Ion Source IS 40E1

Ion Source IS 40E1 – two lens, extractor type, focused. Suitable for depth profiling (Ar), enables operation with reactive gases like O2, H2, hydrocarbons and all noble gases.



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

  • Specially configured nose cone
  • Operation with inert (Ar) & reactive gases (O2, H2, hydrocarbons with reduced lifetime)
  • Continuously variable spot sized
  • Extremely homogeneous crater/beam profile
  • Onside replaceable filament
  • UHV gas inlet
  • UHV conditions maintained in chamber
  • Integrated scan and deflection unit
  • Correction of incident electron beam angle (provided by IS40-PS power supply)


The source is able to raster a 10 mm x 10 mm area of the surface at the recommended working distance. It is particularly suitable for depth profiling in XPS, ISS and SIMS. The source can be also used for sample surface cleaning.
