SOURCE OF BREMSSTRAHLUNG Russian patent published in 2022 - IPC H05H7/22 

FIELD: bremsstrahlung sources.

SUBSTANCE: invention relates to a source of bremsstrahlung. The source contains an electron gun, an accelerating structure, an electron conductor, to the output of which the first flange is vacuum-tightly connected, which is hermetically connected to the second flange through the first annular gasket, the annular partition and the second annular gasket. The first and second round foils are soldered into the apertures of the flanges, respectively, between which a cylindrical target with a diameter of less than 1 mm is installed, contacting with its ends with the concave surfaces of the dents facing each other in the centers of the first and second foils. The annular partition divides the cavity between the first and second flanges into inlet and outlet chambers, which are connected by cold pipes through cylindrical channels made in the first and second flanges, with the system of refrigerant circulation, control of its temperature and pressure. The third and fourth foils are soldered into the annular partition on both sides with central holes coaxial with the cylindrical target, the diameters of which are greater than the diameter of the cylindrical target. Behind the second flange there is a magnet, the interpolar space of which is located on the axis of the cylindrical target.

EFFECT: obtaining bremsstrahlung with a focal spot diameter less than 1 mm.
