Title

60-inch Crocker cyclotron ends run

Description

Hail and farewell to Crocker's 60-inch cyclotron came after 23 years of faithful service, on June 30, 1962. Just prior to shutdown, a group of old friends take a last look at the machine which played such an important role in their lives: (l. to r.) Bob Thornton, John Lawrence, Don Cooksey, Ed McMillan, and Bernard Harvey. Harvey was in charge of the last experiment performed at the cyclotron. The 60-inch cyclotron accelerated its last beam on Saturday, June 30, 1962. It began operation ont the same day in 1939, 23 years earlier. After the shutdown, the cyclotron was dismanted and shipped to UC Davis, where it became the basis of a new spiral-ridge accelerator. The 60-inch cyclotron had been the site of many important developments, including the creation of seven new elements; the creation, production and distribution of artificial radioisotopes; tracer experiments; treatment and control of disease; andstudies of the biological effects of radiation.
