'V I GE EIGHT THE MICHIGAN DAILY FRIDAY, OCTOBER 21, 1955 . ETTER DETECTION: Expect Satellite to Bring Cosmic Ray Information (Continued from Page 1) of high-energy secondary rays in- creases with altitude. Sometimes their character changes, too. Investigate Report The salt mine studies were made to investigate a report from Hun- gary's coal mines that a strong neutral secondary cosmic ray had been found that gained relative strength with depth. Studies inhthe salt mines here and at Cornell indicated this .was wrong, that the particles were the same kind as the most abundant at sea level. Prof. Hazen studies great air showers of secondary particles that reach the earth simultaneously. They are produced by very high- energy primary rays striking the earth's atmosphere. He makes es- timates *of the primaries' energy from the size of the shower. His studies are directed at an- swering two main questions about cosmic rays. How Great Is the Energy? First, how high does the energy of primary rays go? How big can an air shower get? Tfie greater the energy, the straighter the path they followin our galaxy. If the energy is great enough, the rays may escape the galaxy as starlight does instead of remaining in a circular path within stellar mag- netic fields. The second question concerns the origin of cosmic rays and its cosmological implications. Best guess, according to Prof. Hazen, for the origin of cosmic rays is collisions of stellar clouds and ato- mic nuclei. Under this theory of the late renowned atomic physicist Enrico Fermi, collisions have been work- ed out mathematically. After their production, which is seen as a sizeable power load on the gal- axies or the universe, the rays be- come trapped in their galaxies by magnetic fields. All these uncertainties about cos- mic rays, which Prof. Hazen stu- dies from high-energy secondaries on the earth's surface to low-en- ergy primaries in the upper at- mosphere, should become at least, partially cleared up if a satellite is successfully launched.
