Characteristics of disruptions observed in the initial operation phase of JT-60SA
Nuclear FusionDisruption database in the JT-60SA first plasma operation period has been constructed. The disruptions have been divided into three categories based on their characteristics, and the characteristics of each category have been discussed. The most commonly

Superconducting Magnet for the JT-60SA
TEION KOGAKU (Journal of the Cryogenic Society of Japan), 2009 The upgrading of the JT-60U to the JT-60SA has started in a joint effort by the Japanese government (JA) and European commission (EU) under the framework of the Broader Approach (BA) Agreement. The superconducting magnet system for the JT-60SA consists of 18 toroidal field (TF) coils, a central solenoid (CS) with four modules, and six equilibrium field

Commissioning of the JT-60SA helium refrigerator
Journal of Physics: Conference Series, 2017 The JT-60SA project will use superconducting magnets to confine the plasma and achieve a plasma current with a typical flat top duration of 100 second in purely inductive mode. The helium refrigerator has an equivalent cooling power of 9 kW at 4.5 K providing 3.7 K, 4.5 K, 50 K and 80 K for the diverter cryopump, the superconducting magnets, the HTS ...

2D interpolation and extrapolation of discrete magnetic measurements with toroidal harmonics for equilibrium reconstruction in a Tokamak [PDF]
, 2014 International audienceWe present a method based on the use of toroidal harmonics and on a modelization of the poloidal field coils and divertor coils for the 2D interpolation and extrapolation of discrete magnetic measurements in a Tokamak. The method is

Use of massively parallel computing to improve modelling accuracy within the nuclear sector [PDF]
, 2016 The extreme environments found within the nuclear sector impose large safety factors on modelling analyses to ensure components operate in their desired manner. Improving analysis accuracy has clear value of increasing the design space that could lead to
