Recording of sequential single photons counted by way of recording and counting sequential
electron pulses at the anode
of the photomultiplier.
- Each electron pulse consists of 105–106
electrons resulting from the multiplication, in the 'dynode' arrangement
(or the microchannel plate) of a photomultiplier, of a single photoelectron
emitted by a photosensitive layer (the photocathode of the photomultiplier)
upon arrival of a single photon.
- Technique used for two purposes: (i) sensitive measurement of low levels
of radiation such as those originating from a luminophore and
(ii) recording of emission decays.
