Ion sources for mass spectrometry II. Filaments for low temperature ion sources

International Journal of Mass Spectrometry and Ion Physics, 1983
Abstract Two low power filaments (thin wire rhenium and LaB 6 ) have been designed to allow a chemical ionization ion source to operate below 100°C. Both filaments simplified analysis of the thermally sensitive compound flurazepam using negative chemical ionization mass spectrometry.

Gas discharge ion source III. Modified Berkeley multifilament ion source

Review of Scientific Instruments, 1978
Total ion current, ion energy, mass and current density distributions, and the impurity content of the ion beams produced by a modified Berkeley multifilament ion source (MFIS) were measured as a function of source configuration, gas pressure, and operating conditions: the ’’best’’ configuration produced beams of 200 mA or more at pressures between 0 ...

Ion sources for use in ion implantation

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1989
Abstract This paper reviews high current ion sources suitable for commercial use. Although the production of high currents of a variety of ions is a vital consideration, this paper focuses on other aspects of ion source performance. The modern ion implanter is a major item of expensive capital equipment, with the ion source being its least reliable ...

Microwave ion source for ion implantation

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1987
Abstract Fundamentals of microwave ion sources used for ion implantation as well as their main features are reviewed and evaluated. Ion sources using plasmas generated by microwave discharge in a magnetic field have many advantageous features. Since they operate even with reactive source materials, they can provide long-life stable ion beams for a ...
