It was first discovered by Goldstein with anode ray experiment.
In this experiment, a discharged tube filled with a noble gas was taken and a potential difference of 10,000V was applied . The pressure within the discharge was made as low as 0.01 mm of Hg. I this a perforated cathode was taken and its behind wall has been coated with fluorescent substance when a bluish illumination was seen.
later, it was proved that the beams of anode ray were actually beams of protons.
