Analysis of JT-60SA operational scenarios
Analysis of JT-60SA operational scenariosJT-60SA reference scenarios have been simulated with one-dimensional transport codes to assess the stationary state of flat-top phase and provide a profile database for further physics studies and diagnostics design. In this paper we present results obtained with ASTRA, CRONOS, JINTRAC and TOPICS codes equipped with Bohm/gyro-Bohm, CDBM and GLF23 ...

Laser-aided diagnostics of JT-60SA
Laser-aided diagnostics of JT-60SAJT-60SA is currently the world's largest superconducting tokamak. It accelerates the realization of fusion energy by supporting ITER exploitation and complementing it in addressing key physics and engineering issues for DEMO reactors. The main targets of JT-60SA are breakeven-equivalent high-temperature deuterium plasmas and high-β steady-state plasmas.
