Fine Beam Tube with Connection Socket R

Product Overview

Experiment Topics: Deflection of electrons in a closed circular path inside a magnetic field. Determination of specific charge of an electron e/m. For examining the deflection of electron beams in a uniform magnetic field using a pair of Helmholtz coils (1000906) and for the quantitative determination of the specific charge of the electron e/m. Glass vessel with integrated electron beam system consisting of an indirectly heated oxide cathode a Wehnelt cylinder and a perforated anode in neon residual gas atmosphere with precisely set gas pressure and with integrated measurement marks for parallax free determination of the diameter of the fine beam. Gas atoms are ionized along the electron path and produce a sharply defined visible fluorescent beam. Tube mounted on base with colour coded connectors. Gas filling: Neon Gas pressure: 1.3x10 5 hPa Filament voltage: 5 ? 7 V DC Filament current: < 350 mA Wehnelt voltage: 0 ? 50 V Anode voltage: 200 ? 300 V Anode current: < 3 mA Circular path diameter: 20 ? 120 mm Division spacing: approx. 20 mm Tube diameter: approx. 160 mm Dimensions connection base: ? approx. 103 mm height: 78 mm Weight: approx. 820 g
