Equilibrium Reconstruction and Its Integration in J-TEXT

Plasma Science and Technology, 2016
The equilibrium fitting code (EFIT) and its application in the J-TEXT tokamak are integrated by the Matlab language. The function of analysis and visualization to the results is added. In addition, the experiment data measured by soft X-ray (SXR) are used to calculate plasma equilibrium as a constraint condition.

J-TEXT distributed data storage and management system

Fusion Engineering and Design, 2018
Abstract As fusion experiment goes to steady state and high-performance data acquisition system been developed, traditional storage solutions cannot cope with the needs of fusion experiment data storage. Distributed file systems such as Lustre are being adopted by more and more facilities.

The timing system on the J-TEXT tokamak

Fusion Engineering and Design, 2014
Abstract This paper describes the timing system designed to control the operation time-sequence and to generate clocks for various sub-systems on J-TEXT tokamak. The J-TEXT timing system is organized as a distributed system which is connected by a tree-structured optical fiber network.

Towards advanced divertor configurations on the J-TEXT tokamak

Plasma Science and Technology, 2022
Abstract Developing advanced magnetic divertor configurations to address the coupling of heat and particle exhaust with impurity control is one of the major challenges currently constraining the further development of fusion research. It has therefore become the focus of extensive attention in recent years.

The vacuum system of the J-TEXT tokamak

Plasma Devices and Operations, 2009
A new vacuum system is designed and developed on the Joint Texas Experimental tokamak (J-TEXT), which consists of two pumping stations, a Taylor discharge cleaning (TDC) system and gas puffing. With this system, the vacuum vessel of the J-TEXT tokamak can easily reach the vacuum conditions which allow the operation of the machine.

Observation of runaway electrons by infrared camera in J-TEXT

Review of Scientific Instruments, 2016
When the energy of confined runaway electrons approaches several tens of MeV, the runaway electrons can emit synchrotron radiation in the range of infrared wavelength. An infrared camera working in the wavelength of 3-5 μm has been developed to study the runaway electrons in the Joint Texas Experimental Tokamak (J-TEXT).

Measurement of the edge plasma rotation on J-TEXT tokamak

Review of Scientific Instruments, 2013
A multi-channel high resolution spectrometer was developed for the measurement of the edge plasma rotation on J-TEXT tokamak. With the design of two opposite viewing directions, the poloidal and toroidal rotations can be measured simultaneously, and velocity accuracy is up to 1 km/s.

Electron cyclotron emission radiometer upgrade on the J-TEXT tokamak

Review of Scientific Instruments, 2016
To meet experimental requirements, the J-TEXT electron cyclotron emission (ECE) diagnostic is being upgraded. The front end antenna and transmission line have been modified and a new 8-channel W-band detecting unit has been developed. The improved ECE system will extend the frequency range from 94.5-124.5 GHz to 80.5-124.5 GHz.
