Glenn Scheitrum, PhD - VP of Manufacturing

Dr. Scheitrum joined Varian Medical systems in August, 2008. He received B.S. degrees in Psychology and Electrical Engineering from Drexel University and M.S., Eng., and Ph.D. degrees in Electrical Engineering from Stanford University. He participated in the Air Force Thermionic Research (AFTER) program at Stanford. His industrial sponsor for the AFTER program was Litton Industries.  At Litton, he headed the fast wave device research group. He developed the advanced centerpost (ACP) gun that produced the hollow, axis encircling electron beam required for the harmonic gyroklystron. He holds two patents on the harmonic gyroklystron.  Dr. Scheitrum joined the Stanford Linear Accelerator Center (SLAC) in 1996. He worked on RF breakdown, a gigawatt annular-beam-klystron program, LIGA fabrication of mm wave sources, sheet beam klystron development, and 3D modeling required for sheet beam RF sources.

At Varian Medical Systems, Dr. Scheitrum worked with Zane for the Security & Inspection Products group which produces X-ray sources for non-destructive testing and cargo scanners

Francis Tsang, PhD - Founder/CTO

Francis is a nuclear physicist who has worked within the Department of Energy (DOE) and other government agencies for more than twenty-five years. Specific projects he has been involved with include remote sensing technology and applications; foreign space systems; foreign science and technology infrastructure assessments; foreign nuclear weapon programs; energy weapon signatures detection and analysis (charged and neutral particle accelerators); tagging technologies and applications; arms control systems and technologies; adversary technology system assessments; fusion reactor and blanket technologies; radiation detection technology R&D; fiber-optic technologies; ultra-fast (picoseconds) electronic system R&D; active and passive interrogation of spent nuclear fuel, and science and technology regarding economic competitiveness analysis. Dr. Tsang’s experience and insights has resulted in novel energy production methods as well as the isotope production process.

Zane Wilson - Founder/CEO

At Stanford, Zane started as a summer intern student for the US Department of Energy (DOE) at the Stanford Linear Accelerator Center (SLAC) at Stanford University, advancing to head of all klystron operations in the Klystron Department. The Klystron/RF Department at SLAC is responsible for development & production of high power RF systems. Also during his 20 years at the DOE he was involved with the DOE’s NNSA's nonproliferation mission and worked with closely with Dr. Tsang. After SLAC he joined Varian Medical Systems in Palo Alto and was assigned to Security & Inspection Products group in Las Vegas where he held several director positions.  Zane also worked for Applied Materials, the semiconductor company, for a short time, as a the engineering manager in AMAT’s pilot manufacturing. 

Our goal is simple, find a better way to make the isotopes we need.

Comprehensive isotope development, fabrication, production and support.


GMIS' core capabilities include neutron physics, nuclear interaction studies (photons, electrons, neutrons, and protons), neutron filtered beam production and applications, neutron generator applications, electron accelerator design and fabrication, radio-frequency systems and equipment design.
