Abstract: In one embodiment, an x-ray tube 15 can be used closer to a sample. An angle A1 between an anode axis 02 and an electron-beam axis 01 can be ≥10° and ≤80° and an angle A2 between the anode axis 02 and an x-ray axis 03 can be ≥10° and ≤80°. In another embodiment, a cap 20 on an anode 12 can block x-rays emitted in undesired directions. The cap 20 can include an internal cavity 24, an electron-beam hole 21, an anode hole 22, and an x-ray hole 23. In another embodiment, an electrical connection between an x-ray tube 15 and a power supply 18 can be reliable and easy to manufacture. The anode 12 can include a hole 31 at an end of the anode 12 sized and shaped for insertion of an electrical connector 32.

Abstract: An x-ray source can include a housing with material with an atomic number of ≥42 and a thermal conductivity of ≥3 W/(m*K) to assist in removing heat from the x-ray source and to block x-rays emitted in undesirable directions. An x-ray source can include a shell that is electrically conductive and that encloses at least part of a voltage multiplier without enclosing a control circuit to minimize or eliminate electromagnetic interference in the control circuitry caused by the voltage multiplier. An x-ray source can include a negative voltage multiplier, a positive voltage multiplier, and a ground plane between the negative voltage multiplier and the positive voltage multiplier. The ground plane can minimize or eliminate electromagnetic interference between the negative voltage multiplier and the positive voltage multiplier. An air-filled channel, associated with the ground plane, can reduce weight of the x-ray source.
