PHOIBOS 225 HV 2D-DLD

Ultra High Energy Hemispherical Energy Analyzer with 2D DLD Detector for HAXPES up to 15 keVwith 225 mm mean radius

The PHOIBOS 225 HV hemispherical energy analyzer is an ultra high kinetic energy analyzer solution for photoelectron spectroscopy on the material science edge. This analyzer can be operated in all relevant analysis modes, such as ARPES, XPS, UPS, as well as AES, ISS and LEISS. Its design and the modular supplementary hardware makes this analyzer the most versatile PES analyzer in the market. Its unique design allows stabe measurements up to 15 keV kinetic energy for highest XPS sensitivity in layered materials and deep core ESCA.

With a 2D DLD HV detector is shows outstanding performance in countrate, linearity and an ultrafast single event countingmechanism. It combines a state of the art lens system with a proven hemipshere design for highest transmission and kinetic energy stability. The analyzer can be operated in transmission (XPS/UPS), angular resolved (ARPES) and magnification mode (slab imaging).

The energy analyzer sectionis equipped with 8 customizable entrance and 3 exit slits. The analyzer comes with a special and highly stable power supply, the AVC 15000, for best performance in anb extreme kinetic energy range.

A classical CCD camera detection system is available on request.

HAXPES

Hard X-ray Photoelectron Spectroscopy can provide information about chemical composition in the bulk of a material, rather than in the surface.

ARPES

Angle-Resolved Photoelectron Spectroscopy detects the energy and angle distribution of photoelectrons to determine the electronic structure of solids.
