The outline of following activities in the area of VAMAS TWA-6 will be reported. (1) Establishment of reliable measurement techniques for superconducting wires. 1.1 Critical current measurement in multifilamentary Nb₃Sn wires. 1.2 AC loss measurement in Nb-Ti wires. (2) Establishment of reliable measurement techniques for cryogenic structural materials. 2.1 Tensile measurement at 4.2K in SUS 316 LN, YUS 170 and Ti-Al-Sn alloy. 2.2 Fracture toughness measurement at 4.2K in the same steels and alloy. 2.3 Electrical strain gauge calibration at cryogenic temperatures. Future possible cooperation programs of this area will be also described.
