3B Scientific™ Fine Beam Tube T
Complete experimental system is used to determine electron's specific charge and investigate deflection of electron beams in uniform magnetic field.
Supplier: 3B Scientific™ U18575
Description
- Inside fine beam tube, sharply delimited electron beam is generated by system comprising indirectly heated oxide cathode, perforated anode and Wehnelt cylinder
- Impact ionization of helium atoms creates very bright, also sharply delimited trace of electron path in tube
- If tube is aligned optimally and an appropriate current flows through Helmholtz coils, electrons are deflected into circular orbit
- Diameter, anode voltage and magnetic field are parameters used to determine electron's specific charge
- Magnetic field can be calculated from coil current, geometry of Helmholtz coil pair being known
- Electron deflection in uniform magnetic field
- Closed orbit or spiral path
- Determining an electron's specific charge e/m
