Leybold Fine Beam Tube with PHYWE High Voltage Power Supply and Helmholtz Coils:

"A fine beam tube consists of a spherical glass plunger filled withnoble gas under low pressure.An electron gun inside the tube(cathode, control grid and anode) generates a beam of electrons.The beam stimulates gas molecules to the emission of light,whereby the beam becomes visible within the tube.The magneticfield of two Helmholtz coils forces the electrons onto a circular paththat allows us to determine the specific charge e/m."source
Become a scientist and experiment with electrons in magnetic field! Hands-on fundamental physics used in CRT TVs and particle accelerators! Better than Tesla coils!
Great opportunity - ready-to-work set is really hard to get these days!


Video below shows the device I'm selling operating!

The set comprises of:

1. Leybold Heraeus Fine Beam Tube (good working condition)

2. PHYWE 0-600V Regulated Power Supply (good working condition)

3. set of safety 4mm banana plug connectors

important: the red unit pictured does NOT come together with above listed. It was used to supply higher current to Helmholtz coils (up to 3A) rather than 0.5A allowed by PHYWE Supply, which allows higher curvature of the electron beam and better overall effect. There is no need for it to conduct the experiment-the PHYWE Power Supply has output to power the coils, and if need for higher current arrises, it can be easily replaced by most bench Power Supplies. If you still wish to receive the red unit, please contact me first.


Pictures show electron beam in magnetic field of varying magnitude. The glow, being faint, is best visible in darkness, but not exclusively, as seen on one of the photographs.
