Classification: CPC G  H | IPC G  H

Claim 8:
9. A method for calibrating the beam injector of claim 1, comprising:
operating the beam injector to cause the heater to heat the cathode emitter to cause the cathode emitter to emit electrons, wherein the resistor has an initial resistor value;
increasing a current supplied to the heater until saturation is reached; and
determining if an electron beam current is at a pre-determined value, wherein:
when the electron beam current is at the pre-determined value, the beam injector is operated when desired, and
when the electron beam current is not at the pre-determined value, the initial resistor value is changed to a second resistor value.
