Several surface potential control methods were evaluated with a focusing monochromatic X-ray photoelectron spectroscopic measurement for a silica glass. Distortion of the O1s signal was easily improved by the combination of a low energy electron flood gun and an electrically grounded Ni mesh screen mounted about 1 mm above the sample surface. It was also found that the potential could be controlled by the combination of Ar gas introduced into vacuum chamber and an ion gun with no accelarating bias.
