Fluorescent screen deflection cathode ray Crookes Tube vacuum USSR antique rare
A tube for demonstrating the deflection of cathode rays by a magnetic field. Made in the USSR at the Leningrad plant Elektrodelo in 1950. Crookes placed a magnet on the tube with the north pole on one side of the beam and the south pole on the other, and the beam would pass through the magnetic field between them. The beam was bent perpendicular to the magnetic field. To show the path of the beam, Crookes invented a tube with a phosphor screen over the entire length of the tube at a slight angle that electrons hit the phosphor along its length, forming a luminous line on the screen. The line was seen to bend up or down in a transverse magnetic field.
Both electric and magnetic deflection were proof of particle theory because electric and magnetic fields do not affect the beam of light waves.
