Description Teltron Discharge TubesThe Teltron range of demonstration discharge tubeshas been designed to show the properties of the freeelectron.The D range is the original Teltron range with connectionsfixed on the tubes. The S range is a newer range withconnections on the stand rather than the tubes.Please note the ranges are not interchangeable.Teltron Dual Beam Tube DSemi-evacuated electron tube filled with low-pressurehelium and containing a tangential and axial electrongun. In the case of tangential bombardment and a perpendicularly aligned magnetic field, the fundamentalelectron charge-to-mass ratio can be determined fromthe diameter of the observed beam pattern. In the caseof axial bombardment and a co-axial magnetic field,kinetic gas theory (e.g. impact excitation) and particlecollisions can be studied through observations of thefine, luminescent beams resulting from excitation of thehelium atoms. Product includes tube only. Instructions included.Other equipment for use with the Teltron tubes:605-006 EHT Power Supply261-031 Digital Meter with two shunts included ( 261-014 )
