Abstract

An inductively coupled plasma charged particle source for focused ion beam systems includes a plasma reaction chamber with a removably attached source electrode. A fastening mechanism connects the source electrode with the plasma reaction chamber and allows for a heat-conductive, vacuum seal to form. With a removable source electrode, improved serviceability and reuse of the plasma source tube are now possible.
