David Bruhwiler, Ph.D.
Vice President, Accelerator Technology
David Bruhwiler earned a doctorate in plasma and accelerator physics from the University of Colorado at Boulder in 1990. Dr. Bruhwiler has fifteen years of experience in the development of high-performance Fortran and C++ codes for the design and simulation of particle accelerators, free-electron lasers (FEL) and other beam and plasma devices.
Dr. Bruhwiler joined Tech-X Corp in the Fall of 1997, where his work has focused on the development of particle-in-cell (PIC) codes for simulating high-power RF devices and advanced concepts for plasma-based particle acceleration, with emphasis on parallel computing techniques, graphical user interfaces (GUI) and 3-D visualization.
