Effective hard x-ray spectrum of a tabletop Mather-type plasma focus optimized for flash radiography of metallic objects

Mostrar todas las versiones(3)

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 Gd2 O2 S:Tb phosphor intensifier screen. It was found that the radiation has relevant spectral compon...
