HILL AIR FORCE BASE, Utah
HILL AIR FORCE BASE, Utah - Mr. John Law, an X-Ray physicist at the Survivability and Vulnerability Center, performs maintenance on the Large Flash X-Ray machine used to test missile components. The machine, when fully prepped for use, is full of oil and can provide some 5-million volts and 100,000 amps for testing purposes. As part of the cleaning process, he discharges "left over" high-voltage charges in the capacitors. (Photo by G. A. Volb)
