Apparatus for measuring the velocity of the cathode rays and the ratio of the mass of the carriers to the charge carried by them. (J.J. Thomson's original e/m cathode ray tube.)

This is one of the original vacuum tubes used by the Cambridge professor of physics John Joseph Thomson to discover the electron in 1897. Thomson's work contributed enormously to our understanding of the atomic structure of matter, leading to the research fields of atomic and nuclear physics, and marking the birth of the modern electronic age. An enthusiastic and ambitious theoretician, Thomson was known to be an inexpert experimenter. But the results of his work with simple table top apparatus have proved momentous.
