Status of ECRH project on EAST Tokamak

AIP Conference Proceedings, 2014
A 140GHz electron cyclotron resonance heating and current drive (EC H&CD) project for EAST Tokamak is launched in 2011 with a total power of 4MW and pulse length of 100 s. The main objectives of the system are to provide central H&CD, assist start-up and control of MHD activities.

Pellet injectors for EAST and KSTAR tokamaks

Fusion Engineering and Design, 2017
Abstract The paper presents high frequency pellet injectors developed for edge localized mode mitigation and plasma fuelling of the EAST and KSTAR tokamaks. Each pellet injector is able to inject solid deuterium or hydrogen pellets at steady state mode.

Analysis of uncertainty in equilibrium reconstruction in the EAST superconducting tokamak

Review of Scientific Instruments, 2013
The analysis of uncertainties of magnetic measurements in equilibrium reconstruction is carried out on the EAST (Experimental Advanced Superconducting Tokamak) tokamak. It is shown that uncertainties of magnetic diagnostics are about 0.2% and 10 mWb for flux loops and 0.6% and 20 G for magnetic probes.

Fast reciprocating probe system on the EAST superconducting tokamak

Review of Scientific Instruments, 2010
A new fast reciprocating probe system (FRPS) has been built and installed on the outer midplane of the EAST tokamak to investigate the profiles of the boundary plasma parameters such as electron density and temperature. The system consists of a two-stage motion drive mechanism: slow motion and fast motion.

Observation of a strange MHD phenomenon on EAST tokamak

Physics Letters A, 2010
A strange magnetohydrodynamic (MHD) phenomenon has been observed on EAST tokamak. The waveform of the MHD oscillations is similar to that of fishbone mode. The observation and analyzing results suggest that the appearance of the strange oscillations is associated with intensive impurity radiation.

The magnetic field configuration measurement on EAST tokamak

Fusion Engineering and Design, 2009
Abstract The magnetic field configurations of poloidal field (PF) and toloidal field (TF) are the base of tokamak plasma operation. They are determined by the parameters such as positions and structures of PF and TF coils. Parameters of TF and PF coils of a new fully superconducting tokamak with non-circular cross-section EAST will change when the ...

A digital long pulse integrator for EAST Tokamak

Fusion Engineering and Design, 2014
Abstract A digital integrator has been developed to be compatible with the long pulse plasma discharges on the Experimental Advanced Superconductor Tokamak (EAST), in which the induced signal is modulated by a chopper, and a field programmable gate array (FPGA) in the 16-bit digitizer is used to realize the digital integration in real time.

Diagnostics for first plasma study on EAST tokamak

Physics Letters A, 2008
Abstract The first plasma was obtained in the EAST on September 26th, 2006. Single-null (SN) and double-null (DN) diverted plasmas were achieved successfully in the EAST tokamak on January 22nd, 2007. The employed plasma diagnostics for first plasma study of EAST are as follows: a vertical one-channel far-infrared (FIR) hydrogen cyanide (HCN) laser ...

Design and Analysis of the Thermal Shield of EAST Tokamak

Plasma Science and Technology, 2008
EAST (Experimental Advanced Superconducting Tokamak) is a tokamak with superconducting toroidal and poloidal magnets operated at 4.5 K. In order to reduce the thermal load applied on the surfaces of all cryogenically cooled components and keep the heat load of the cryogenic system at a minimum, a continuous radiation shield system located between the ...
