THEMIS 1000 2D-DLD

Time-of-Flight Electron Energy Analyzer for ARPES and 2D DLD Detector and 1000 mm Drift Tube

The SPECS THEMIS is a time-of-flight analyzer, ideally suited for pulsed light sources with high repitition rates. The electron dispersion is done by the different travel time through the drift tube, when a bunch of electrons is emissted 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 repition rate is 5-8 MHz and an optional frequency entension to 50-80 MHz is available. 

The THEMIS 1000 comes with a 1000 mm drift tube. The lens system, beeing identical to the PHOIBOS 225, fits into a DN150CF flange.
