William A. Johnson Company

William Johnson began his x-ray career at Stanford Linear Accelerator working as a design engineer, then carried that knowledge on to the Schonberg Radiation Corp (SRC). That was 50 years ago and some of the x-ray equipment he built still exists today. After leaving SRC, he, with another partner founded “High Energy Services Corp” specializing in field x-ray services and manufacturing custom x-ray equipment for very unique applications. Now, somewhat retired, Mr. Johnson is a consultant and assists U. S. Photon with the technical aspects of producing and controlling x-rays.
