SOFT X-RAY SOURCE BASED ON DEMOUNTABLE X-RAY TUBE Russian patent published in 2014 - IPC H01J35/02 H05G2/00 

FIELD: physics.

SUBSTANCE: source includes a housing to which a base is attached, said base having an anode and a hot-cathode assembly with electrodes and an incandescent filament, high-voltage and low-voltage leads for connecting to power supplies, as well as a focusing electrode and a cooling system. The cooling system is in form of a pipe loop which is electrically connected to the high-voltage lead. The anode is solid, has the shape of a parallelepiped and is mounted directly on the pipe by fastening elements. The hot-cathode assembly is provided with an elastically deformable component which is mounted by one end on one of the electrodes of the hot-cathode assembly and is connected to the incandescent filament through a force connection, while allowing movement of the free end and tightening of the incandescent filament as it heats up when voltage is applied. The focusing electrode is in form of a component which partially encircles the incandescent filament.

EFFECT: simple design and ensuring stable radiation parameters.
