Design, hard x-ray source characterization and applications of a plasma focus tailored for flash hard x-ray imaging

Mostrar todas las versiones(2)

A low-energy (2.5 kJ and 30 kV) plasma focus tailored to perform as a hard x-ray radiation source for flash radiography, is presented. The device is operated in a mixture of deuterium and argon to enhance its performance. A study of the breakdown properties of the discharge chamber is presented. The...

The device is operated in a mixture of deuterium and argon to enhance its performance. A study of the breakdown properties of the discharge chamber is presented. The hard x-ray emission was experimentally characterized by means of both: (i) the spatial location of the radiation source inside the discharge chamber and (ii) an effective energy analysis based on systematic measurements of the attenuation of the hard x-ray output through different metallic pieces.
