...detect the existence of the anti-deuteron, Dr. Leon M. Lederman and his group worked with a device called a mass spectrometer at Brookhaven National Laboratory on Long Island. Using Brookhaven's 33 billion electron volt synchrotron, they bombarded a target of beryllium with a beam of high-energy protons. This resulted in a debris of. particles that sped through the 300-ft. magnetic field of the spectrometer, where they could be sorted and analyzed. When 16 giant, 20-ton magnets were set to pass positively charged particles, the apparatus made careful readings of the flight path, momentum...
...alloy, the fuel is mixed with zirconium hydride, which acts as a moderator, slowing down the high-energy neutrons released by fissioning atoms of U 235. The heat of the reactor is carried away by a sodium-potassium alloy (NaK) that turns to liquid at 48°F. A beryllium reflector 2½ in. thick bounces escaping neutrons back into the uranium and keeps the reactor operating. When four openings in the reflector are uncovered, neutrons leak away, slowing or stopping the nuclear reaction...
...clot, but with a clot the problem is how to make it and how to keep it from traveling and causing still more brain damage. Dr. Mullan and fellow workers noted that not only does electricity promote clotting, but also, unaccountably, so does a piece of copper, cadmium or beryllium, even without an electric current to help the process...
...marginal exception: beryllium 7, with a decay rate that changes by at most 0.1% when its atoms are built into certain chemical compounds...
Adams' crust piercer, which he patented and assigned to the AEC, is a high-temperature nuclear reactor designed to melt its way into rock. The reactor is 2 ft. to 3 ft. in diameter, and its active material (uranium oxide) is enclosed in a cylinder of beryllium oxide, which serves as a heat insulator. The lower point, mostly tungsten, is heavy, while the upper point, mostly beryllium, is light...
