LRI Staff and Students Summer 1992. Among others
are Paul Davis, Bud Magera, and Bill Mackie.
Applied Physics Technologies, incorporated in 1995 by William Mackie, Ph.D. and Gary Cabe, is an outgrowth of research conducted for over two decades at Linfield Research Institute on transition metal carbides, thermionic and field electron sources. Demand for these products by industry, government and academic researchers led to the formation of APTech.
As a spin-off from Linfield Research Institute (LRI), APTech upholds a heritage of leadership in field emission research dating to the post-WWII era. Early successes by Walter Dyke led to the founding of LRI in 1955 to focus on field emission technology. Francis Charbonnier joined Dyke and others not long afterwards, and though now retired, still maintained an involvement with research and development at LRI and here at APTech. Five decades of on-going field emission research from LRI has spawned a community of notable surface scientists and commercial enterprises in McMinnville and the broader Portland, Oregon, area. APTech maintains close ties to the other members of this community, working together to further advance the science of electron emission and the technology of electron sources.
