Název v původním jazyce

Single photon detector operating under extremely high background photon flux conditions

Popis výsledku v původním jazyce

We are reporting our results in research and development in the field of avalanche semiconductor single photon detectors and their application. Our goal was a development of a solid state photon counting detector capable of high precision photon arrivaltime tagging in extremely harsh operating conditions. The background photon flux exceeding 109 photons per second hitting the detector active area should not avoid the useful signal detection and recognition on the signal level of units of photons per second. This is background photon flux about two orders of magnitude higher than the conventional solid state photon counters accept. The detection timing resolution should be better than hundred picoseconds, the delay stability should be on picosecond level. We have developed and tested the active quenched and gated avalanche structure on silicon providing the required features in connection with the K14 detection chips.
