The energy spectra of X-rays generated by the impact of electron beams on high- and medium-Z targets following the pinch implosion of Plasma Focus (PF) devices are discussed in terms of the possible mechanisms of X-ray production following electron impact ionization. In addition, the temperature measurement of the PF inner electrode is reported and some results have been proved useful in order to optimize the device functionalities.
