Reference 1-GWe D-T reactors; tokamak TR-1, spherical tokamak ST-1 and helical HR-1 reactors, are designed using PEC (Physics Engineering Cost) code, and thier plasma behaviors with Internal Transport Barrier (ITB) operations are analyzed using TOTAL (Toroidal Transport Analysis Linkage) code, which clarifies the requirement of deep penetration of pellet fueling to realize steady-state advanced...

The Tokamak Physics Experiment (TPX) was a steady-state, tokamak to be built at the Princeton Plasma Physics Laboratory. It would have been the first tokamak in the world with an entirely superconducting magnet system. The project was terminated by the United States Congress in 1995. However, most of the TPX mission has been adopted recently by the South Korean project KSTAR (Korean Superconduc...

A new reduced size ITER-RC superconducting tokamak concept is proposed with the goals of studying burn physics either in an inductively driven standard tokamak (ST) mode of operation, or in a quasi-steady state advanced tokamak (AT) mode sustained by non-inductive means. This is achieved by reducing the radiation shield thickness protecting the superconducting magnet by 0.5 m relative to ITER a...

In this research we investigated the effects of toroidal field ripple of tokamak on the plasma internal inductance. For this purpose, array of magnetic probes and also a diamagnetic loop with its compensation coil were designed, constructed, and installed on outer surface of the IR-T1 tokamak. Amplitude of the TF ripple is obtained 0.01, and also the effect of the TF ripple on the plasma intern...

Nonlinear electromagnetic stabilization by suprathermal pressure gradients found in specific regimes is shown to be a key factor in reducing tokamak microturbulence, augmenting significantly the thermal pressure electromagnetic stabilization. Based on nonlinear gyrokinetic simulations investigating a set of ion heat transport experiments on the JET tokamak, described by Mantica et al. [Phys. Re...

The unique flexibility of TCV in plasma shaping has been exploited to address different aspects of tokamak physics, for which the plasma shape may play a role. This paper summarizes the experiments undertaken in the TCV tokamak ("Tokamak à Configuration Variable") over the last decade essentially in stability and transport. This paper enables a comprehensive and integrated view of the various s...

As everyone known the significant progresses have been achieved on tokamaks, which means that the scientific feasibility of tokamak reactor for fusion energy has been achieved (Q=1). But for commercial power plan the economics will be very important. Therefore to find improved (advanced) confinement operation model is the popular topic always for tokamak research. On other hand if any tokamak o...

A kinetic simulation code based on the gyrokinetic ion dynamics in global general metric (including a tokamak with circular or noncircular cross–section) has been developed. This gyrokinetic simulation is capable of examining the global and semi–global driftwave structures and their associated transport in a tokamak plasma. We investigate the property of the ion temperature gradient (ITG) or ηi...

The various software systems developed for the DIII–D tokamak have played a highly visible and important role in tokamak operations and fusion research. Because of the heavy reliance on in-house developed software encompassing all aspects of operating the tokamak, much attention has been given to the careful design, development and maintenance of these software systems. Software systems respons...
