XR 50

The XR 50 is a high intensity dual anode X-ray source for XPS applications. The electron optical design of the anode, filament and source housing guarantees maximum X-ray intensity and very low crosstalk between the anode faces.

The XR 50 is a high intensity twin anode X-ray source optimized for XPS experiments. The anode is made of silver to avoid any CuLα breakthrough. Due to the use of dual anodes it is possible to switch between two different incident energies without the need to vent the system. Dual anodes with different material coatings are available on request. The electron optical design of the anode, filament and source housing guarantees maximum X-ray intensity and very low crosstalk between the anode faces.

A specially configured nose cone allows maximum access to the sample. A thin aluminium foil window over the end of the x-ray allows the source to be differentially pumped if required. In addition to the anode, the anode housing is as well very efficiently water-cooled in order to reduce the damage of the sample by thermal effects during operation. Even during longterm operation the sample temperature is not increased by more than 5 °C.
