Flares and their echoes can help distinguish photon rings from black holes with space-Earth very long baseline interferometry

A. Andrianov, S. Chernov, I. Girin +3

Photon rings near the edge of a black hole shadow is supposed to be a unique tool to validate general relativity and provide reliable measurements of principal black hole parameter…

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…

Narrow-Band Pulsed Electron Source Based on Near-Threshold Photoionization of Cs in a Magneto-Optical Trap

O. Fedchenko, S. Chernov, G. Schönhense +2

The newly developed method of time-of-flight (ToF) momentum microscopy was used to analyse the cold electron emission from a Cs 3D magneto-optical trap (MOT). Three-step resonant p…

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…
