THEMIS 600 2D-DLD
Time-of-Flight Electron Energy Analyzer for ARPES and 2D DLD Detector and 600 mm Drift Tube
The SPECS THEMIS is a time-of-flight analyzer, ideally suited for pulsed light sources with high repetition rates. The electron dispersion is done by the different travel time through the drift tube, when a bunch of electrons is emitted from a short laser pulse. Depending on the kinetic energy window, an ultra high resolution in the sub-meV range can be detected.
The detection system is the 2D DLD detector with x and y detection for angular resolved data and integrated 240 ps time resolution. The native repetition rate is 5-8 MHz and an optional frequency extension to 50-80 MHz is available.
The THEMIS 600 comes with a 600 mm drift tube. The lens system, being identical to the PHOIBOS 100/150 fits into a DN100CF flange.
