The 525 Deflection e/m Tube is the same tube we have offered for more than 30 years. It is offered primarily for departments that have a pre-existing collection of tubes and bases, and would like a replacement tube. Both the 525 and the 2525 are built to the same high standards and will serve as a valuable educational tool for years to come.

The 525 Deflection e/m Tube is the same tube we have offered for more than 30 years.

Highly evacuated electron tube with focusing electron gun and fluorescent screen inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using the Helmholtz coil pair D. By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge e/m and the velocity of the electrons.
