Goldstein called these positive rays Kanalstrahlen, "channel rays", or "canal rays", because these rays passed through the holes or channels in the cathode. The process by which anode rays are formed in a gas-discharge anode ray tube is as follows.
Crookes X-ray tube from around 1910 Another Crookes x-ray tube. The device attached to the neck of the tube (right) is an "osmotic softener". When the voltage applied to a Crookes tube is high enough, around 5,000 volts or greater, [16] it can accelerate the electrons to a high enough velocity to create X-rays when they hit the anode or the glass wall of the tube.
Eugen Goldstein observes canal rays. 1898 Wilhelm Wien Wilhelm Wien demonstrates that canal rays can be deflected using strong electric and magnetic fields. He shows that the mass-to-charge ratio of the particles have opposite polarity and is much larger compared to the electron. He also realizes that the particle mass is similar to the one of ...

They were first observed in 1859 by German physicist Julius Plücker and Johann Wilhelm Hittorf, [1] and were named in 1876 by Eugen Goldstein Kathodenstrahlen, or cathode rays. [2] [3] In 1897, British physicist J. J. Thomson showed that cathode rays were composed of a previously unknown negatively charged particle, which was later named the ...

Replica of F.W. Aston's third mass spectrometer. In 1886, Eugen Goldstein observed rays in gas discharges under low pressure that traveled away from the anode and through channels in a perforated cathode, opposite to the direction of negatively charged cathode rays (which travel from cathode to anode).
