Posted:This is quite wow

Written by: www.livescience.com

Scientists have produced superheated gas exceeding temperatures of 2 billion degrees Kelvin, or 3.6 billion degrees Fahrenheit.

This is hotter than the interior of our Sun, which is about 15 million degrees Kelvin, and also hotter than any previous temperature ever achieved on Earth, they say.

They don't know how they did it.

The feat was accomplished in the Z machine at Sandia National Laboratories.

"At first, we were disbelieving," said project leader Chris Deeney. "We repeated the experiment many times to make sure we had a true result."

Thermonuclear explosions are estimated to reach only tens to hundreds of millions of degrees Kelvin; other nuclear fusion experiments have achieved temperatures of about 500 million degrees Kelvin, said a spokesperson at the lab.

The achievement was detailed in the Feb. 24 issue of the journal Physical Review Letters.

The Z machine is the largest X-ray generator in the world. Its designed to test materials under extreme temperatures and pressures. It works by releasing 20 million amps of electricity into a vertical array of very fine tungsten wires. The wires dissolve into a cloud of charged particles, a superheated gas called plasma.

A very strong magnetic field compresses the plasma into the thickness of a pencil lead. This causes the plasma to release energy in the form of X-rays, but the X-rays are usually only several million degrees.

Sandia researchers still arent sure how the machine achieved the new record. Part of it is probably due to the replacement of the tungsten steel wires with slightly thicker steel wires, which allow the plasma ions to travel faster and thus achieve higher temperatures.

One thing that puzzles scientists is that the high temperature was achieved after the plasmas ions should have been losing energy and cooling. Also, when the high temperature was achieved, the Z machine was releasing more energy than was originally put in, something that usually occurs only in nuclear reactions.

Sandia consultant Malcolm Haines theorizes that some unknown energy source is involved, which is providing the machine with an extra jolt of energy just as the plasma ions are beginning to slow down.

Sandia National Laboratories is located by Albuquerque New Mexico and is part of the U.S. Department of Energy (DOE).



eek

z machines, unknown power sources... This is clearly the sexiest thing in science since giant robots.

What? Electricity? We've had the hang of that for a while y'know...

This is Nuclear Fusion, eg. the power of the sun.

~ 2,2 million volts is in a lightning bolt (due to a lack of physical education I have no clue how amperes relate to volts and maybe I'm just talking rubbish)... however it (naturally) generates temperatures of 30.000 degrees celsius... eek

Errm Doc, how many volts does your bolt hold? umm wink

Posted:30,000 degrees celsius eh? Thats a lot.
however this experiment produced a temperature which was 500 times hotter than that.

Lightning strikes generally have a peak current of around 10,000A, although currents of over 200,000A have been reported.

This experiment used a peak current of around 20,000,000A, which is 2000 times more than a typical lightning strike, and 100 times more than the most powerful strikes reported.

So this experiment is significantly more sexy than lightning.

Posted:So... Simian.

What about this discovery turned you on? I mean my reaction (and remember, I'm a trained scientist with a graduate degree) is...

"oh. neat."

And yet yours was obviously "OMFG, THAT ROXXORZ TEH B1G 111111!" (or something in that general genre of geeky ecstasy).

So...

Why?
