The continuous evolution of high-energy physics experiments is driving detector technologies towards increasingly stringent requirements on the precision of both spatial and temporal measurements. The simultaneous determination of a particle trajectory and its time coordinate is becoming a key element for precision tracking, event reconstruction, fast triggering, particle identification, and...

Since 1969, the Apollo and Lunokhod missions have deployed Laser Retroreflector Arrays (LRAs), consisting of Cube Corner Retroreflectors (CCRs), on the lunar surface. These devices reflect incident laser light back toward their source, enabling high-precision distance measurements through the technique of Lunar Laser Ranging (LLR). In LLR experiments, short laser pulses are transmitted from...

Free-electron lasers (FELs) probe matter at the sub-atomic scale through coherent pulses with sub-ångström wavelengths and sub-femtosecond durations, but the high-energy beams driving them have traditionally required large radio-frequency accelerators with a sizeable footprint. Plasma-based acceleration, with gradients up to three orders of magnitude higher, opens the way to far more compact...

Ultra-rare event searches in astroparticle physics require detectors capable of combining extreme sensitivity with long-term stability, background control, and precise calibration.
This presentation will focus on international experiments, including direct dark-matter searches, neutrinoless double-beta decay studies, neutrino telescopes, cosmic-ray and gamma-ray observatories, and...
