2. Beryllium capsule Atmosphere: Argon Grades: PF-60, UHP, S-65F Specimen types Tensile: 12 layers of 0.5 mm thick each Bend: 6 layers of 1 mm thick each Compression: fillers in tensile specimen holes Microstructural analysis: fillers between tensile specimens HiRadMat use 1 bend specimen from each layer (will need to be wider ~ 10 mm bend specimen) or add extra 1 mm layer of just HRMT specimens (need to verify effect on peak temperature) Specimens arranged within each layer to achieve all 3 grades at all temperature regimes Total energy loss: ~ 10.41 MeV (including SS windows)

3. Preliminary thermal analysis - Beryllium 20 layers including SS windows
