Thomson presenterade sina resultat 1897 och gav det nya materietillståndet namnet elektron. J.J. Thomsons experiment.

Thomson repeated Hertz's experiment with a better vacuum in 1897. He directed the cathode rays between two parallel aluminum plates to the end of a tube 

In his seminal paper,  We present a new model, and the validating experiments, that unveil the rich physics behind the flight of a conductive ring in the Thomson experiment, a physics  In this lab you will essentially repeat Thomson's experiment and measure e/m for electrons.

Falconer, Theory and experiment in J.J. Thomson's work on gaseous  Yet this experiment was performed two months after Thomson first announced that cathode rays were very small, negatively charged particles.

J. J. Thomson (1856-1940) Cathode Rays Philosophical Magazine, 44, 293 (1897).[facsimile from Stephen Wright, Classical Scientific Papers, Physics (Mills and Boon, 1964).] The experiments* discussed in this paper were undertaken in the hope of gaining some information as to the nature of the Cathode Rays. The most diverse opinions are held as to these rays; according to the almost unanimous Thomson finds the charge to mass ratio of a cathode ray particle. Thomson wanted to know two things.

1 Apr 2014 In 1906, Thomson began studying positively charged ions, or positive rays. This led to one of his other famous discoveries in 1912 when he

In Thomson’s experiment, a fluorescent material was coated on the end of the tube to produce a glowing dot where the cathode rays hit. You can see a simulation of this glow on the far right of the applet diagram, as shown in Figure 2. Thomson measured the deflection of the beam using a … Thomson therefore suggested that atoms are spheres of positive charge in which light, negatively charged electrons are embedded, much as raisins might be embedded in the surface of a pudding. At the time Thomson proposed this model, evidence for the existence of positively charged particles was available from cathode-ray tube experiments.
