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

FIELD: accelerator technology.

SUBSTANCE: invention relates to accelerator technology and can be used in the development of bremsstrahlung sources based on linear electron accelerators. The bremsstrahlung 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 an inlet chamber and an outlet chamber, which are connected by cold pipes through cylindrical channels made in the first and second flanges, with a refrigerant circulation system, its temperature and pressure control. A third foil with a hole whose diameter is greater than the diameter of the cylindrical target is soldered into the annular partition. 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.
