Title

Federal Telegraph 80-ton magnets

Description

While Lawrence was studying the design of several large and expensive magnets, he learned that a huge magnet yoke stood idle at Palo Alto. He was able to secure the yoke through Leonard T. Fuller, professor of electrical engineering at the University, who was also a vice president of Federal. The gift came as it was, eighty tons of metal fifty miles from Berkeley. Robert Gordon Sproul, president of the University, agreed to house the magnet and to pay for the power to run the cyclotron. (The preceding information was excerpted from the text of the Fall 1981 issue of LBL Newsmagazine.) Workmen at Federal Telegraph smoothing two castings for 80-ton magnets. The tall central pole had to be machined down for use in the cyclotron. This magnet was used for the the 27-Inch and 37-Inch Cyclotrons in the early 1930's. It is now on display in the entry of the Lawrence Hall of Science.
