KSTAR thermal shield

Fusion Engineering and Design, 2009
The thermal shield intercepts thermal radiation from the components at room temperature to superconducting magnet at 4.5 K. The thermal shield of KSTAR is divided into three categories: vacuum vessel thermal shield, port thermal shield, and cryostat thermal shield. Tube-on-panel is the basic configuration of KSTAR thermal shield.

An overview of KSTAR results

Nuclear Fusion, 2013
Since the first H-mode discharges in 2010, the duration of the H-mode state has been extended and a significantly wider operational window of plasma parameters has been attained. Using a second neutral beam (NB) source and improved tuning of equilibrium configuration with real-time plasma control, a stored energy of Wtot???450?kJ has been achieved with

In-vessel visible inspection system on KSTAR

Review of Scientific Instruments, 2008
To monitor the global formation of the initial plasma and damage to the internal structures of the vacuum vessel, an in-vessel visible inspection system has been installed and operated on the Korean superconducting tokamak advanced research (KSTAR) device. It consists of four inspection illuminators and two visible/H-alpha TV cameras.

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.

Development of a digital integrator for the KSTAR device

Review of Scientific Instruments, 2010
The development of an integrator for magnetic diagnostics becomes more important as the pulse length of fusion devices gets longer and longer, especially for present-day superconducting fusion devices. A small offset in the signal can cause a significant drift in the integrator output for long pulse experiments.
