Sentences with phrase «magnetic confinement»
"Magnetic confinement" refers to a method used to trap and control charged particles, like those found in a plasma, using magnetic fields. It keeps the particles contained within a specific region to prevent them from escaping or interacting with the surrounding environment. Full definition
After that I wanted to do something very practical so I switched to work on magnetic confinement fusion, as part of the ongoing effort to develop fusion reactors.

The collaboration will study fusion in a relatively unexplored intermediate density regime between the lower - than - air density of magnetic confinement fusion (MCF) that is studied at the ITER project in southern France, and the greater - than - solid density of laser - driven inertial confinement fusion (ICF) at the National Ignition Facility at Lawrence Livermore National Laboratory.
The scientists involved hope to obtain magnetic confinement for 30 minutes (compared with up to 30 seconds for tokamaks) in the next few years, making it a relatively steady - state system.
Most fusion research focuses on magnetic confinement, using powerful electromagnets to contain a thin plasma of hydrogen isotopes and heat it until the nuclei fuse.
(ITER uses a different approach, called magnetic confinement fusion.)
The breakthrough is in magnetic confinement fusion, in which hydrogen is heated until it is a plasma 10 times hotter than the centre of the sun, and held in place by strong magnetic fields until fusion reactions occur.
«To be more precise, it is «differential magnetic confinement» in that some species are confined while others are lost quickly, which is what makes it a high - throughput mass filter.»
This research was funded by the DOE Office of Science together with the National Key Research and Development Program of China, the National Nature Science Foundation of China, and the National Magnetic Confinement Fusion Science Program of China.
He headed the Tokamak Fusion Test Reactor, then the largest magnetic confinement fusion facility in the U.S., from 1991 to 1997.
The stronger magnetic field makes it possible to produce the required magnetic confinement of the superhot plasma — that is, the working material of a fusion reaction — but in a much smaller device than those previously envisioned.
Two major fusion research reactors are being built over the next decade — the international ITER magnetic confinement reactor (for $ 5 to 10 billion) and the US National Ignition Facility (NIF — $ 2 to 5 billion) to study «inertial confinement».
Recent results with Tokamak experiments provide insights into the problem of magnetic confinement.
In the United States, government - funded labs are simultaneously pushing two tracks — inertial fusion and magnetic confinement fusion — but neither with the vigor needed to advance the field meaningfully, according to scientists.
The two leading techniques have been inertial confinement and magnetic confinement, involving huge magnetic fields to contain a plasma in a doughnut - shaped machine called a tokamak.
But turbulence frequently causes heat to leak from its magnetic confinement.
The other main alternative is magnetic confinement.
He said that their magnetic confinement concept combined elements from several earlier approaches.
«The interesting thing about our ideas on mass separation is that it is a form of magnetic confinement, so it fits well within the Laboratory's culture,» said physicist Nat Fisch, co-author of the paper and director of the Princeton University Program in Plasma Physics.
The Group comprises 10 academic staff with expertise in the following areas: high energy density plasmas; inertial confinement fusion; MHD plasma modelling; fundamental plasma processes such as reconnection, turbulence and shocks; laser - plasma interactions including particle acceleration; experimental laboratory astrophysics, and magnetic confinement fusion.
Magnetic: A magnetic confinement system has a donut - shaped chamber containing a ring of ionized gas (the plasma) that carries a huge circulating electric current confined to the donut by very large magnetic fields.
There are two approaches to fusion energy, inertial confinement (the National Ignition Facility or NIF at Lawrence Livermore National Lab, for example) and magnetic confinement (the International Thermonuclear Experimental Reactor or ITER, for example).
