1. An x-ray source comprising:

  • a. an electrically insulative cylinder;

    b. an x-ray tube comprising;

    i. an evacuated chamber;

    ii. an anode disposed at one end of the evacuated chamber;

    iii. a cathode disposed at an opposite end of the evacuated chamber from the anode;

    c. the electrically insulative cylinder circumscribing a portion of the evacuated chamber;

    d. a first resistor and a second resistor electrically connected in series;

    e. the first resistor;

    i. comprising a line of electrically insulative dielectric ink painted on a surface of the electrically insulative cylinder;

    ii. having a resistance of at least 10 mega ohms;

    iii. including a first end attached to either the anode or the cathode; and

    iv. including a second end electrically connected to a first end of the second resistor;

    f. a resistance of the first resistor is at least 100 times higher than a resistance of the second resistor; and

    g. a voltage measurement device connected across the second resistor and configured to measure a voltage across the second resistor.
