DOI: 10.1063/1.3047822
After a year of effort physicists at the Princeton‐Pennsylvania accelerator have succeeded in extracting the synchrotron’s beam. The method of extraction, which is the same as the one used on the electron accelerator at Frascati, employs betatron oscillation to blow up and spill the beam. Specifically the radial betatron resonance,
