Investigation of inflow during sawtooth crashes using two-color soft x-ray system in JT-60SA integrated commissioning phase

Nuclear Fusion
An electron-temperature profile of approximately 1 keV at the plasma center, together with its sawtooth oscillation, was evaluated from the bremsstrahlung power spectrum using a soft x-ray diagnostic system during the JT-60SA integrated commissioning ...

Design of JT-60SA Cryodistribution components

Design of JT-60SA Cryodistribution components
JT-60SA is a fusion experiment tokamak device using superconducting magnets to be built in Japan. This joint international project involves Japan and Europe. In this work, we presents the design of cryodistribution and its components which are composed of a main transfer line (TL) and valve boxes (VB).

Effects of poloidal magnetic configurations on expansions of electron cyclotron wall conditioning plasma and hydrogen removal in the integrated commissioning phase of JT-60SA

Nuclear Materials and Energy
Hydrogen (H2) molecules were desorbed from the wall by tokamak discharges with helium (He) working gas. Particle balance analysis revealed that up to the same number of H2 molecules as the injected He atoms were evacuated per He tokamak discharge.
