====== Engineering Meeting Oct 22, 2024 ====== Time: 8am PT/11am ET/5pm CET Zoom link: https://uzh.zoom.us/j/5166204490?pwd=VUt1VmFLVmJsYTExeXJka0JwbUlIQT09 Attendance: Agenda: * Alex - Ancient Lead Sims * It seems only a few hundred kg of ancient Pb, not all Edelweis is low in Pb210 * Changing inner Pb layer has rather small effect compared to clean Cu * Estimate impact of cryogenic cooper as function of wall thickness * Check dimensions from drawings and double check both dimension * Andrey will send step file of complete assembly * Emma - Thermal Modeling Update * Thermal contraction modelling: * Neck will not displace more than 0.2mm * Upper and payload cannister both less than 1mm * Vertical displacement up to 4mm * Note from comment: all flanges deflection less than 1mm * Mixing chamber heatloads can be well controlled * HEMTs on the CP, their heat loads are high, can lead to large heat loads exceeding 50mk * We need to check with Julie * Cryo CDR * AOB
