Next Generation TOF Analyzer for Momentum Microscopy
The METIS 1000 is the next generation TOF spectrometer fror ARPES and momentum microscopy. If a pules light source is available, the METIS 1000 is the intrument of choise. 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 jhalf 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 aear of interest without moving the sample and integrated apertures can be used for µ-ARPES or contracst enhancement in PEEM.
The native repition rate of the detector is 5-8 MHz. With a special frquency splitter is is possible to boost the acceptable repition rate up to 100 MHz.
