LONGEST ROAD TUNNEL in world will be carved through Mont Blanc in the Alps, will run seven miles between Italy and France, cut road distance from Paris to Milan by 194 miles. Cost: $31.6 million...
Steam Steering. Operation at such dizzy height and speed has posed special problems and produced oddities in design. X-15's large vertical stabilizers are wedge-shaped, as if their trailing portions had been cut off with a saw. Wind-tunnel tests have shown that such a wedge is more efficient than a conventional streamlined shape for keeping the X-15 aligned on course as the atmosphere thins out at high altitude...
...Cambridge Electron Accelerator, a joint undertaking of MIT and Harvard, was begun in April 1956 and is now about half completed. A two-story administration and laboratory building has been in use for the past six months, and the huge circular tunnel that comprises the accelerator itself is nearly ready. Still to come are a powerhouse and an experimental building which will house the various instruments of measurement...
Since the accelerator is a unique machine, says M. Stanley Livingston, professor of physics at MIT and director of the project, the design of both the tunnel and the measuring apparatus requires a good deal of original work. To this end, physicists and engineers from MIT and Harvard have been busy for the past two years. Livingston expects construction to be finished early in 1960, and, after the machine is "turned up" and tested, operation should begin later that year...
...accelerator, electrons whirl around on a constant orbit of 236-foot diameter between a series of 48 strong-focusing magnets. The circular tunnel which encloses it will have a powerhouse in the middle to supply the energy for the magnets. The accelerator tunnel and the powerhouse will be connected by four radial tunnels...
