DESCRIPTION

The RS 40B1 X-ray Source is a high intensity twin anode Al/Mg source optimized for XPS and high pressure XPS experiments (option). 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. Twin anode used in standard source, allows for separated emission of two different characteristic X-radiation emission lines: Mg (1253 eV), Al (1487 eV) – other coating materials on request.

FEATURES

• High intensity twin anode Al / Mg
• Specially configured nose cone
• Very low cross-talk
• Low magnetic field
• Hermetically sealed housing
• Very efficiently water-cooled inner housing in order to reduce thermal damage to the sample during operation
• In-built double high voltage protection together with hermetically sealed housing
• Able to work in high pressure experiments in the mbar range (option)
• Able to work under full control with limited water flow.

OPTIONS

• High Pressure version, up to 5 mbar (20 mbar in development)
• Linear shift with tilt 50 – 100 mm (for HP X-ray source equipped with additional pumping port)
• Chiller
