BEIJING, Sept. 29 (Xinhua) -- The following are the highlights of China's key technology news from the past week: COSMIC RAYS An international research team has conducted a precise measurement of the spectrum of protons, the most abundant component of cosmic rays, in an energy range from 40...
X-rays and gamma-rays detected by these balloons are “secondary cosmic rays,” produced by the crash of primary cosmic rays into Earth’s upper atmosphere. They trace radiation percolating down toward our planet’s surface. The energy range of the sensors, 10 keV to 20 MeV, is similar to...
Tanaka’s new proposal is designed to defeat eavesdroppers by instead turning to a natural and ever-present resource of randomness: cosmic-ray muons. Cosmic rays, which are mainly protons, rain down on the Earth from deep space and generate showers of pions and other particles when they collide...
WASHINGTON, Sept. 21 (Xinhua) -- Scientists on Thursday confirmed that cosmic rays with the highest energies that bombard the Earth originated from outside our Milky Way galaxy. In a paper published in the journal Science, a group of more than 400 scientists from 18 nations, reported that th...

Chen said one popular hypothesis is that the high-energy neutrinos and gamma rays are potentially produced simultaneously when high-energy cosmic rays originate. "If we can detect the two particles together, we can determine the origin of the cosmic rays," said Chen. ...
