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.
