Abstract: An X-ray tube 1 includes spacer 8 which is cylindrical so it does not block electrons 80 directed from a grid electrode 72 toward a focusing electrode 25, and which has one end 8b fixed to the grid electrode 72 and the other end 8c abutting against the focusing electrode 25. The distance between the grid electrode 72 and focusing electrode 25 is set to a predetermined distance by the spacer 8.

Abstract: An apparatus for generating x-rays has a structural unit which contains an x-ray tube, a digital control, regulation and storage unit for operating the x-ray tube, and all other components associated with, and supporting, operation of the x-ray tube. All of the components in the structural unit are connected to the digital control, regulation and storage unit. The apparatus also includes a peripheral device having a process computer. The digital control, regulation and storage unit has an interface to the process computer, which forms a single interface to the process computer for all of the components of the structural unit.

Abstract: Miniature X-ray source comprising an insulation structure defining a cavity where an anode and a cathode are arranged, said cavity being evacuated, connecting means arranged to connect the anode and the cathode to a high voltage source in order to energise the X-ray source. The insulation structure includes a first layer and a second layer, the first layer facing the cavity and has a low gas permeability, and the second layer is arranged outside said first layer and has a high electrical break-through voltage. The electrical break-through voltage for the insulation structure is above a predetermined threshold value.
