- Created Solder Wire (part): "Joins probe wiring, connectors and coil leads away from the sample's voltage path, because tin-lead solder superconducts below about 7 K. Flux-cored Sn63/Pb37 wire about 0.8 mm in diameter for joints that will be cooled, since tin-rich lead-free alloys can turn brittle at cryogenic temperatures."
