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 using two methods: 1) electrically using electric field of the built-in plate capacitor, or 2) magnetically using external Helmholtz Coils D (U191051). Also determine the fundamental electron charge-to-mass ratio (e/m) and study mean electron velocities using field cancellation.
Universal power supply with digital current and voltage display.
Universally applicable, floating, high-voltage power supply with
Pair of Helmholtz coils for generating a uniform magnetic field perpendicular to the axis of the Teltron D series tubes.
Tube holder made of robust plastic for holding D-series electron tubes. Stand has a wishbone, 360° rotating clamp made of heat-resistant plastic and two base holes for affixing the Teltron Helmholtz Coils D (U191051). On rubber feet to prevent slipping ...
