Diagnostics play essential roles both in understanding of the plasma physics and in control of the plasma itself. JT-60U has plenty of developments and thus experiences in concepts of the real-time feedback control. The parameters concerned are averaged electron density, neutron emission rate, plasma stored energy, central electron temperature, temperature gradient, temperature fluctuations, current density profile, plasma radiation, outer gap distance, neutral gas pressure, etc., and those combinations. In JT-60U, production of high-performance fusion plasmas and their sustainment owed to such the real-time feedback control. In this paper, the overview of diagnostics equipped for the real-time feedback control in JT-60U is presented.
