Researchers in China have used a novel approach to explain the presence of supra-thermal ions in nuclear fusion reactions.

For some background, plasma is the fourth state of matter, often created by heating a neutral gas or ionizing the gas in a strong electromagnetic field. The availability of free electrons allows ...

[Whoopjohn] decided to build a driver board for a display he pulled from a pinball machine. You’ve probably seen these used to scroll both score and messages using a total of sixteen 15-segment ...

An efficient way to ionize the gas for MHD acceleration is through electron beam ionization where high-energy electrons are injected directly into the flow. Plasma Fueled Engines (PFE) offer a means ...

A company aims to bring a nuclear fusion plant online in the early 2030s, but the path to this breakthrough is anything but ...

Halved grapes boost magnetic fields, paving way for alternative microwave resonators for quantum sensing devices.

Magnetic confinement fusion reactors aim to extract fusion energy by confining extremely hot plasma in strong magnetic fields. Scientists have used a pair of lasers and a supersonic sheet of gas ...

Plasma welding machines melt areas with an arc and then use a high-velocity, high-temperature ionized gas to make welds. The process of plasma welding is used to bring better control to the arc ...

The purpose of this communication is to discuss another possibility, namely, to insulate the plasma from the walls by means of a magnetized gas at high pressure. As the thermal conductivity ...

For example, a plume expanding into ambient gas of low pressure around 100 mTorr exhibits plume splitting and sharpening [1]. A definitive mechanistic explanation for laser-induced plasma plume ...

Researchers from Lawrence Berkeley National Laboratory have accelerated electrons to high energies in less than a foot using ...
