Ion kinetics in a magnetized plasma source
There are regimes of plasma source operation in which the ion motion is controlled by the ambipolar electric eld and ion-atom collisions. This paper presents a derivation of the corresponding ion distribution function and plasma density pro les in the source for a given electron temperature and a given gas ionization rate. Conditions are discussed under which the ion ux is predominantly radial ...
متن کاملDevelopment of a radio-frequency ion beam source for fast-ion studies on the large plasma device.
A helium ion beam source (23 kV/2.0 A) has been constructed for studying fast-ion physics in the cylindrical magnetized plasma of the large plasma device (LAPD). An inductive RF source produces a 10(19) m(-3) density plasma in a ceramic dome. A multi-aperture, rectangular (8 cm × 8 cm) three-grid system extracts the ion beam from the RF plasma. The ion beam is injected at a variety of pitch ang...
متن کاملRf Plasma-based Ion Source Modeling on Unstructured Meshes
Ion source performance for accelerators and industrial applications can be improved through detailed numerical modeling and simulation. There are a number of technical complexities with developing robust models, including a natural separation of important time scales (rf, electron and ion motion), inclusion of plasma chemistry, and surface effects such as secondary electron emission and sputter...
متن کاملThyratron Modulators in Plasma Source Ion Implantation
Plasma Source Ion Implantation (PSII) is an emerging technology which can be used to harden metal surfaces in a conformal manner. North Star Research Corp. (NSRC) is building a unique implanter system for Empire Hard Chrome which will be the first truly commercial implanter of this type. The choice of pulsed power technology for this application is important from the standpoint of both reliabil...
متن کاملAn ion source for molecular effusion studies
An ion source which utilizes a beam of monoenergetic electrons as the ionizing agent was designed and built for use in a 60° sector general utility mass spectrometer. The source was made to be used without a magnetic field to collimate the electron beam. The source is interchangeable with a surface ionization source that was already utilized in the mass spectrometer. Various operating character...
