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.

Miniature X-ray source insulation structure, said X-ray source comprising a high voltage anode (10) and a cathode (12) disposed in said insulation structure (7,30), characterized in that said insulation structure comprising a first layer (7,32) having a low gas permeability, and a second layer (30) having a high electrical break-through voltage, such that the insulation structure achieves predetermined requirements with regard to electrical break-through voltage and gas permeability.
Miniature X-ray source comprising an insulation structure defining a cavity (8) where an anode (10) and a cathode (12) are arranged, said cavity being evacuated, connecting means (14,16) arranged to connect the anode and the cathode to a high voltage source in order to energise the X-ray source, characterized in that the insulation structure includes a first layer (7,32) and a second layer (30), 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, wherein the electrical break-through voltage for the insulation structure is above a predetermined threshold value.
