First Engineering Commissioning of EAST Tokamak

Abstract

Experimental Advanced Superconducting Tokamak (EAST) is the first fully superconducting tokamak. The first commissioning started on Feb. lSt of 2006 and finished on March 30th of 2006 at the Institute of Plasma Physics, Chinese Academy of Sciences. It consists of leakage testing at both room temperature and low temperature, pumping down, cooling down all coils, current leads, bus bar and the thermal shielding, exciting all the coils, measuring magnetic configuration and warming up the magnets. The electromagnetic, thermal hydraulic and mechanical performance of EAST Toroidal Field (TF) and Poloidal Field (PF) magnets have also been tested. A l l sub-systems, including pumping system, cryogenic system, PF& TF power supply systems, magnet instrumentation system, quench detection and protection system, water cooling system, data acquisition system, main control system, plasma control system (PCS), interlock and safety system have been successfully tested.

Investigation of lower hybrid wave coupling and current drive experiments at different configurations in experimental advanced superconducting tokamak

“…The superconducting coils can create and maintain a toroidal magnetic field, B t , up to 3.5 T in steady state. 13 The key components of EAST are 14 superconducting poloidal field (PF) coils, current leads and superconducting bus-lines, vacuum vessel, thermal shields, cryostat, divertor, and invessel components. It can run in the configuration of limiter, single null divertor, or double null divertor.…”

Kinetic equilibrium reconstruction on EAST tokamak

“…In this paper, the EFIT code [1,2] is used to get the reconstructed equilibria on EAST tokamak [8]. EFIT is an efficiency code to reconstruct the equilibrium.…”

Solid lubrication with MoS2-Ti-C films for high-vacuum applications in a nuclear fusion experimental device

“…Experimental advanced superconducting tokamak (EAST) is the first fully superconducting tokamak fusion experimental device, which is built in China (Yuanxi et al , 2006; Wu, 2007; Wan et al , 2010). The former records of EAST physical experiments indicate a fact that more than 30 per cent of shutdown and maintenance is caused by the damages of small pieces inside the vacuum vessel because of huge heat flux (Luo et al , 2007; Song et al , 2010).…”
