Electron beam tube
WebThe main elements of a traveling-wave tube (TWT) are (1) an electron gun, (2) a focusing structure that keeps the electrons in a linear path, (3) an RF circuit that causes RF fields to interact with the electron beam, and (4) a … WebThe electron starts from rest (near enough) so the kinetic energy gained is given by ½ mv 2 where m is its mass and v is its speed. So we can say that: ½ mv 2 = eV. The mass of the electron is m = 9 × 10-31 kg. The electronic charge is e = 1.6 × 10-19 C. For an electron gun with a voltage between its cathode and anode of V = 100V the ...

Premium Franck-Hertz Experiment Power Supply ... WebThis is an example of the motor effect. The electron beam represents an electric current (in the opposite direction to the beam, since the electron charge is negative). Fleming’s left-hand rule will give the direction of the force on the electrons. You could use Helmholtz coils to produce a uniform and calculable field in the evacuated tube.
