A dynode is an electrode in a vacuum tube that serves as an electron multiplier through secondary emission. The first tube to incorporate a dynode was...

electron hits a dynode inside a vacuum chamber and ejects electrons that cascade onto more dynodes and repeats the process over again. The dynodes are set up...

light by as much as 100 million times or 108 (i.e., 160 dB), in multiple dynode stages, enabling (for example) individual photons to be detected when the...

photocathode and accelerated towards a polished metal electrode (called a dynode). They hit the electrode surface with sufficient energy to release a number...

strike the second dynode. Each subsequent dynode impact releases further electrons, and so there is a current amplifying effect at each dynode stage. Each stage...

A continuous dynode particle multiplier detector...

anode known as a dynode causing more electrons to be released from that dynode. Those electrons are accelerated toward another dynode at a higher voltage...

photocathode that emits electrons when illuminated, followed by a series of dynodes that multiply the electron current through secondary emission. PMTs offer...

field across the MCP, each individual microchannel becomes a continuous-dynode electron multiplier. A particle or photon that enters one of the channels...

photocathode readily releases electrons. By means of a series of electrodes (dynodes) at ever-higher potentials, these electrons are accelerated and substantially...

These photons are then detected by the photomultiplier tube. A conversion dynode, such as a microchannel plate can also be used between the ion beam and...

September 1928. The introduction of a multipactor in October 1933 and a multi-dynode "electron multiplier" in 1937 made Farnsworth's image dissector the first...

a fast secondary emission multiplier (SEM) where first converter plate (dynode) is flat. The electrical signal from the detector is recorded by means of...

Ag-Mg-O-Cs dynodes, diheptal (14-pin) base XP1001 – 10-stage photomultiplier for gamma ray scintillation spectrometry, Sb-Cs cathode, Ag-Mg-O-Cs dynodes XP1002...

photomultipliers; a photocathode converts the light into electrons; and then by using dynodes to generate electron cascades through delta ray production, the signal...

trapping field for detection. Ions are accelerated into two high voltage dynodes where ions produce secondary electrons. This signal is subsequently amplified...
