Matériel éducatif Matériel éducatif de physique Activités d'électricité/de magnétisme
Highly evacuated electron tube with focusing electron gun and fluorescent screen (90×60 mm) 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 an optional 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.

  • Max. anode voltage: 5000 V
  • Glass bulb diameter: approx. 130 mm

Informations de commande: Power supplies, connection leads and Helmholtz coil need to be ordered separately, please ask for details.
