Pump-probe experiments at Free-Electron Laser facilities depend heavily on the relative timing precision of the pump and the probe, which determines the resolution of the observed ultrafast phenomena. The DESY's Bunch Arrival Time Monitors (BAM) are state-of-the-art sensors based on an electro-optical detection principle, that delivers information on the bunch timing with unprecedented...
The successful laser cooling of positronium (Ps) via the 1$^3$S – 2$^3$P transition using broadband laser pulses, recognized as a Physics World Top 10 breakthrough in 2024, marked a milestone in antimatter research. Ps, a bound state of a positron and electron, posed significant challenges due to its 142 ns lifetime and broad Doppler profile. Achieved by the AEgIS collaboration at CERN, this...
