Cathode rays

The canal rays were used for the discovery of proton by Eugen Goldstein.The cathode rays were used for the discovery of electrons by J.J. Thomson.
The canal rays consist of positively charged particles known as protons.The cathode rays consists of negatively charged particles known as electrons.
These rays start from the anode and travel towards the cathode.These rays start from cathode and travel towards anode.
The charge to mass ratio of these rays depend on the nature of the gas in the discharge tube.The charge to mass ratio is independent of the nature of the gas in the discharge tube.
