Simulation of H- ion source extraction systems for the Spallation Neutron Source with Ion Beam Simulator.
A three-dimensional ion optical code IBSimu, which is being developed at the University of Jyväskylä, features positive and negative ion plasma extraction models and self-consistent space charge calculation. The code has been utilized for modeling the existing extraction system of the H(-) ion source of the Spallation Neutron Source. Simulation results are in good agreement with experimental da...
متن کاملSimulation of ion beam injection and extraction in an EBIS.
An example simulation of Au+ charge breeding using FAR-TECH's integrated EBIS (electron beam ion source) modeling toolset is presented with the emphasis on ion beam injection and extraction. The trajectories of injected ions are calculated with PBGUNS (particle beam gun simulation) self-consistently by including the space charges from both ions and electrons. The ion beam, starting with initial...
متن کاملBeam simulation studies of ECR beam extraction and low energy beam transport for FRIB.
To meet the beam power requirements of 400 kW at the fragmentation target for facility for Rare Isotope Beams (FRIB), simultaneous acceleration of two-charge states should be used for heavier ions. These intense multi-charged ion beams will be produced by a 28 GHz electron cyclotron resonance (ECR) ion source at a high voltage of 35 kV. After extraction, the ion beam will be pre-accelerated to ...
متن کاملThree Dimensional Simulation of Ion Beam Extraction from an Ecr Ion Source
Accurate prediction of ECR ion extraction behavior is important for high current density operation and subsequent beam transport calculations. In this paper we review the combined electric and magnetic space charge beam simulation of ion beam formation from an ECR ion source with a multi-electrode extraction system. Included in the simulation is the influence of secondary charged particles gene...
متن کاملKinetic Plasma Simulation of Ion Beam Extraction from an Ecr Ion Source
Designing optimized ECR ion beam sources can be streamlined by the accurate simulation of beam optical properties in order to predict ion extraction behavior. The complexity of these models, however, can make PICbased simulations time-consuming. In this paper, we first describe a simple kinetic plasma finite element simulation of extraction of a proton beam from a permanent magnet hexapole elec...
