Hard x-ray spectrum emitted by a plasma focus optimized for flash radiography

Mostrar todas las versiones(2)

The effective spectrum of the hard x-ray output of a Mather-type tabletop plasma focus device was determined from attenuation data on metallic samples using commercial radiographic film coupled to a Gd2O2S: Tb phosphor intensifier screen. It was found that the radiation has relevant spectral compone...
