Yi Zhang was born in Shanghai, China. He received his Bachelor-Phys.degree in 1982 at the Jiao Tong-University, Shanghai, his Dipl.-Phys. degree in 1987 and his Ph.D. degree in 1990 at the Justus-Liebig University Gießen, Germany.
He joined the ForschungszentrumJuelich in 1990, dedicating his work to the fabrication and application of High Tc rf SQUIDs. In April 1993 he became awarded the title of an extraordinary professor for modern physics at the University of Peking and in November 1997, he became awarded the title of an extraordinary professor on the field of SQUID technologies at the Jiao Tong-University, Shanghai. In 2001, he spent four months as a guest scientist at the University of California, Berkeley, in Prof. John Clarke’s Group, working on the novel superconductor magnesiumdiboride and developing the first MgB2 SQUID. He became the title of an adviser professor at University Tongji in Shanghai in October 2002. He was one of the co-authors of “SQUID Handbook” edited by John Clarke and Alex. I. Braginski, WILEY-VCH Verlag GmbH & Co. KGaA (2004). Recently, he has been invited as adviser professor at Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, and guest professor at Jilin University (2011). In April 2014, Shanghai government has awarded him with “international cooperation award”. Dr. Yi Zhang has more than 150 publications and about 30 pending or filed patents, and is one of the leading scientists for SQUIDs worldwide. Several of his works were cited in the Book “100 Years of Superconductivity” edited by Horst Rogalla and Peter H. Kes (2011), CRC Press, Taylor & Francis Group.
Abstract:Low temperature SQUID is a modern sensor to measure magnetic field and it is widely used in geophysical、medical and military areas. Prof. Zhang has already focused on SQUID applications for more than 30 years. Recently, he collects his research results and writes a book about how to design a practical SQUID system.
In this talk, he will present three works:
i)a brief and easy-understand introduction about SQUID techniques; 2019年6月3日下午3时；
ii) the parameters in the system and how to suppress system noise; 2019年6月4日上午9时；
iii) the readout circuits. 2019年6月5日下午3时。
