A new experiment that reproduces the magnetic fields of the Earth and other planets has yielded its first significant results. The findings confirm that its unique approach has some potential to be developed as a new way of creating a power-producing plant based on nuclear fusion "” the process that generates the sun's prodigious output of energy. Fusion has been a cherished goal of physicists and energy researchers for more than 50 years. That's because it offers the possibility of...

A new prototype device that can rid hands, feet, or even underarms of bacteria, including the hospital superbug MRSA, has been developed and is in the testing stage, BBC News reported. The device creates what is called a plasma, which produces a cocktail of chemicals in air that kill bacteria but are harmless to skin. Experts say a related approach could see the use of plasmas to speed the healing of wounds. These so-called plasmas could help solve gum disease or even body odor, according to...

Experiments in RFP fusion device show higher currents lead to self-organized helical plasma If you keep twisting a straight elastic string, at some moment it starts kinking in a wild way. Something similar occurs when one increases the electrical current flowing in a magnetized plasma doughnut: it takes on a wild helical shape, which spoils its performance. This phenomenon concerns scientists exploring fusion power, who use powerful magnetic fields to confine plasma during their experiments....

Progress in advanced operational scenarios for tokamak fusion devices provides hope for steady-state fusion power plants In the quest to produce nuclear fusion energy, researchers from the DIII-D National Fusion Facility have recently confirmed long-standing theoretical predictions that performance, efficiency and reliability are simultaneously obtained in tokamaks, the leading magnetic confinement fusion device, operating at their performance limits. Experiments designed to test these...

Just as health-food manufacturers work on developing the best possible sodium substitutes for low-salt diets, physicists at the National Institute of Standards and Technology (NIST) have acquired new knowledge on a promising sodium alternative of their own. Sodium-like tungsten ions could pepper"”and conveniently monitor"”the hot plasma soup inside fusion energy devices, potential sources of abundant, clean power. Tungsten"”having the highest melting point of any...

A University of Nevada-Reno scientist has received a U.S. Department of Energy grant to study high-energy plasma's role in astrophysics and other fields. Professor Roberto Mancini, chairman of the school's physics department, said the $690,000 grant will further his studies into ultra-high temperature and non-equilibrium plasmas, researching what happens to matter around black holes. Mancini will conduct some of his experiments with the pulsed-power machine at the Sandia National Laboratories...

Experiment to shed light on high-energy plasma's role in astrophysics, energy production and X-rays Using one of the greatest sources of radiation energy created by man, University of Nevada, Reno researcher and faculty member Roberto Mancini is studying ultra-high temperature and non-equilibrium plasmas to mimic what happens to matter in accretion disks around black holes. Physics department professor and chair Mancini has received a $690,000 grant from the U.S. Department of Energy to...

Researchers are adapting the same methods used in fusion-energy research to create extremely thin plasma beams for a new class of "nanolithography" required to make future computer chips.Current technology uses ultraviolet light to create the fine features in computer chips in a process called photolithography, which involves projecting the image of a mask onto a light-sensitive material, then chemically etching the resulting pattern.New nanolithography will be needed to continue advances in...

On Friday, a U.S. weapons lab unveiled a super laser with the power to burn as hot as a star. The National Ignition Facility's main purpose for the tool is to gauge the reliability and safety of the U.S. nuclear-weapons arsenal, but scientists say it could deliver breakthroughs in safe fusion power. "We have invented the world's largest laser system," actor-turned-governor Arnold Schwarzenegger said during a dedication ceremony attended by thousands including state and national officials. "We...

California Gov. Arnold Schwarzenegger Friday dedicated the world's largest laser system in Livermore, calling it a gateway to new energy sources. The sprawling National Ignition Facility at the Lawrence Livermore National Laboratory east of San Francisco has been 12 years in the making and is designed to further research into fusion energy. NIF has the potential to revolutionize our energy system -- teaching us a new way to harness the energy of the sun to power our cars and homes,...

Igor Yevgenyevich Tamm born in Vladivostok, Russia on July 8, 1895 was a Soviet physicist and mathematician. He studied at the University of Edinburgh in 1913-1914. He then switched to Moscow State University where he graduated in 1918. He developed an approximation method for many-body physics, in 1945. He worked with Andrei Dmitrievich Sakharov to create a tomohak system based on a toroidal magnetic thermonuclear reactor, in 1958. This led to the T-3 Soviet magnetic confinement...
