X-ray Source RS 40B1
High intensity twin anode Al/Mg source optimized for XPS and high pressure XPS experiments.
Manufacturer
Prevac
Prevac are a world leader in the design and production of analytical and deposit scientific and research equipment. Their systems operate in a high and ultra high vacuum environment. They design and construct UHV and HV systems fully adapted to the individual requirements of research projects and industrial applications.
Key Features
- High intensity twin anode Al / Mg
- Specially configured nose cone
- Very low cross-talk
- Low magnetic field
- Hermetically sealed housing
- Efficient 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
Description
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.
