...with asteroids increases, thinks Kohler, space voyagers may hitchhike on them, finding shelter from radiation, and perhaps fuel or structural material. Even a small asteroid will provide a steady base for telescopes. If an asteroid is traveling roughly parallel to the earth, it might be steered into an earth orbit. Then it could be hollowed out and used by spacemen as a roomy, steady, well-shielded satellite base...
...C.E.A. is actually two accelerating devices--a linear accelerator, which feeds electrons into the rings, and the circular "race track" itself. After injection, the electrons whirl around the circular orbit through a slender evacuated stainless-steel tube, The tube lies sandwiched between the jaws of 48 C-shaped magnets, each 12 feet long and weighing six tons. These magnets provide the transverse force which keeps the electrons in a circular path...
...bunches of 100 million at the rate of 60 bunches per second. At 16 places in the ring, there are radio-frequency powered acceleration cavities. Each time the electron bunch passes through a cavity, its energy increases. The electron pulses thus receive discrete "kicks" of energy as they orbit, until they have finally reached the energy level desired for any particular experiment. The machine is capable of pushing electrons up to an energy of six billion electron volts. At that energy level, the electrons are travelling at 99.999,9996 per cent of the speed of light, and their mass...
This accelerator will overcome the most serious objection to a circular machine: the tremendous quantity of energy that is radiated as the electron revolves around the track. For a fixed orbit radius, the radiation losses increase with the fourth power of the particle energy. Eventually, the point is reached where most of the accelerating energy is lost immediately as radiation...
...immediate result of the flight was the probable cancellation of a second six-orbit jaunt. The next U.S. astronaut will probably fly 18 orbits early in 1963, staying in space for a full day. This will leave the U.S. still behind the Russians, whose heavier and better provisioned spacecraft have stayed in space for three and four days, but Astronaut Schirra-who is being called by admirers "the first real space pilot''-made a giant step toward catching...
