Improved Source Magnetics Reduce Beam Curl
A range of new sources have been introduced which incorporate a significant change from the traditional magnetic field design, providing a much straighter beam path through the melt material, thus increasing the usable portion of the melt inventory and producing a more uniform and predictable evaporant cloud. These sources can be supplied with the optional Arc-Suppression or self-sealing cover plate.

Arc Free Upgrade
A source with the Arc Free is ideal for many applications, such as for optical coating and for ion plating without a pressure barrier. The reduction in arcing results in improved film quality, improved yields, and fewer arc-related maintenance issues.
Self-Sealing Cover Upgrade
An optional self-sealing cover plate is available for applications where cross contamination between materials is a concern.
