An Automatic Real Time Impedance Matching System for Use in an RF Electrostatics Accelerator Ion Source

An 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...

Helicon Source for Ion Propulsion

Electric thrusters are usually in one of two forms: gridded ion thrusters or Hall thrusters. Each of these accelerates ions and requires an injector of electrons to neutralize the ion beam. Ambipolar thrusters eject neutralized plasmas with equal numbers of ions and electrons. Helicon thrusters are a new type being developed which utilize both the high ionization efficiency of magnetized helico...

Emergency power source for an ion vacuum pump.

This note describes a simple high-voltage dc generator which serves as an emergency power source for an ion vacuum pump during power interruptions, or failure of the main supply.

Use of an Ecr Ion Source for Mass Spectrometry

At ANSTO we have developed an Electron Cyclotron Resonance (ECR) ion source to investigate new concepts for mass spectrometers designed to measure isotopic ratios of elements such as carbon, nitrogen and oxygen. The low pressure ECR plasma presents particular challenges when used for mass spectrometry. The elements we are interested in measuring are typically present as residual gas in vacuum s...
