EXPERIMENT 11 Determination of e/m for the Electron Introduction
... The ratio of charge to mass, e/m, is a fundamental property of the electron. In the present experiment it is determined by measuring the deflection of a beam of electrons in electric and magnetic fields. The apparatus (Fig. 11.1) consists of a large vacuum tube supported at the centre of a pair of H ...
