TWA 16
Superconducting Materials
This TWA on superconducting materials was established in 1993, following the separation of the former TWA6 on Superconducting and Cryogenic Structural Materials into two separate TWAs because of the increased growth in technical activities resulting from the discovery of high temperature superconductivity in oxides.
A close liaison had been established with the International Electrotechnical Commission (IEC) TC90, Superconductivity, to facilitate the entry of VAMAS output into international standards.
Further work in TWA16 on high temperature superconductors is strongly supported in North America, Japan and Europe and has the objective of the establishment of reliable measurement methods for superconducting critical parameters, such as critical current, critical temperature, critical field and ac loss, through inter-laboratory comparisons. The work is supported by complementary studies on reliable measurement methods for:
- Stress- strain effect
- Superconducting critical surface
- Relevant physical properties
- Theories and terminology
Projects
- Measurement method for critical current of oxide superconductors under tensile load
- Critical current measurement in MgB2 superconductors”
- Room Temperature Tensile Test for MgB2 superconductive wires
- Surface resistance measurement of superconducting thin films
