«Scientists perform first basic physics simulation of spontaneous transition of the edge of fusion plasma to crucial high - confinement mode.»

In 1982, German researchers discovered that the edge of the plasma can spontaneously bifurcate into a high pedestal with a steep gradient, or transport barrier, that produces the H - mode confinement and maintains the heat of the plasma core.

Twelve scientific divisions are investigating confinement of high - temperature hydrogen plasmas in magnetic fields, heating of plasmas, plasma diagnostics, magnetic field technology, data acquisition and processing, plasma theory, materials research, plasma - wall interaction, and systems studies.

On the other hand, in magnetic field confinement fusion plasma intended for a fusion reactor, which research is being conducted at the National Institute for Fusion Science, development of high precision electron density measurements is becoming an important research topic.

These promising new directions include higher fusion power densities, and hence smaller reactors; development of «transport barriers» in the plasma, leading to improved energy confinement and smaller sizes; self - driven plasma currents that permit steady - state operation and low recirculating power; and the development of advanced divertor concepts to provide particle control and heat removal over long reactor lifetimes.

ELMs develop regularly when the plasma enters a high - energy state known as high - confinement mode, or H - mode, which holds heat within the plasma more efficiently.

The campaign will also increase the heating power of the stellarator to eight megawatts to enable operation at a higher beta — the ratio of plasma pressure to the magnetic field pressure, a key factor for plasma confinement.

A main goal of tokamak research is to use magnetic plasma confinement to develop the means of operating high - pressure fusion plasmas near stability and controllability boundaries while avoiding the occurrence of transient events that can degrade performance or terminate the plasma discharge.
