Testing of the Wendelstein 7-x stellarator has started with a bang, albeit a very very small one, with researchers switching on the experimental fusion reactor to produce its first helium plasma ...

The first plasma in Wendelstein 7-X. It consisted of helium and reached a temperature of about one million degrees Celsius IPP The Wendelstein 7-X "Stellarator" at the Max Planck Institute for ...

Hydrogen Arguments. While helium is exceedingly light as compared with air, it is somewhat heavier than hydrogen. The total lift of a helium-filled dirigible is accordingly some 10% less than that ...

Having fired up the Wendelstein 7-X to produce helium plasma late last year, researchers have built on their early success to generate its first hydrogen plasma, an event they say begins the true ...

Far more common is hydrogen (92%) and helium (7%). The planet that dominates the solar system is Jupiter and its atmosphere is 90% hydrogen and 10% helium , with just traces of other elements.

How to fake super-heavy hydrogen In a feat of modern-day alchemy, atom tinkerers have fooled hydrogen atoms into accepting a helium atom as one of their own. The camouflaged atom behaves ...

Before the Federal Chancellor fired the first hydrogen plasma in Wendelstein 7-X, the researchers in Greifswald had started the fusion device on 10 December 2015 with an initial helium plasma. Since ...

“Not all, but some white dwarfs transition from being hydrogen- to helium-dominated on their surface,” Caiazzo explained. “We might have possibly caught one such white dwarf in the act.” ...

The primary plasma constituents are hydrogen and helium and their isotopes and the molecules and molecular ions may be in rovibrationally or electronically excited states. For a complete description ...
