Next Generation TOF Analyzer for Momentum Microscopy
The METIS 1000 is the next generation TOF spectrometer for ARPES and momentum microscopy. If a pulsed light source is available, the METIS 1000 is the intrument of choice. It allows aquisition of two in plane k-vectors against the kinetic electron energy in one shot. The lens system is optimized for high momentum resolution and aquired electrons from the complete half space above the sample, yielding ultimate acceptance angles. The lens design directly shows the k-space on the detector, hence, no conversion from angular space into real space is needed. Integrated deflectors in the microscopy lens allow to move the area of interest without moving the sample and integrated apertures can be used for µ-ARPES or contracst enhancement in PEEM.
The native repetition rate of the detector is 5-8 MHz. With a special frequency splitter is is possible to boost the acceptable repition rate up to 100 MHz.
