1. An x-ray source comprising:
an x-ray tube electrically-coupled to a power supply;
the power supply includes multiple stages, in a stack, configured to multiply an input voltage to provide a larger output bias voltage;
each stage (a) includes electronic components on a top-side of a circuit board, (b) has an input and an output, and (c) is configured to increase voltage from the input to the output;
the circuit board for each stage is separate from the circuit boards of other stages in the stack;
the output of each stage, except for a highest-voltage-stage, is electrically coupled to the input of a higher voltage stage;
the input of each stage, except for a lowest-voltage-stage, is electrically coupled to the output of a lower voltage stage;
in each stage the electronic components are directly soldered to the top-side of the circuit board for that stage; and
in each stage, except for the highest-voltage-stage, the electronic components are directly soldered to a bottom-side of the circuit board of the higher voltage stage, the bottom-side of each circuit board being opposite of the top-side.
