positive-ion-based NBI systemPLC100 s operationsModification of JT-60U to a superconducting device (so-called JT-60SA) has been planned to contribute to ITER and DEMO. The positive-ion-based NBI system (P-NBI) is required to inject 24 MW for 100 s with 12 units. The P-NBI control ...
A key tool in the machine will be the 7 MW, 9 gyrotrons ECRF system which, as for the 34 MW NBI system, will be available in the Integrated Research Phase. Up to 3 MW of ECRF power will be available in the Initial Research Phase after a staged commissioning. The ECRF system will ...

To achieve this operation, AC power source of the medium voltage of 18 kV and 7 GJ has to be provided in total to the poloidal field coil power supplies and additional heating devices such as neutral beam injection (NBI) and electron cyclotron radio frequency (ECRF). In this paper, the ...
The device will count on ECRH and NBI as auxiliary heating. Potentially dangerous situations that could harm the tokamak structures during operations characterized by low EC absorption cannot be a priori excluded. An estimation of the wall load under direct beam exposure and during plasma operations ...
