Breaking New Ground in Broad Beam Sources:

Founded in 1978 by Harold Kaufman and Steve Robinson, Kaufman & Robinson’s objective was to perform research to push the boundaries of broad beam source technology. As part of its research and development mission, KRI® undertook the development of ion beam products for use in industrial applications. In particular, KRI® fulfilled contracts to design commercial broad beam sources for use in the vacuum processing of materials such as thin film deposition and plasma etching.

Over the course of two decades, KRI® delivered over 25 commercial ion, plasma, and electron source devices under license agreements with its clients, who manufactured and marketed the products. In 2002, we modified our business model and entered the market with our own ion, plasma, and electron source products.

Today, we leverage our vast technical knowledge to manufacture new, next-generation broad ion beam products. And while the company has evolved and developed a full product line to serve multiple applications and markets, our founders’ commitment to innovation and quality still drive every decision we make and action we take.

Dr. Harold Kaufman Inducted into the NASA Glenn Research Center Hall of Fame

In 2016, NASA recognized KRI founder, Dr. Harold Kaufman, as a trailblazer of ion propulsion by honoring him with induction into the Glenn Research Center Hall of Fame. This fitting tribute noted that Dr. Kaufman had “the rare distinction of inventing an experimental spaceflight hardware system that has not only been demonstrated in testing but is being flown in space today.”
