Abstract: An x-ray detector can be small and have efficient cooling. In one embodiment, the x-ray detector can comprise a thermoelectric cooler (TEC) with upper electrical connections, a support, a cap, and a silicon drift detector (SDD). A planar side of the support can be directly affixed to upper electrical connections of the TEC. The support can have a non-planar side, opposite of the planar side, with a raised structure. A bottom face of the cap can be affixed to the raised structure, forming a cavity between the cap and the non-planar side of the support. The SDD can be affixed to a top face of the cap. In another embodiment, the non-planar side of the support can face the TEC. In another embodiment, a PIN photodiode can be directly affixed to a plate and the plate directly affixed to upper electrical connections of the TEC.

Abstract: A shield around an x-ray tube, a voltage multiplier, or both can improve the manufacturing process by allowing testing earlier in the process and by providing a holder for liquid potting material. The shield can also improve voltage standoff. A shielded x-ray tube can be electrically coupled to a shielded power supply.

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.

Abstract: In order to reduce the amount of electrical insulation needed for voltage isolation of large voltages generated by a voltage multiplier, the voltage multiplier can be shaped to smooth out electric field gradients. The voltage multiplier can comprise multiple sections, each section located in a different plane. The voltage multiplier can comprise a negative voltage multiplier and a positive voltage multiplier, each inclined at different angles with respect to each other. The voltage multiplier can include a curved shape.
