Time-of-Flight Photoelectron Momentum Microscopy at 100-500 MHz Synchrotron Sources: Electron-Optical Chopping or Bandwidth Pre-Selection
G. Schoenhense, K. Medjanik, O. Fedchenko +10
The small time gap of synchrotron radiation in conventional multi-bunch mode (100-500MHz) is prohibitive for time-of-flight (ToF) based electron spectroscopy. Even the new generati…

Breakthrough in HAXPES Performance Combining Full-Field k-Imaging with Time-of-Flight Recording
K. Medjanik, S. V. Babenkov, S. Chernov +8
We established a new approach to hard-X-ray photoelectron spectroscopy (HAXPES). The instrumental key feature is an increase of the dimensionality of the recording scheme from 2D t…
