David L. Bruhwiler Tech-X

David L. Bruhwiler is the Vice President for Accelerator Technology at Tech-X Corp. He has 20 years of experience in the development of algorithms and high-performance software for the design and simulation of particle accelerators and other beam and plasma devices. From 1992 through 1997, Dr. Bruhwiler designed rf photocathode electron guns and subsequent beamlines for the generation of high charge (>1 nC) sub-picosecond electron pulses.

Upon joining Tech-X Corp., Dr. Bruhwiler co-developed a unique algorithm for modeling particle trajectories far from the accelerator axis. He also co-developed the electrostatic and electromagnetic PIC codes OOPIC Pro and VORPAL, including the use of MPI messaging and the parallel sparse matrix solver Aztec, as well as the co-development of multiscale algorithms. Dr. Bruhwiler has used these codes extensively to study plasma-based particle accelerator concepts. He is a member of the VORPAL development team and recent work has included implementation of a 4th-order electromagnetic update, participation in implementation of the Dey-Mittra algorithm for cut-cell boundaries and modeling photocathode electron sources. A recent focus has been the development, implementation and use of algorithms in VORPAL for modeling electron cooling physics.
