Hemispherical Energy Analyser EA15-HP50

The EA15-HP50 allows high-resolution PES measurements in static and dynamic environments up to 50 mbar.



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

  • EA15 150 mm hemispherical energy analyser
  • RUDI-EA2 high stable and low noise electronics
  • SPECTRIUM acquisition and analyser control software for Windows OS computer system


The analyser is equipped with a total number of 11 slits and offers the possibility to choose between best energy resolution and best intensity. According to given photoelectron energy, the analyser is set up with up to 9 predefined PE to satisfy customer’s requirements.

EA15 hemispherical energy analyser can be controlled directly by LabVIEW programming environment.

Note: The use of a mu-metal analysis vacuum chamber or an inner mu-metal shielded chamber in combination with PREVAC EA15-HP50 hemispherical energy analyser is recommended in order to minimalise influence of external magnetic fields and to maximise performance of the analyser.
