Progress of the KSTAR tokamak engineering

Proceedings of the 19th IEEE/IPSS Symposium on Fusion Engineering. 19th SOFE (Cat. No.02CH37231), 2002
The KSTAR tokamak is under construction with aim of establishing a scientific and technological basis for an attractive fusion reactor. The KSTAR tokamak system consists of a vacuum vessel, magnet systems, in-vessel components, a cryostat, thermal shields, a vacuum pumping system, and ancillary systems.

KSTAR Tokamak Neutronic Analysis

IEEE Conference Record - Abstracts. 2005 IEEE International Conference on Plasma Science, 2005
Summary form only given. KSTAR, which is to develop the construction techniques of a steady-state-capable advanced superconducting tokamak and to establish a scientific and technical basis for an attractive fusion reactor, is under construction in Korea. High-beta, beam-heated KSTAR deuterium plasmas should produce fusion neutrons.

Radioactivity evaluation for the KSTAR tokamak

Radiation Protection Dosimetry, 2005
The deuterium-deuterium (D-D) reaction in the KSTAR (Korea Superconducting Tokamak Advanced Research) tokamak generates neutrons with a peak yield of 2.5 x 10(16) s(-1) through a pulse operation of 300 s. Since the structure material of the tokamak is irradiated with neutrons, this environment will restrict work around and inside the tokamak from a ...

Conceptual design of the KSTAR Motor Generator

Fusion Engineering and Design, 2011
The Korean Superconducting Tokamak Advanced Research (KSTAR) Superconducting magnet power supply is composed of a Poloidal Field Magnet Power Supply (PF MPS) and a Toroidal Field Magnet Power Supply (TF MPS). When the PF MPS is operated, it requires a large amount of power instantaneously from the KSTAR electric power system.

ECH-assisted startup at KSTAR

AIP Conference Proceedings, 2009
The electron cyclotron heating (ECH)‐assisted startup was successful in the Korea Superconducting Tokamak Advanced Research (KSTAR) first plasma campaign completed in June, 2008. It was observed that the second harmonic EC wave of 0.35 MW was sufficient to achieve breakdown in the ECH pre‐ionization phase, to allow burn through, and to sustain the ...

Second Harmonic Breakdown in KSTAR

AIP Conference Proceedings, 2007
An 84‐GHz electron cyclotron heating (ECH) system is being installed on the KSTAR tokamak. KSTAR adopts ECH‐assisted start‐up for the flexibility and reliability of the KSTAR operation with the plasma breakdown voltage reduced. The available maximum power of the 84 GHz ECH system is presently 500 kW with maximum duration of 2 s.

Overview of KSTAR initial operation

Nuclear Fusion, 2011
Since the successful first plasma generation in the middle of 2008, three experimental campaigns were successfully made for the KSTAR device, accompanied with a necessary upgrade in the power supply, heating, wall-conditioning and diagnostic systems.
