Electron Deflection Tube D
For investigating electron beams in electric and magnetic fields and determining specific charge e/m through compensation of magnetic deflection by electrostatic deflection. Also for estimating the speed of electrons.The integrated plate capacitor allows electron beams to be deflected electrostatically and – by using a set of demonstration Helmholtz coils (U19105) – magnetically. The path taken by the electron beams is rendered visible on a fluorescent screen with a centimeter grid inclined by 15° with respect to the beam axis. Equipped with an integrated focusing electrode system.
