Title

new magnetic spectrometer at 88" cyclotron

Description

The magnetic spectrometer at the 88-inch cyclotron with Bernie Harvey (l.) and Fred Becchetti. The beam enters through pipe on right and strikes target (center). Particles coming from nuclear reaction are analyzed by the spectrometer magnet and then detected and identified by the focal plane counter system. The spectrometer is one of several new devices recently added to the 88-inch cyclotron to make it possible to do research on heavy ions. The complete system includes an internal heavy ion source, energy- analyzing magnets, the spectrometer with a novel detection system that identifies particle by atomic number, atomic mass, and energy. The focus of the new heavy-ion research program will be to examine the remains of the bomarding particle to learn more about nuclear structure. Principal investigators will include Bernard Harvey, Joe Cerny, Cornelius Tobias, and Buford Price, among others. The 88- inch cyclotron is a variable energy, spiral- ridge machine of the sector-focused type. Such machines maintain very high beam intensities and fairly high beam energies. The machine first became operational in 1961. The design and construction of the 88-inch cyclotron was led by physicist Elmer Kelly and engineer Richard Burleigh. The experimental program at the 88-inch includes studies of nuclear reaction mechanisms, scattering and absorption of beam particles, and production of many radioactive and stable isotopes.
