Space Turbulence Measured In The Lab
2012-12-18 05:47:51

[ Watch the Video: Measuring Space Tubulence ] April Flowers for redOrbit.com - Your Universe Online We all know that turbulence exists on Earth, but does it really exist in outer space? And if it does, how would you prove it? A research team from University of Iowa (UI) and the University of California, Los Angeles reports that they have directly measured space wind for the first time in a laboratory. “Turbulence is not restricted to environments here on Earth, but also...

New Results Pave Way For Future Of X-ray Astrophysics Research
2012-12-13 17:36:02

Lee Rannals for redOrbit.com — Your Universe Online Scientists are paving the way for future X-ray astrophysics research by explaining why observations from orbiting X-ray telescopes do not match theoretical predictions. The team used powerful X-rays from the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory to study and measure a key process at work in extreme plasmas like those found in stars, black holes and...

Editors from CEAG's Plasma TV Buying Guide have completed new size lists that cover the 42 inch, 50 inch, and 60 inch size plasma TVs. Atlanta, Georgia (PRWEB) December 11, 2012 Expert Reviewers and Editors from CEAG's TV Buying Guides have written complete size list for plasma TVs over 42 inches. The sizes covered were 42 inch, 50 inch, and 60 inch. The Panasonic TC-P42UT50 topped the Best 42 inch Plasma list. Jack Burden did the review on this one. He said, “The TC-P42UT50 does have...

Graphite Experiment Leads To Unexpected Results
2012-11-29 06:26:14

Lee Rannals for redOrbit.com - Your Universe Online Scientists from the University of Warwick and Oxford University have come up with unexpected results in an experiment with strongly heated graphite, posing a new problem for physicists working in laser-driven nuclear fusion. The research may lead astrophysicists to revise the understanding of the life cycle of giant planets and stars. The team was attempting to gain a better understanding about how energy is shared between the...

Significant progress made in evaluating the density of active species used in medical applications of plasma physics could improve the accuracy of treatment An international team of scientists working at the Plasma Technology research unit at Ghent University, Belgium, has determined for the first time the absolute density of active substances called radicals found in a state of matter known as plasma, in a study about to be published in EPJ D. These findings could have important...

Studies by Berkeley Lab scientists of electron beam quality in laser plasma accelerators include novel tests for slice-energy spread Part Two: Slicing through the electron beam Wim Leemans of Berkeley Lab´s Accelerator and Fusion Research Division heads LOASIS, the Laser and Optical Accelerator Systems Integrated Studies, an oasis indeed for students pursuing graduate studies in laser plasma acceleration (LPA). Among the most promising applications of future table-top accelerators...

Table Top Accelerators To State Of The Art Beams
2012-10-22 15:34:11

Berkeley Lab´s lead in laser plasma acceleration research continues with new benchmarks for electron beam quality Part One: Focusing in on beam focus The rapidly evolving technology of laser plasma accelerators (LPAs) — called “table-top accelerators” because their length can be measured in centimeters instead of kilometers — promises a new breed of machines, far less expensive and with far less impact on the land and the environment than today´s...

Scientists Explain The Sound In Saturn’s Rings
2012-10-17 19:24:53

Alan McStravick for redOrbit.com — Your Universe Online The theoretical prediction of the existence of linear and nonlinear dust acoustic waves in dusty plasmas was first postulated more than two decades ago by Professor Padma Kant Shukla. Since that early prediction, these acoustic waves have been observed in several laboratory experiments. With that discovery, Professor Shukla´s discovery has transformed the field of plasma physics, even opening up a new interdisciplinary...

Mug Handles May Help Hot Plasma Give Cheaper, Controllable Fusion Energy
2012-10-12 09:28:09

Researchers around the world are working on an efficient, reliable way to contain the plasma used in fusion reactors, potentially bringing down the cost of this promising but technically elusive energy source. A new finding from the University of Washington could help contain and stabilize the plasma using as little as 1 percent of the energy required by current methods. “All of a sudden the current energy goes from being almost too much to almost negligible,” said lead author...

Hannes Olof Gösta Alfvén (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in Norrköping, Sweden. Alfvén received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves." He was originally trained as an electrical power engineer and later moved on to research and teaching in the fields of plasma physics. Alfvén made many contributions to plasma physics, including theories describing the...

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...

Solar Prominence -- Solar prominences are large arch-shaped structures observable in the solar corona. These often have a twist and occasionally become unstable, ejecting plasma and magnetic flux out from the sun. The physics of solar prominence instability is believed to be governed by magnetic forces and magnetic helicity issues. It is thought that instability occurs when a magnetic flux tube becomes excessively twisted. ----- Click here to learn more on this topic from eLibrary:
