Sam DAVIS (F4E), Project Leader as of December 2023

Sam Davis started work at the Culham Centre for Fusion Energy in the UK, working first on materials and magnet development and then on tokamak upgrade projects.

He joined the JT-60SA project in 2010, working for Fusion for Energy in Garching, Germany.  He first followed the manufacturing of the cryostat base on which the tokamak rests and its delivery from Spain. He was then fully occupied in the design, manufacturing and assembly of the toroidal field magnet. After launching a range of enhancement projects he moved to Naka, Japan in 2020.

During 2020-2023 he supported the integrated commissioning of the JT-60SA tokamak and the modifications necessary to reach the first plasma. He was appointed as JT-60SA Project Leader in December 2023.

Koji TAKAHASHI (QST), JA Home Team Leader

Koji Takahashi is a research scientist on microwave heating technology for fusion devices. In 1994, he started his carrier at Japan Atomic Energy Research Institute, currently National Institutes for Quantum Science and Technology (QST) to join the development of high power RF sources, so-called gyrotron for fusion plasma heating.

He also involved with the development of transmission line components such as antennas and waveguides for JT-60U and ITER.

He was responsible for design and development of the RF power injecting antenna for ITER from 1998 to 2015 and completed the antenna reference design. He also took the responsibility of ITER gyrotron procurement from 2016 as a group leader of RF heating system and completed manufacturing of all eight gyrotrons.

He has involved in JT-60SA project since 2021 as the Deputy Director, Department of Tokamak System Technology and managed the project as JA Home Team Project Manager since 2022.
