Experiments with rf ovens in ECR ion sources

Review of Scientific Instruments, 2004
A 34 mm diameter radio frequency (rf) oven system previously developed on bench was inserted and tested into the Electron Cyclotron Resonance (ECR) Ion Source Alice, producing beams from natural copper and silver samples; charge range was typically i=10–13 for copper and i=10–19 for silver, which well compares to previous source yield for xenon ...

The Matching Unit for the RF Ion Source at HUST

Journal of Fusion Energy, 2015
A revised L mode matching unit is used for the radio-frequency (RF) ion source test facility at Huazhong University of Science and Technology (HUST). The revised matching unit is composed of a series capacitance, a parallel capacitance and a RF transformer.

A note on ion beam extraction from an RF ion source

Nuclear Instruments and Methods, 1979
Some measurements of ion beam intensities extracted from a water-cooled rf ion source are presented. These measurements lead to an extraction device, which results in an increase of more than 50% of the extracted ion current. This improvement indicates a possibility of extracting high brilliance ion beams from rf or duoplasmatron ion sources.

CHARACTERISTICS OF LOW POWER RF ION SOURCE

Problems of Atomic Science and Technology
The main characteristics of a low-power inductive RF ion source designed for use in a compact nuclear microprobe at the IAP NASU are presented. The source operates at a frequency of 45 MHz with RF power below 10 W. The extracted beam current reaches up to 3.5 µA through a 0.6 mm diameter aperture. The beam is composed of 1H+, 2H+, and 3H+ ions, and the

RF H⁻ Ion Source with Saddle Antenna

2010
In this project we are developing an RF H⁻ surface plasma source which will synthesize the most important developments in the field of negative ion sources to provide high pulsed and average current, high brightness, good lifetime, high reliability, and higher power efficiency.

Development and applications of the RF-driven ion source

The 30th International Conference on Plasma Science, 2003. ICOPS 2003. IEEE Conference Record - Abstracts., 2003
Summary form only given, as follows. RF driven ion sources have been developed at the Lawrence Berkeley National Laboratory for more than a decade. This type of ion source can be operated with 2 or 13.5 MHz in either cw or pulsed mode for positive or negative ion beam production.
