Abstract:
A radiation head for the generation of predetermined electromagnetic radiation comprisinga radiation generation chamber,an anode means having a tip end component,a cathode means, anda trigger electrodesaid chamber having a radiation transmitting window of a material preferentially transparent to a predetermined radiation generated in said chamber and through which the predetermined radiation may be emitted from said radiation head, said anode means and cathode means being disposed in said chamber, said tip end component comprising a material able to facilitate, in response to a pulse voltage applied between said anode and cathode, the generation of electromagnetic radiation, said tip end component, said cathode means and said trigger electrode being space apart from each other by a respective predetermined distance, characterised in that said radiation head comprises capacitor means for storing electric energy supplied by a high voltage source, said capacitor means comprising a terminal electrode for connection to said anode means, and said anode means being directly electrically connected to said terminal electrode of said capacitor means so as to be integral with the capacitor means.
