Abstract

We report on the development and implementation of a new beam line at the ORNL Multicharged Ion Research Facility (MIRF) that is floatable at up to -12 kV and injected by a 10 GHz CAPRICE ECR ion source and is part of a major facility upgrade project. With the floating beam line operating at negative high voltage, and the ECR source at ground potential, intense DC beam deceleration into grounded experimental chambers to energies as low as a few eV/q is made possible. The primary application of these ion beams is to study fundamental collisional interactions of multicharged ions with electrons, atoms, and surfaces. Design details of the floating beam line, including source extraction, deceleration optics and voltage isolation will be presented. The novel features of a LABVIEW-based computer control system developed for the floating beam line will be described as well.
