What’s New

The Chinese Academy of Sciences has reported that the Experimental Advanced Superconducting Tokamak (EAST) at the Institute of Plasma Physics in Hefei has achieved an electron temperature of over 100 million degrees in its core plasma during a four-month experiment carried out earlier this year in collaboration with domestic and international colleagues.

Power injection exceeded 10 MW, and plasma stored energy reached 300 kJ after scientists optimized the coupling of different heating techniques (lower hybrid wave heating, electron cyclotron wave heating, ion cyclotron resonance heating and neutral beam ion heating). The experiment utilized advanced plasma control and theory/simulation prediction.

Research at EAST on physics and technology issues under steady-state operational conditions is directly relevant to ITER. Recent experiments on plasma equilibrium and instability, confinement and transport, plasma-wall interaction, and energetic particle physics have demonstrated long-time scale, steady-state H-mode operation with good control of impurity, core/edge MHD stability, and heat exhaust using an ITER-like tungsten divertor.

Another Highly Exceptional Load (HEL) passes through the six-kilometre-long channel (the Canal de Caronte) that leads from the Mediterranean into the inland sea Étang de Berre through the town of Martigues.

The load consists of four transformers—one poloidal field coil rectifier procured by China and three central solenoid converters (89 tonnes each) procured by Korea. All four are "step down transformers" that lower the 66 kV tension to a few kilovolts before the AC current is transformed into DC to be fed to the magnets. The HEL convoy will begin its land journey on Wednesday and is expected at ITER in the wee hours of Friday. Three more poloidal field coil rectifiers, stored in DAHER facility in Berre, will hit the road on Wednesday 28 November to be delivered at ITER the following Friday.
