Electron multiplier

Floating output remote control voltage monitor low ripple high stablity

Electron multiplier is mainly based on photoelectric effect and secondary electron emission. When a beam of light falls on the cathode, it produces photoelectrons. These photoelectrons are accelerated by a high voltage electrostatic field and hit the channel wall of the multiplier. During the collision, the channel wall material releases more electrons, which is called secondary electron emission. This process is repeated many times, each time multiplying the number of electrons. Finally, after several times of multiplication, the output of the electrical signal amplitude and the energy of the incident particles proportional to achieve the amplification of the signal.
