, but with a voltage jump of +800 V. The piezo creep-compensation voltages were simply 1.6 (800/500) times greater in amplitude than the +500 V tests. This confirms that the compensation voltages are proportional to the main voltage jump, which makes it very easy to pre-calculate the compensation voltages required for any permissible change in X-ray beam size.
