Title: Innovations by Robert A MacGill
Introduction
Robert A MacGill is a notable inventor based in Richmond, CA (US). He has made significant contributions to the field of plasma technology, holding a total of 8 patents. His work primarily focuses on the development of advanced cathodic arc plasma sources and filtration systems.
Latest Patents
One of his latest patents is the Miniaturized Cathodic Arc Plasma Source. This innovative device features an anode constructed from multiple spaced baffles that extend beyond the active cathode surface. The design allows most macroparticles to pass through the gaps between the baffles, effectively filtering out contaminants from the plasma stream. The cathode is designed with a small diameter, approximately ¼ inch (6.25 mm), which ensures that the plasma output remains localized. The source operates in pulsed mode at high currents, around 1 kA, and is capable of depositing ultrathin amorphous hard carbon (a-C) films, particularly beneficial for the magnetic storage industry.
Another significant patent involves Filters for Cathodic Arc Plasmas. This invention addresses the contamination of cathodic arc plasmas with macroparticles. MacGill's design includes a magnetic plasma filter that utilizes an open-architecture, bent solenoid filter, which enhances the efficiency of macroparticle removal. The system is complemented by an output conditioning system that expands the filtered plasma beam, making it suitable for various applications in the magnetic storage sector.
