Fine Beam Tube *BEST SELLER* Hot cathode ray tube with indirectly heate oxide cathode, Wehnelt cylinder and conical anode with a screening cylinder, as well as a pair of plates for electrostatic deflection of the beam. Hydrogen filling with precisely adjusted pressure in which the path of electron beams can be seen in the form of a luminous, sharply defined bundle of ions. Designed for qualitative and quantitative investigations of electron beams in electric and magnetic fields as well as for the determination of the charge-to-mass ratio e/m of the electron and also for measuring the electron velocity v. Technical Data: Gas filling: hydrogen 1.33 x 10-5 bars Electrode system: indirectly heated oxide cathode, Wehnelt cylinder, conically shaped anode with semi-cylindrical screen Filament voltage and current: 6 V, 1 A approx Anode voltage: 150 V DC to 300 V DC Wehnelt voltage: 10 V max. Deflection: pair of deflection plates for electrostatic deflection Connecting socket with nine pole pin-socket (555 581) Deflection voltage: 50 V DC to 100 V DC Dimensions: Diameter of glass bulb: 17.5 cm Overall length: approx. 35 cm INSTRUCTIONS FOR USE PLEASE CLICK HERE
