Light-ion Driver Accelerator for
|ORIC Mission Statement
The primary mission of the Oak Ridge Isochronous Cyclotron (ORIC) is to serve as a driver for the production of radioactive ion beams (R.I.B.s). ORIC provides high intensity proton, deuteron, and alpha particle beams to a target-ion source assembly that is located on the R.I.B. injector platform. The reaction at the target produces radioactive atoms which are then ionized and accelerated.
|The ORIC Concept
The Oak Ridge Isochronous Cyclotron (ORIC) is a variable energy, multiparticle accelerator which was completed in 1962. The isochronous, or azimuthally varying field (AVF), cyclotron concept was first proposed in 1938 by L.H. Thomas. Isochronism refers to the constant orbit frequency of circulating ions obtained by radially increasing the magnetic field to compensate for relativistic increases in ion mass. Since a radially increasing magnetic field defocusses the beam, azimuthal variations in magnetic field are required to focus the beam for circulation without losses and for efficient extraction. ORIC was one of the first isochronous, or AVF, cyclotrons produced.
