Latest equipment tracking cosmic rays reveal the mystery of its origins.

<P> According Technology Channel [http://tech.] 2008 年 1 月 4 reported: Scientists created a ground equipment, and the cosmic ray particles through the blue flash, followed by a comprehensive understanding of galaxies, revealing cosmic ray particles .The energy of the mystery. .</ P> <P> cosmic ray simulation graph </ P> <P> </ P> <P> HESS telescope array </ P> <P> According to the U.S. space news report, scientists at the University of Chicago developed a .advanced sensor equipment can detect particles in cosmic rays and the blue flash, is expected to hit Earth's atmosphere soon reveal violent mystery of the origin of cosmic rays. .The construction cost is even less than the balloons and satellites. .</ P> <P> before that cosmic rays come from near the center of the galaxy or a supernova, will help astronomers understand better their origin to the universe to draw more precise figure. .University of Chicago physicist Scott Wentworth Klee said: "galactic cosmic rays is not in the audience, and in galactic dynamics play an important role. As a comprehensive understanding of galaxies, we have to understand the cosmic rays." </ P> .<P> However, scientists usually by ground or space instruments to understand the cosmic rays. .Balloons and satellites used to detect the first blue flash, that we know of Cerenkov radiation - this is when cosmic rays hit Earth's upper atmosphere and violent release of energy, issued a blue flash. .After cosmic ray burst open, and the second issue of the blue flash. .Ground sensors usually only detect the second flash. .</ P> <P> bombarded day tens of thousands of small particles in the large parking area, but the rare high-energy particle bombardment in the year, with a few areas. .As the satellite and balloon ascend into the air, more suitable for the detection work, but they can only cover a small area. .Walkley, said: "a 400 million U.S. dollars a year can only be found in a satellite secondary particles, but we want to find tens of thousands of times. We always want to adopt a new way to do this." </ P> < .P> Walkley and colleagues created a ground equipment, capable of detecting the first and second flash. .The instrument resolution and stronger power than the existing surface detectors of about 10 times. .Scientists, the blue flash through the use of this information to identify the secondary particles is what elements, sources are. .For example, some particles will be more likely to come from the violent eruption of a supernova. ."</ P> <P> no one thought of the ground equipment to detect the first flash, until the Walkley made this statement in 2001, did not realize this is a good idea. Namibia, scientists have confirmed this idea can be applied to .HESS telescope array called. composed of HESS telescope system covers an area of 107 square meters, are installed every 960 on the high sensitivity of the sensor. After the Walkley VERITAS telescope array by name to build his own observatory .. The aim is to join forces with air sensors for high-precision detection of large areas. </ P> <P> This instrument can also help improve the cosmic ray particles of energy reveal the mystery. energetic particles is much more than the low-energy particles to be scarce, but .is always still there. Some researchers say cosmic rays produced supernova energy particles may be a sudden outbreak. However, it remains to be further confirmed by scientists. </ P> </ p>.
