About This Product

■Purpose

・Deflection of electrons in a closed circular path in a magnetic field ・Determination of specific changes in electrons e/m

■Principle

- A narrow beam tube is used to investigate the deflection of cathode rays in a uniform magnetic field generated by a pair of Helmholtz coils (P338001). Additionally, it can be used to quantitatively measure the electron specific charge e/m. -The electron gun, located inside a glass bulb with a helium residual gas atmosphere, consists of an indirectly heated oxide cathode, a Wehnelt cylinder, and a perforated anode. Gas atoms are ionized along the path of the electrons, producing a narrow, well-defined beam of emission. Built-in measurement marks facilitate parallax-free measurements of the diameter of a circular path of a beam deflected within a magnetic field.
