Until George Strock photographed the cyclorama at Gettysburg for TIME (see ART), no one had ever before made a continuous still photograph of this circular panorama...
...rises as he is supposed to, the pilot would then reset the exhaust controls for normal jet flight. He could fly in any direction by choosing the appropriate set of burners in his circular power plant. So that he would always be facing forward, the cockpit would rotate automatically as the craft changed direction...
...Charter Hill above Berkeley, Calif, a strange and monstrous machine, the AEC's bevatron,* was slowly coming to life last week. Housed in a circular building 75 feet high is a steel doughnut 135 feet in diameter and weighing 10,000 tons. This is the world's greatest magnet, energized by current flowing through 26.5 miles of copper cable two inches thick. When its current was first turned on, a crashing clatter shook the bevatron building as iron objects on the floor rearranged themselves violently to fit the invisible pattern of its magnetic field...
...around inside it, a dangerous, man-made genie throbs and thrashes. Out of an electric arc springs a swarm of protons (hydrogen nuclei). Powerful forces grab them and speed them down a channel toward the great machine. They sail into the chamber, and the magnet steers them in a circular orbit...
...cosmotron, a "doughnut" 70 ft. in diameter and 8 ft. in cross section, needs 2,000 tons of steel for the magnets that keep its protons on circular orbits. To build a 25 bev machine on this same pattern would have required a fantastic amount of steel. Chief difficulty: the particles cannot be kept on accurate orbits, and so they must be provided with a wide (32 in. cross section) vacuum chamber. It takes massive steel magnets to fill this space with the necessary magnetic field...
