X-ray phase contrast imaging solves the basic problem of conventional X-ray imaging, i.e. low image contrast arising from small absorption differences. For years X-ray phase contrast imaging was thought to be restricted to synchrotron radiation facilities, but a new approach was recently developed a

โฆ Synopsis
Plasma Focus generators (PFGs) are the most powerful and effective sources generating simultaneously short bursts of X-rays and fast neutrons. They are distinguished by small size of emitting area ($1 mm) and short burst duration (o100 ns). That is why they are very perspective for investigating dynamic phenomena with radiographic methods with high time resolution. This paper demonstrates the feasibility to carry out X-ray and neutron radiography simultaneously on a plasma focus generator with the energy in the capacitor bank of about 10 kJ and fast neutron yield of E10 11 n/pulse.
