Auxiliary Plant – Control System
The supervisory control system and data acquisition system (SCSDAS) has the following functions:
- plant monitoring;
- discharge sequence management;
- plasma real-time control;
- device protection;
- discharge result data archive, storage, and database management.
There is a separate safety interlock system to avoid inappropriate access to the plant. This independent system is monitored by the SCSDAS.
The supervisory control and data acquisition system of JT-60U has been modified so that various kinds of advanced tokamak experiments can be performed more flexibly and efficiently. The modifications include allowing for the significantly longer discharge time, new diagnostics and control coils, and the superconducting magnets, their power supplies and cryoplant.
