APTech's Key Staff

William Mackie ~ President & Co-founder

Bill received his PhD from OGI (Oregon Graduate Institute of Science and Technology, now a division of Oregon Health and Sciences University) in Applied Physics in 1987. He joined the faculty at Linfield College and conducted research on transition metal carbides at Linfield Research Institute. He has a lengthy list of publications in the areas of transition metal carbides, field emission cathodes, thermionic sources, and thin film uses of refractory materials. Along with his full-time duties at Applied Physics Technologies, he is also professor of physics at Linfield College and a former director of the Linfield Research Institute.

Gary Cabe ~ Vice President & Co-founder

Gary received his BA in Physics and Mathematics from Linfield College in 1972, followed by two years of research in low temperature physics at the University of Oregon. He came to Linfield Research Institute in 1991. Prior to that time he was with the FEI Company for 14 years. He has an extensive background in manufacturing technology, field emission cathodes and guns, UHV systems, and electronic components.

Gerald (Bud) Magera ~ Senior Research Scientist

Bud received his PhD from OGI (Oregon Graduate Institute of Science and Technology, now a division of Oregon Health and Sciences University) in Electrical Engineering in 1993. The following 13 years were spent at the FEI Company as a Research Scientist in the Beam Technology Division. Areas of expertise include electron and ion source development, charged particle optics, high voltage systems, vacuum technology, and surface physics and chemistry related to electron and ion emission. Bud has been granted five electron source patents.

Kevin Kagarice ~ Senior Research Scientist

Kevin joined Applied Physics Technologies in 2002.  He received his BS in physics from the University of North Texas in 1995, then spent seven years at the FEI Company, most recently as a Development Engineer working on the design and manufacturing of electron focusing columns.  Kevin has an extensive background in both thermionic and field emission cathodes and guns, including design, modeling, and optimization of electron optics.  His recent emphasis has been characterizing emission properties of transition metal carbides.

Paul Davis ~ Senior Research Consultant

Paul received his PhD in Physics from Washington State University in 1972, with emphasis on surface physics. After a postdoctoral year at the Fritz-Haber-Institut of the Max Planck Gesellschaft in Berlin, he spent two years at the University of Bristol in the UK and three years at NASA-Ames Research Center in California. Paul has been involved in several areas of research, including surface physics and chemistry, electron emission phenomena, surface analytical techniques, low work function materials, and energy conversion technologies. He settled at the Oregon Graduate Institute (now part of Oregon Health and Sciences University) in 1978. In 1991, he moved to Linfield College (his undergraduate alma mater), where he continued research and teaching. Paul retired from Linfield in 2005 with the rank of Professor Emeritus of Physics. He is a former director of the Linfield Research Institute. Paul presently serves as a consultant to Applied Physics Technologies on matters pertaining to thermionic and field emission cathodes and applications.

Alana Celia ~ Director of Marketing & Business Development

Alana is a graduate of Linfield College where she earned a BS in Physics and Business Management. Most recently she worked at ChemPoint.com in their Operations and Marketing & Sales department. As an undergraduate, she gained research experience in thermionic electron emission, an area valuable for this position. Alana also has a strong background in business related topics; she completed a marketing and management internship that focused on creating business Internet platforms for products, participated in a molecular physics internship at SRI International, and spent a summer analyzing biotechnology clusters at Keck Graduate Institute.
