General Electric Research Laboratories in Schenectady last week unveiled a giant new X-ray machine, 1,000,000 volts strong, the biggest X-ray machine harnessed to industrial research. It is intended to find flaws not in flesh & bone but in big steel castings. G. E.'s 400,000-volt apparatus took an hour to X-ray four inches of steel. The new machine takes less than two minutes...
...Million-volt X-rays, like tigers, are safer when caged. The walls of the 100-ft.-by-35-ft. building housing the machine are 14 inches of concrete plus twelve inches of brick. At one end of the room is a big door of 18-inch concrete encased in one inch of steel. When the machine is ready to go, the researchers leave the room through this door. Then the machine is turned on at a remote control panel...
Early last year news came from Germany, Denmark and France that hit physicists like a punch in the solar plexus. The massive atom of uranium, heaviest of the 92 elements, had been cracked by neutrons (electrically neutral subatomic particles), yielding some 200,000,000 electron-volts of energy per cracked atom (TIME, Feb. 6, 1939). These uranium explosions or "fissions" were most effectively touched off by slow moving neutrons of only one-thirtieth of one electron-volt energy, so that the energy profit was 6,000,000,000 to 1. Prospect of using atomic power-the old dream of sending...
...Hospital, Dr. Charles C. Lund has been investigating the relation of vitamins to the healing of surgical wounds, which may have some bearing on the cancer problem. Dr. Fletcher Colby and Dr. Richard Dresser are continuing their observations on the treatment of cancer of the bladder by the million volt x-ray machine...
Members of the group will assemble in Jefferson 250 and then proceed to the MacKay Laboratories to see the Cyclotron in action deo volente. Professor Saunders says that it has been working well of late hurling an 11,000,000 atom-smashing volt "bullet." The tour will include several other representative pieces of the research constantly in progress at the Laboratories...
