X-ray generator with integrated flow sensor

Tube (10) X-ray generator comprising a chamber (11) of vacuum with a cathode (12) and an anode (13) placed in the chamber (11) vacuum emitting cathode (12) a beam (14) e towards the anode (13), comprising the anode (13) of an object (13) which emits X (16) radiation when hit by the beam (14) e, spreading the X (16) radiation outside the chamber (11) vacuum through the wall (11) of the chamber through a window (17; 30; 31; 32; 33; 34) based transmission diamond, wherein a sensor (21; 121) X-ray based diamond is integrated into the window (17) of transmission based on diamond.
