Description
Electron tube mounted on terminal base for investigating the design and operation of modern cathode ray tubes. The electron beam can be deflected by an electric field produced by the deflection plates integrated into the tube, and by a magnetic field from three external coils mounted on a ring. A Wehnelt cylinder is used to focus the beam. A gas filling and fluorescent screen makes it possible to observe the beam in the tube. A continuously adjustable saw-tooth generator can be used to analyze and visualize time dependent processes. The device comes with a socket and printed wiring scheme. Anode voltage: 250-400 VDC. Anode current: 1 milliampere. Filament voltage: 6 - 8 volts AC/DC. Filament current: 0.3 A. Wehnelt voltage: 0 - 50 VDC. Deflection plate dimensions: approximate 12 x 20 cubic millimeters. Plate spacing: approximate 12 mm. Electric deflection sensitivity: 0.2 mm/V. Screen diameter: approximate 100 mm. Tube length: approximate 260 mm. Residual gas: Neon. Gas pressure: 10-4 hectopascals. Sweep frequency: 10 to 200 Hertz, continuously adjustable. 3 deflection coils: 600 turns each, with a centre pickup. Weight: approximate 1.6 kilograms.
