MTS 723 XPS 2 Source parameters for XPS. Source Type The choice of anode material, such as Mg, Al, . ... Source Power The operational current and voltage of the source. Two equivalent ways of choosing this are source voltage + source power or source voltage + filament emission current We typically have to outgas and recondition the x-ray source after venting the system to air and baking out.

MTS 723 AES Source parameters for AES. 3 Source Voltage The beam voltage of the source (typically in keV). Emission Current The operational emission current from the source. Beam Position and Size We usually have the ability to control where the beam hits the sample and how big the spot is at the same through control of the deflection and focussing lenses. Changing the beam voltage may defocus or move the spot at the sample.
