Abstract
A NEW giant cyclotron has recently been put into operation at the Department of Terrestrial Magnetism of the Carnegie Institution of Washington. The new cyclotron, one of the two largest in operation in the world (the other being at Berkeley, California), generates particles of 15,000,000 electron volts energy, permitting the most precise measurements ever made of the forces released by atomic disintegration. The cyclotron itself weighs more than 225 tons, has an overall height of 12 ft.; it is 30 ft. long and 20 ft. wide. It took four years to build, at a total cost of 500,000 dollars for the cyclotron, its appurtenances, and, the special three-story building housing the equipment and instrument shop. The magnet is made up of four iron castings, the largest weighing more than fifty tons. Surrounded by this heavy magnet is the accelerating chamber, about sixty inches in diameter, in which atomic particles are produced. The cyclotron is housed ten feet below ground.
