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 کاملModified extraction geometry in a radio-frequency ion source
2014 This paper is to show that a number of plausible arguments supporting the use of Bayly and Ward’s extraction geometry in radio-frequency ion source can be put forward. The ThonemannHarrison and the Schmidt-Eyrich version of this method have been compared in a series of measurements from the points of view of working parameters and beam characteristics. Current, gas supply rate, mass spectr...
متن کاملExperiments on neutralized beam extraction from a laser ion source
Particle loss due to space charge effects is a severe problem in the low energy section of accelerators. The extraction system and beam transport sections are the most sensitive parts. Especially for the case of a laser-ion source (LIS) the extraction of ions from very dense plasma can lead to a high current density in the extraction gap. To make use of this high current density (i.e. to maximi...
متن کاملNew Dual-type Electron Cyclotron Resonance Ion Source for a Universal Source of Synthesized Ion Beams*
A new dual-type source has been constructing on the basis of electron cyclotron resonance (ECR) plasma for producing synthesized ion beams in Osaka Univ. Magnetic field in the 1st stage consists of all permanent magnets, i.e., cylindrically comb shaped one, and that of the 2nd stage consists of a pair of mirror coil, a supplemental coil and the octupole magnets. Both stage plasmas can be indivi...
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...
