Description :
Science Lab Supplies is a physics lab equipment manufacturer and exporter based in Jining City, Shandong Province, China, supplying the Fine Beam Tube (Neon-Filled) with Connector Base as part of our Atoms and Nuclei range for schools, colleges and STEM training institutes across China and worldwide.
The gas atoms are ionised along the path of the electrons and a narrow, well-defined, luminescent beam is produced. Incorporated measurement marks facilitate a parallax-free determination of the diameter of the circular path of the beam deflected in the magnetic field.
The Fine Beam Tube is used for investigating the deflection of cathode rays in a uniform magnetic field produced Science Lab Supplies by a pair of 300mm Helmholtz coils. In addition, it can also be used for quantitative determination of the specific charge of an electron e/m.
Located inside a glass bulb with a neon residual gas atmosphere is an electron gun, which consists of an indirectly heated oxide cathode, a Wehnelt cylinder and a perforated anode.
The protective circuit prevents excessive voltages from damaging the heater filament and ensures a "smooth" switch-on response once the voltage is applied. Requires a 0-300 V DC power supply and 300 mm Helmholtz coils.
The Fine Beam Tube Science Lab Supplies is mounted on a base with coloured connectors. In order to protect the tube, a protective circuit is built into the base, which shuts off any voltage in excess of the base's pre-set cut-off voltage.
