Compact, all-in-one apparatus in light-tight enclosure to study the motion of electrons under the influence of electric and magnetic fields and determine their charge-to-mass ratio.
Overview
Compact, all-in-one apparatus in light-tight enclosure to study the motion of electrons under the influence of electric and magnetic fields and determine their charge-to-mass ratio. Instructional manual with historical background, relevant web links and sample data with analysis included. Arbor Scientific teaching consultants are available by appointment for questions and technical advice.
Features and Specs
Fine Beam Tube: A low-pressure 16-cm diameter inert gas-filled tube is mounted vertically and can rotate 180 degrees for fine adjustment of the horizontally-projected electron beam and observation of spiral orbits.
Light-tight enclosure: The entire apparatus is in a light-tight enclosure, very convenient for operating in normal lighting conditions.
Built-in Digital Voltage Supply: Sets of accelerating and deflecting electrodes have built-in voltage supplies with digital readouts.
Built-in Digital Current Supply: A pair of permanently-mounted Helmholtz coils has built-in variable current power supply with digital readout.
Measurement Aides: Metric scale and viewing aides to accurately determine the electron-orbit radius are included.
