mK from phonons vs electrons (AI)**
