The design and performance characteristics of a set of high intensity flash X-ray systems will be discussed. At present, six (6) systems are available with output voltages in the range of 75 kV to 1200 kV. Peak current is 10 kA and exposure time 20 ns. Demountable X-ray tubes are being used to increase flexibility and reduce operating costs. Typical applications are found in areas such as ballistics, detonics, quality control, etc.
