PREVAC EA15 hemispherical energy analyser provides high-resolution PES measurements with a 150 mm mean radius analyser.
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.
– 40 mm diameter dual MCP detector
– 656 energy channels available simultanously
– 494 angular channels available simultanously
– 90 fps
The analyser package includes:
EA15 hemispherical energy analyser can be controlled directly by LabVIEW programming environment.
