2. RF timer and RF timer-based electron, photon, and heavy ion sensors

We propose a new radio frequency timer of keV energy electrons. By converting a time distribution of incident electrons to a hit position distribution on a circle, ellipse or spiral, by means of the radio frequency fields laying in the range 500-1000 MHz, this device achieves extremely precise timing. Streak Cameras, based on similar principles, routinely operate in the ps and sub-ps time...

13. TRD based on highly segmented solid state detectors

TRDs are commonly used in PID applications, exploiting the threshold Lorentz factor for TR emission. Since TR X-rays have energies from a few keV to a few tens of keV, TRDs are usually equipped with gaseous detectors.

Recently, new techniques for measuring the TR with solid state detectors have been successfully implemented. High-granularity semiconductor pixel or microstrip detectors...

11. Direct detection of charged particles with SiPMs

Recent studies demonstrated that SiPMs are highly suited in directly detecting charged particles(ref.1-2).The reason is traced back to the abundant production of Cherenkov photons when a MIP passes through the SiPM's protection layer.This leads to a significant increase in the firing SPADs number,resulting in:
1. efficiency close to 100%
2. excellent timing performance, reaching 20-30 ps...
