THEVA

THEVA

Founded in 1996 as spin-off from the Technical University of Munich, THEVA has been specializing in high temperature superconductor (HTS) materials, coating- and process technology. Since 1998 THEVA has been engaged in HTS coated conductor development and established an independent and proprietary fabrication route for coated conductors. THEVA’s technology is protected by 39 patents (30 granted, 9 pending) from 13 individual patent applications.

Since its foundation THEVA has a long track record in the HTS coatings, quality control and equipment engineering. Since 2012 THEVA has invested €10 Mio for establishing the biggest pilot production facility for HTS coated conductors in Europe. Currently, THEVA has 45 employees and 1700 m2 of operation space at Ismaning, close to Munich airport.

Coated conductor processes are continuously improved and developed with respect to yield and performance to match the needs and technical specs of special applications.

Dr. Markus Bauer is a senior expert in high temperature superconductors and studied physics at the Technical University Munich (TUM). He received his PhD at the physics department in 1998 for the development of bi-axially textured buffer layers on metal ubstrates. He is one of the founding members of THEVA. After his PhD he spent three years as post-doc assistant at the TUM, before he was hired by Thyssen-Krupp Transrapid as project leader. For more than eight years he worked as project manager in the fields of electric drives and inductive power transmission before he returned to his roots and joined THEVA in 2010 where he first was responsible for the development of the coated conductor production line and now leads the business development. In the project he will be the project leader for the activities of THEVA.

Dr. Veit Große studied physics and received his PhD from the Friedrich-Schiller-University Jena in 2010. After that he joined THEVA and has been responsible for process development in field of the coated conductors and is now the head of the R&D department. He is an expert in our coated conductor fabrication technique and the mechanical and electrical properties of the coated conductors. In the project he will coordinate the optimization of the coated conductors.

Dr. Eike Nanocha studied materials science and received his PhD from the Technical University of Berlin in 2012. He joined THEVA in 2012 and worked on the HTS deposition on short length with our laboratory systems. When the pilot line went into operation he became responsible for the HTS deposition process with this line. In the project he will focus on the improvement of the HTS deposition process.

Stefan Furtner studied Physics at the Technical University of Munich and received his Diplom in 1997. He joined THEVA in the same year and started to develop devices for characterization of HTS coatings on wafers and tapes. Today he is responsible for the development of measurement devices in general and also measurements with the THEVA owned hall scanning device Tapestar. In the project he will be responsible for the tape characterization and determination of the homogeneity of the tapes.
