Spin detector for Hemispherical Energy Analyzer PHOIBOS 225 Mott MCD

The PHOIBOS 225 hemispherical energy analyzer is ultra high resolution analysis solution for photoelectron spectroscopy. 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.

Combined MCD Spin Detector

The electron detector combines a classical multi channeltron detector with 6 channels and a spin detection channel for subsequent XPS/UPS and Spin measurements. The actual spin detector is based on the Rice University mini MOTT scheme, where a thin tungesten target on high voltage (25 kV) is used as a spin selective scattering target. With the MOTT detector it is possible to measure 4 channels in one experminet (two spin components with spin up/down, respectively).

Hemispherical Energy Analyzer and Power Supply

The hemispherical energy analyzer sectionis equipped with 8 customizable entrance and 3 exit slits. For highest energy resolution the entrance slit can be chosen down to 50 µm, providing achievable energy resolution better than 1 meV (with a 2D detector). The analyzer comes with a highly stable power supply, the HSA 3500 plus, for best performance in a wide kinetic energy range.
