In 1886 he discovered what he termed Kanalstrahlen, or canal rays, also called positive rays; these are positively charged ions that are accelerated toward and through a perforated cathode in an evacuated tube.

How did Goldstein discover the proton?

Summary. When an electron is removed from a hydrogen atom, a proton remains. Goldstein observed rays travelling in the opposite direction of the cathode rays in a cathode ray tube. He demonstrated that these rays were positive particles and called the canal rays.

What was Eugen Goldstein atomic model?

The Raisin Pudding Model of the Atom (Eugen Goldstein)

Goldstein concluded that in addition to the electrons, or cathode rays, that travel from the negatively charged cathode toward the positively charged anode, there is another ray that travels in the opposite direction, from the anode toward the cathode.
