KSCI-FBTC Klinger Scientific Fine Beam Tube Complete Experiment

Klinger Scientific Fine Beam Tube Complete Experiment Objectives:Deflection of electrons in a closed circular path inside a magnetic fieldDetermination of specific change of an electron e/mClosed orbit or spiral path Principles:The fine beam tube is used for investigating the deflection of cathode rays in a uniform magnetic field produced by a pair of Helmholtz coils (KSCI-HCL). 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 helium residual gas atmosphere is an electron gun, which consists of an indirectly heated oxide cathode, a Wehnelt cylinder and a perforated anode. The gas atoms are ionized 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.
