A convergent beam electron diffraction (CBED) technique has been described for the determination of the voltage of a transmission electron microscope (TEM). It involves observing the intersections of HOLZ lines (
), (
), (
) and (
), in the transmitted disc of the CBED pattern obtained along the [37 37 4] zone axis of silicon. It is suitable for the TEMs with operational voltage in the range of 200 kV, and is also free from the tilt limitations.
Keywords TEM, CBED, voltage, silicon
