The hemispherical energy analyser is intended to provide high-resolution PES measurements to be analysed in a 150 mm mean radius assembly.
The analyser is wrapped in a shield constructed of 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 8 predefined PE to satisfy customer's requirements.

The ES 40C1 Electron Source is a scanable electron gun with small spot profile. Due to the high transmission of its Einzel-Lens, the ES 40C delivers a high electron beam current over a wide energy range. The ES 40C1 is designed for a stable and reliable operation in e.g. AES, scanning applications,imaging, EELS and electron pulse or desorption experiments.
