The PREVAC EA15-HP1 hemispherical energy analyser, which is based on the EA15 analyser, allows due to special designed extraction cones and automatic vacuum control, high-resolution PES measurements in static and dynamic environments up to 1 mbar.
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.
– 40 mm diameter dual MCP detector
– 656 energy channels available simultanously
– 494 angular channels available simultanously
– 90 fps
The analyser package includes:
EA15-HP1 hemispherical energy analyser can be controlled directly by LabVIEW programming environment.
