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

  • Computer set
  • 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

Description

The analyser is wrapped in a shield constructed of up to two parallel mu-metal plates guaranteeing adequate analysis conditions for low-and high-energy photoelectrons.

Equipped with a total number of 11 slits, the analyser 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 8 predefined PE to satisfy customer’s requirements.
