Imposing strikes at the South Pole: Science Ticker - daily news from Science and Technology
From space, lawn continually elementary particles from the group of neutrinos technika reviews to the earth - and usually go as if by magic through the planet through. Some of these particles come with considerable momentum served, initial results show an immense detector in the ice of Antarctica. Some of the registered neutrinos had therefore energies as they exceed the capabilities of current particle accelerators by several orders of magnitude.
"We have started to do it here with high-energy neutrinos, technika reviews which do not come from the atmosphere," says Francis technika reviews Halzen of the University of Wisconsin technika reviews in Madison, principal investigator of the project IceCube detector. Two of the registered since May 2010 neutrinos put in their collision with atoms in the ice-free energy of a little more than 1 peta-electron volts, determined the physicist and his colleagues. In a further 26 events there were over 30 Tera electron volts, which is still more than twice as much as last in the LHC particle accelerator near Geneva. technika reviews "This is exactly what we were looking technika reviews for," adds Halzen.
Neutrinos are nearly massless elementary particles, resulting in nuclear reactions, such as radioactive decay, but also in the ongoing nuclear fusion in the interior of stars and in supernova explosions. The particles interact with matter so rare that their evidence within an acceptable time large detector masses are needed. In the case of the detector IceCube, attended by German researchers are involved, there is a cubic kilometer of ice, which is peppered with 5,160 sensitive optical sensors. These sensors detect the faint blue glow that cause the products of the rare neutrino strikes in the ice.
The properties of the registered high energy neutrinos are not explainable by nuclear technika reviews reactions in the atmosphere, emphasizes Halzens colleague Nathan Whitehorn. Conversely, they correspond almost exactly to the expectations of neutrinos as they should technika reviews be sent in cosmic ray bursts or in the formation of black holes. Since neutrinos unaffected by rushing from gravity and magnetic fields, the universe, they could provide valuable information about such events.
The atmosphere in the text is probably a typo, right?
Hello, Mr. Kieser. Thank you for your comment! Reproduced in the 2nd paragraph statement is a direct quote from Francis technika reviews Halzen. In fact, the cosmic radiation causes a variety of nuclear reactions in the atmosphere (see Fig. Http://de.wikipedia.org/wiki/H%C3%B6henstrahlung#Wechselwirkung_mit_der_Erdatmosph.C3.A4re). Such reactions we owe not only the C14 dating method, but in the form of muons also a testament to the relativistic time dilation. Atmospheric nuclear fusion technika reviews is nowhere mentioned. :-)
It is in the discovery of the Lord Halzen does not describe to neutrinos technika reviews general, but those with extremely high energy like we have not even measured from a supernova, correct?
