FIELD: physics.
SUBSTANCE: pulsed X-ray tube has a housing in form of a cylindrical cup made from high-thermal conductivity metal, a metallic window for outlet of X-ray radiation in form of a spherical segment or a hemisphere, the edge of which encircles the bottom of the cylindrical cup. There is target made from material with high atomic number and an insulating element with a cathode at the bottom inside the cylindrical cup. A substrate is further formed under the target, said substrate being made from refractory material and having thermal contact with the cylindrical cup formed through a silver soldered joint.
EFFECT: invention enables to make a pulsed X-ray tube with high durability and which operates with X-ray radiation with quantum energy higher than 200 keV.
