Recent Results on Simulations of High Intensity Beams in Cyclotrons
نویسنده
چکیده
A summary of activities that envisage a source to target simulation of the PSI cyclotron complex is presented. Our aim is to gain a quantitative understanding of complex phenomena in our machines and beam lines, including three-dimensional space charge effects, beam cavity interaction, collimation, beam neutralisation and extraction mechanism. An introduction to the mathematical and computational methods used is presented together with a comparison of simulations with measurements.

Polymeric Materials Research with Cyclotrons P.yu.apel
Ion beams from cyclotrons as a source of radiation with extremely high linear energy transfer (LET) are considered. Basic processes of energy dissipation in heavy ion tracks are reviewed and the main parameters characterizing the effects of accelerated heavy ions on matter are given in relation to the effects of low-LET radiation. Modification of polymers by using cyclotron beams is discussed w...
متن کاملAnalytic fluid theory of beam spiraling in high-intensity cyclotrons
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Using a two-dimensional fluid description, we investigate the nonlinear radial-longitudinal dynamics of intense beams in isochronous cyclotrons in the nonrelativistic limit. With a multiscale analysis separating the time scale associated with the betatron motion and the slower ...
متن کاملA Study of the Cyclotron Gas-Stopping Concept for the Production of Rare Isotope Beams
The proposed cyclotron gas-stopping scheme for the efficient thermalization of intense rare isotope beams is examined. Simulations expand on previous studies and expose many complications of such an apparatus arising from physical effects not accounted for properly in previous work. The previously proposed cyclotron gas-stopper geometry is found to have a near null efficiency, but extended simu...
متن کاملModelling of Electron and Ion Dynamics in the Electron Cyclotron Resonance Ion Source by Means of Pic-self Consistent Numerical Simulations*
The properties of Electron Cyclotron Resonance Ion Sources (ECRIS) plasmas, up to now, have been largely studied on the basis of a global approach. However the design of new generation sources, able to provide high intensity beams of multiply charged ions, requires a more accurate investigation of both electron and ion dynamics. Recent experiments have demonstrated that even slight frequency’s ...
متن کاملHigh Intensity Ion Beam Injection into the 88-inch Cyclotron
Low cross section experiments to produce super-heavy elements have increased the demand for high intensity heavy ion beams at energies of about 5 MeV/nucleon at the 88-Inch Cyclotron at the Lawrence Berkeley National Laboratory. Therefore, efforts are underway to increase the overall ion beam transmission through the axial injection line and the cyclotron. The ion beam emittance has been measur...
