The European Society for Applied Superconductivity (ESAS) announced that it has awarded the 2019 International Applied Superconducting Outstanding Contribution Award to Ma Yanwei, a researcher at the Institute of Electrical Engineering, Chinese Academy of Sciences, in recognition of his outstanding contribution in the field of new practical superconducting wires. This is the first time a Chinese scientist has won the award.
It is reported that the award will be formally presented at the 14th European Conference on Applied Superconductivity, which will be held in the United Kingdom on September 1 this year. The award is awarded every two years, and only one winner is selected at a time. It aims to recognize individuals who have made outstanding innovations and major scientific contributions in the field of international applied superconductivity in the past five years.
Ma Yanwei has been engaged in research on new superconducting materials for a long time. In recent years, he has led a research team to achieve a series of important results in the performance research and development of iron-based superconducting wires.
In terms of performance research, Ma Yanwei's team developed a series of new iron-based superconducting wire preparation processes, and proposed a coordinated control mechanism for the density and grain orientation of iron-based superconducting materials, taking the lead to make the critical current density of the material exceed 100,000 amps per The practical threshold of square centimeters and continued to maintain the international leading level.
In the development of practical materials, Ma Yanwei's team took the lead in developing a multi-core iron-based superconducting wire with low AC loss, a low-cost copper-clad iron-based superconducting wire, the world's first iron-based superconducting joint, and the world's first 100-meter capacity. Grade iron-based superconducting long wires, etc., have strongly promoted the practical process of iron-based superconducting materials.
The ESAS jury commented in the award presentation: "The winners based on a deep understanding and vision of the characteristics and application potential of iron-based superconductor materials, innovatively designed and developed a series of key technologies for iron-based superconducting materials, and developed a high-field critical current. Iron-based superconducting wires that have reached practical levels have become a new milestone for iron-based superconducting materials towards practical applications. "
