Abstract (en)

[origin: EP0691801A1] A micro-focused X-ray source includes an X-ray tube (10) and a target voltage generating circuit (112). The target voltage generating circuit (112) has a double invertor structure configured by a step down invertor (410) and a push-pull invertor (420) which generates little heat and thus no cooling fan needs to be provided. The circuit includes Cockcroft-Walton circuitry (20a) in which diodes and capacitors making up this circuitry are fixedly mounted on insulation boards (20b) so that the positions of the diodes and capacitors will not shift during their moulding into an insulation block. <MATH>
