PHOIBOS 150 with 2D-CMOS and 3D(2D) Spin Mott Detector

Hemispherical Energy Analyzer with 2D CMOS Detector for XPS, ARPES, ISS and LEISS and MOTT Detector for Spin Measurements with 150 mm Mean Radius

Spin detector for Hemispherical Energy Analyzer PHOIBOS 225 Mott MCD

The PHOIBOS 150 hemispherical energy analyzer is the-state-of-the-art 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.

The patented design of the detector section allows measurements of all three spin components and subsequent 2D ARPES merasurements. The 2D detector is a full scale 2D CMOS detector un undiminished performance in standard PES. The spin channel consist of a 90° deflector to acess the out of plan spin component and a special rotator lens to swich between the two in plance components of the spin. 

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).

The 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 1.8 meV. The analyzer comes with a highly stable power supply, the HSA 3500 plus, for best performance in a wide kinetic energy range.

A classical CCD camera detection system is available on request.
