Sentences with phrase «use magnetic fusion»

The International Thermonuclear Experimental Reactor program in the south of France will use magnetic fusion and employ strong magnetic fields to hold and fuse hydrogen plasma.

Not exact matches

Also backed by the United States, Russia, China and Japan, ITER is the largest of the various fusion experiments underway and proposes to trigger fusion using a super-conducting magnetic compression process.

In research machines such as fusion reactors, scientists use strong magnetic fields to confine plasma, but those fields interfere with seeing what might happen during a natural dynamo.

Targeted biopsy using new fusion technology that combines magnetic resonance imaging (MRI) with ultrasound is more effective than standard biopsy in detecting high - risk prostate cancer, according to a large - scale study published today in JAMA.

In a recent paper published in EPJ H, Fritz Wagner from the Max Planck Institute for Plasma Physics in Germany, gives a historical perspective outlining how our gradual understanding of improved confinement regimes for what are referred to as toroidal fusion plasmas — confined in a donut shape using strong magnetic fields — have developed since the 1980s.

But if we do away with solid vessels and use magnetic fields (such as in fusion reactors) instead, then higher temperatures can be reached.

It is an experimental fusion machine based on the «tokamak» concept — a toroidal (doughnut - shaped) magnetic configuration that is used to create and maintain the conditions for controlled fusion reactions.

Inertial confinement fusion (ICF) seeks to create those conditions by taking a tiny capsule of fusion fuel (typically a mixture of the hydrogen isotopes deuterium and tritium) and crushing it at high speed using some form of «driver,» such as lasers, particle beams, or magnetic pulses.

Since the operating temperature for fusion is in the hundreds of millions degrees Celsius, hotter than any known material can withstand, engineers found they could contain a plasma — a neutral electrically conductive, high - energy state of matter — at these temperatures using magnetic fields.

(ITER uses a different approach, called magnetic confinement fusion.)

Despite proposed cuts to the U.S. magnetic fusion program, a new report advocates a parallel effort to pursue fusion energy using the rival inertial confinement scheme.

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.

In fact, some of the more promising technologies involved with nuclear fusion research use magnetic fields to contain plasmas.

American researchers have shown that prospective magnetic fusion power systems would pose a much lower risk of being used for the production of weapon — usable materials than nuclear fission reactors and their associated fuel cycle.

PPPL has used such diagnostic systems, called X-ray crystal spectrometers, for decades to study the data from the laboratory's magnetic fusion research.

New research suggests scientists are getting close to using magnetic fields and powerful particle beams to control fusion reactions.

Creating the new spectrometer are physicists Kenneth Hill and Manfred Bitter, whose diagnostic designs are used in magnetic fusion experiments around the world.

The concept uses a laser to heat fusion fuel contained in a small cylinder as it is compressed by the huge magnetic field of Sandia's massive Z accelerator.

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.

Stellarators are fusion devices that use twisting, potato chip - shaped magnetic coils to confine the plasma that fuels fusion reactions in a three - dimensional and steady - state magnetic field.

Originally proposed in a 2010 Sandia theoretical paper, the concept uses a laser to heat fusion fuel contained in a small cylinder (called a liner) as it is compressed by the huge magnetic field of Sandia's massive Z accelerator.

Stellarators are fusion facilities that confine plasma in twisty magnetic fields, compared with the symmetrical fields that tokamaks use.

A tokamak, the most advanced magnetic fusion concept, uses magnetic fields in a donut - shaped ring to confine, heat, and squeeze plasma until it ignites, and then holds the burning plasma in place.

The plasmas in NSTX are, like most fusion experiments, confined using magnetic fields and walls designed to withstand the heat from plasmas with temperatures that exceed 100 million degrees Centigrade.

Unlike inertial systems, magnetic systems have reached the temperature necessary for fusion, but only through external heating devices that themselves use so much energy that you get no net energy out while they are on.
