That is not to say that the U.S. is second rate. The Tevatron, an accelerator at Fermilab, near Chicago, that smashes together protons and antiprotons, is still the most powerful collider in the world, and the proposed superconducting supercollider, planned for Texas, will be more powerful still. Proton-antiproton collisions entail more energy than electron- positron collisions and thus are more likely to generate previously undiscovered particles. But proton-antiproton impacts generate more subatomic debris, which makes it harder to study the properties of individual particles carefully. For what Amaldi calls "precision physics," Europe could soon...
...make these extremely concentrated energy bursts by using its magnets to guide protons, moving at nearly 186,000 miles per second, around the enormous ring in opposite directions. Then they would be forced to collide. The major difference between the SSC and the largest accelerator that currently exists -- the Tevatron, at Fermilab near Chicago -- is size and, therefore, power. The SSC would produce some 20 times as much energy as the Tevatron can and would generate correspondingly more interesting particles. Among the discoveries are certain to be some surprises. Says Harvard physicist Roy Schwitters, who is a leading candidate...
Should SSC designers move ahead with plans to use conventional, low- temperature superconducting magnets, known quantities that are already in place and operating at Fermilab's Tevatron accelerator in Batavia, Ill.? Or should they hold off indefinitely, awaiting development of the new high- temperature superconducting variety, which may someday be able to generate even stronger magnetic fields at less cost...
...example, giant particle accelerators require extremely powerful magnets to keep the particles confined to a circular track as they move at nearly the speed of light. At Fermilab, near Chicago, the world's most powerful accelerator, known as Tevatron, uses more than 1,000 superconducting magnets cooled with liquid helium at a cost of $5 million a year. But the efficiency of the magnets saves Fermilab an estimated $185 million annually in electric energy costs. The superconducting super collider, a mammoth accelerator 52 miles in circumference, endorsed last month by President Reagan for completion in the 1990s at a projected...
...Tevatron should help right the transatlantic balance. Like Fermilab's existing accelerator, in whose tunnel it was built, the new machine is a giant four-mile-long circular particle race track, capable of whipping protons to within a shade of 186,000 miles per sec., the speed of light. When these high-velocity particles strike a target, for example, a metal bar, they shatter its component atoms, resulting in a burst of subatomic debris. Some of these particles are so ephemeral that they survive for only minute fractions of a second; from the trail they leave in detection devices...
