Advanced Energy Release “Industrial Ion Sources and Their Applications for DLC Coating” White Paper
June 22, 1999—A new white paper, “Industrial Ion Sources and Their Applications for DLC Coating”, has been published as part of a series of technical white papers by Advanced Energy Industries, Inc. (Nasdaq: AEIS).

This white paper discusses the next generation of ion-beam sources which feature low maintenance, high yield functions—with process performance, quality, and cost of ownership benefits. These robust sources are suitable for a broad range of industrial applications because of their ability to operate without external electron emitters. Thus, they can work in reactive gas environments, particularly oxygen.
