Ion Beam Dynamics in Polyharmonic Field of Linac
نویسنده
چکیده
This paper describes the problem of ion RF focusing in the axisymmetric RF field involving one synchronous and several nonsynchronous harmonics. The influence of nonsynchronous harmonics on ion beam dynamics is studied by means of 3D effective potential, which is obtained for smooth approximation. The motion equation is presented in Hamilton’s form. The possibility of simultaneous transverse focusing and phase stability for accelerating ion beam in the RF field without the synchronous harmonic is shown.

Beam dynamics simulations of the proposed Rare Isotope Accelerator (RIA) [1] driver linac have been done. The RIA driver linac is designed to accelerate stable ion beams from proton to uranium to final energies of 400 MeV/u for the heaviest and about 900 MeV/u for the lightest ions with beam powers of 100 to 400 kW. Two stripping sections are used to increase the charge state of heavy ions and ...
متن کاملMultiple-Charge Beam Dynamics in an Ion Linac*
There is demand for the construction of a mediumenergy ion linear accelerator based on superconducting rf (SRF) technology. It must be capable of producing several hundred kilowatts of CW beams ranging from protons to uranium. A considerable amount of power is required in order to generate intense beams of rare isotopes for subsequent acceleration. At present, however, the beam power available ...
