Applied Physics Technologies, Inc.

Corporate Profile

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. Increasing demand for these products by the 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. APTech's greatest appeal is its high development and technological capabilities. APTech's key strength is its ability to design and manufacture a variety of specifications, including single-crystal tip and electron source assembly.
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.
