In fact, today photon detectors (or photodetectors) are omniprsesent. Indeed, look around yourself and you will encounter with photon detectors everywhere and at any time of the day or night. Nature created a great variety of photon detectors for living creatures from primitive, simplest photosensors to the most sophisticated ones. Charles Darwin considered human eyes as a pinnacle of Evolution, but he did not know mantis shripm eye system yet! Photon detectors are «workhorses» of physics experiments starting from ancient observations and Galileo`s telescope to nowadays neutrino telescopes, from the simplest detectors for street lights switching or car parking systems to the complex sophisticated CCD/CMOS cameras of astronomical telescopes (VLT, Hubble, Webb etc.), PET-cameras, etc.
In this talk we will cover evolution ideas in photon detection, vacuum photomultipliers in particular, for physics experiments. Following Murray Gell-Mann`s famous book, we will dare to show human mind endeavours in the developments of photon detectors «in the Simple and the Complex».
About the speaker:
Prof. Bayarto from Institute for Nuclear Research of the Russian Academy of Sciences in Moscow, Russia. His research field of interest is experimental physics covering neutrino physics, cosmic ray physics, ground-based gamma-astronomy, axion physics etc. His special interest is focused on the development of experimental techniques, photon detectors in particular. He has been participating in a number of experiments including the pioneering deep underwater neutrino telescope at Lake Baikal, the cosmic ray and gamma-astronomy experiment TAIGA, the GERDA neutrinoless double-beta decay experiment, the TA experiment, the JUNO experiment, the LEGEND experiment, the IAXO experiment etc.
