Cancer Research

A seventy million volt synchrotron capable of generating the most powerful x‐ray beam ever to be applied to the treatment of cancer is being assembled at the University of California School of Medicine in San Francisco, according to announcements from the University and from the General Electric Laboratories, where the accelerator was designed and constructed. The instrument and its associated laboratory are housed in a specially constructed two‐story building at the medical school. Total cost of the machine and the building, all financed by the Atomic Energy Commission, is about one‐half million dollars. The University's medical research project which will make use of the synchrotron is under the direction of Robert S. Stone, professor of radiology and a pioneer in the application of nuclear physics in medicine.
