Manufacturing of JT-60SA Cryostat Base

Fusion Engineering and Design, 2013
Abstract JT-60SA is a superconducting tokamak to be assembled and operated at the JAEA laboratories in Naka (Japan) [1] . The tokamak has been designed to prepare, support and complement the ITER experimental programme and will be manufactured and operated under the funding of the Broader Approach Agreement (between the government of Japan and the ...

Development of low inductive electric field plasma start-up in JT-60SA

Nuclear Fusion
Plasma start-up experiments have been performed in JT-60SA under ITER-relevant low inductive electric field conditions. A systematic investigation was conducted to identify the key factors that determined the success or failure of start-up.

Core and edge modeling of JT-60SA H-mode highly radiative scenarios using SOLEDGE3X–EIRENE and METIS codes

Frontiers in Physics
In its first phase of exploitation, JT-60SA will be equipped with an inertially cooled divertor, which can sustain heat loads of 10 MW/m2 on the targets for a few seconds, which is much shorter than the intended discharge duration. Therefore, in order to
