• Presentation of Ariel on the thematic of the working group described as a sharing platform between all different actors involved in the loop from Nb3Sn strand to magnet either in modelling and/or gathering experimental data. The goal of the working group is to create connections and common interests in order to close the loop (or at least build some bridges between the different scales).
• Proposition as a first activity together to gather a complete and organized literature database.
• Each institute representative presented their current work on the subject:
• CEA: Strand tensile stress characterization, compression tests on cable stacks, heat treatment studies on strands, stacks, coils, modelling of strand and cable stacks with Cocascope.
• PSI: Box program mostly toward bounding and resin effects, compression box for transverse stress, 10-stack studies with ETHZ, modelling with MagNum
• ETHZ: Research on epoxy and 10-stack characterization with PSI
• CIEMAT: Magnet design and relaying mostly on literature for coil composite
• CERN: 10-stacks compression tests towards standard measurements, heat treatment studies, magnet models validated with magnet testing (SMC, MQXFS,...)
• INFN: Magnet design and relaying mostly on literature for coil composite
• A small discusion took place highlighting the difference between perfect models and models you use in magnet design at the end. Also about the difference between what is measured in characterization or experiments and what is input in the models: like 2 different languages. More connections are needed.
• About the modus operandi, we could meet once every month either for a forum type meeting with sharing of results/status or as a discussion around a specific topic. This topic will be announced before the meeting.
