...Russia. Physicist Luis Alvarez of the University of California last week held up a strange photograph that looked a little like a nonobjective drawing. It was in fact a picture of one of nature's innermost secrets. Made possible by use of California's new 6-ft. liquid hydrogen bubble chamber (TIME, July 13), it showed for the first time the birth, death and after effects of an anti-lambda particle...
...Berkeley, Calif., one of the world's biggest, most complex and most dangerous scientific instruments was ready for full operation for the first time. Its name was a tongue twister: the liquid hydrogen bubble chamber, designed and built by the University of California's Radiation Laboratory. In the next week or so, a beam of antiprotons from Berkeley's great 6 billion-volt Bevatron will pass through a pipe 200 ft. long, enter an odd-looking building and strike into a glass-topped metal bathtub containing 150 gal. of liquid hydrogen. As the antiprotons travel through...
...Luis Alvarez, associate director of the Radiation Lab, was not in the audience. He was at the White House delivering a strobo-scopic gadget he had invented to improve President Eisenhower's golf game. But Alvarez knew about the Glaser paper, and had plans for improvements. The best liquid to use, he thought, was not ether; it was pure liquid hydrogen, which contains no carbon or oxygen atoms to confuse researchers...
...Liquid hydrogen is rugged stuff to fool with, so cold (boiling point: -252.7° C. at atmospheric pressure) that steel cracks on sudden contact. It must be elaborately refrigerated or it will flash into vapor. Even a small leak is highly explosive. The 150 gal. in Berkeley's chamber have the explosive power...
...around like a mechanical dinosaur. Leak detectors were installed everywhere to watch for escaping hydrogen; 104 alarm circuits inside the machine flash lights, ring bells and honk horns at the slightest hint of trouble. In a serious emergency (e.g., the failure of the refrigeration system) the entire stock of liquid hydrogen can be dumped through a pipe down a canyon and into a spherical tank. If all precautions fail, a hydrogen explosion may not wreck the whole apparatus. The top of the building is made of mint green plastic, is designed to blow off easily, allowing the blast to spend...
