A radiogenic unit includes an X-ray tube having an anode disposed at a first end thereof and a cathode disposed at a second end thereof, a high-voltage supply circuit which supplies power to the X-ray tube in single pole mode and which includes a heating transformer for the cathode, and a casing. The casing includes first and second parts imperviously sealed against fluids and X-rays and hermetically sealed to one another. The first part is made of an electrically insulating material, has a first cavity formed therein in which is housed the X-ray tube, and houses a conductive element for the anode. The second part is made of an electrically insulating material and has additional cavities formed therein in which are housed the high-voltage supply circuit. Preferably, the X-ray tube is shielded by three cylinders of different potentials.

Radiogenic unit

A radiogenic unit comprising an X-ray tube with fixed anode made of copper and its circuit for high-voltage supply in single-pole mode, these elements being placed in two parts that are imperviously sealed against fixed against X-rays, secured to each other in a hermetically sealed way. The first part, made of an electrically insulating material, has cavities for the housing of the X-ray tube and its supply circuit. The second part, made of material with high thermal conductivity, comprises a cavity for the housing of the tube, the anode of which is connected to a thermal and electrical frame. It can be applied particularly to radiology instruments.
