What the U.S. Public Health Service recommends, and the A.D.A. approves, is a machine that delivers an X-ray beam 2¾ in. in diameter. Extra-heavy aluminum filters weed out useless rays, and lead shielding keeps all radiation within bounds. The patient gets only a small fraction of the radiation that was sprayed out of pre-1958 machines...
...Dallegret's La Machine is a far heftier entree. A Frenchman, now designing for Montreal's Expo 67, Dallegret has designed a device that looks like a giant metal steeplechase hurdle, weighs half a ton, and is priced at $27,000. It consists of two slender beams of anodized aluminum, 30 ft. long by 2 ft. high, braced between uprights. A cool piece of pure structure, the object has all the contemplative imagery of an I beam, but it has an inner electronic life. The narrow six-inch gap between the aluminum beams is brightly lit by hidden...
Near the output end, each sample drops into a tube on the rim of a colorimeter that looks like a twelve-spoke wheel. A powerful light flashes a beam through the tubes, and photo-electric cells measure the intensity of the transmitted light. A computer converts these readings into values for the pen to draw on the chart paper (see diagram...
...distracted by girls and baseball"). Silverstein is one of the few concertmasters to work his way up from the ranks; he joined the Boston string section in 1955, ascended to the first chair in 1962. Says Boston Symphony Conductor Erich Leinsdorf: "He has some sort of beam or antenna, so that he knows what I want almost before...
Sound & Fury. Using 700-ton magnets, Harvard's cyclotron fires a proton beam with the force of 160 million electron volts. But after leaving the cyclotron, the protons travel a precise and predictable distance before they release their power. Careful positioning of the patient allows the beam to pierce the skin with little damage before releasing all its energy and destroying a specific target deep inside the body-such as the pituitary gland, perhaps, or a brain tumor...
