Goldstein used a <a href="http://kulkul.xahoihoctap.net/scientific-terms.html?view=mediawiki&article=Gas_filled_tube" target="_blank">gas discharge tube</a> which had a perforated <a href="http://kulkul.xahoihoctap.net/scientific-terms.html?view=mediawiki&article=Cathode" target="_blank">cathode</a>. A "ray" is produced in the holes (canals) in the cathode and travels in a direction opposite to the "<a href="http://kulkul.xahoihoctap.net/scientific-terms.html?view=mediawiki&article=Cathode_ray" target="_blank">cathode rays</a>," which are streams of <a href="http://kulkul.xahoihoctap.net/scientific-terms.html?view=mediawiki&article=Electron" target="_blank">electrons</a>. Goldstein called these positive rays "Kanalstrahlen" - canal rays because it looks like they are passing through a canal. In 1907 a study of how this "ray" was deflected in a <a href="http://kulkul.xahoihoctap.net/scientific-terms.html?view=mediawiki&article=Magnetic_field" target="_blank">magnetic field</a>, revealed that the <a href="http://kulkul.xahoihoctap.net/scientific-terms.html?view=mediawiki&article=Particle_physics" target="_blank">particles</a> making up the ray were not all the same <a href="http://kulkul.xahoihoctap.net/scientific-terms.html?view=mediawiki&article=Mass" target="_blank">mass</a>. The lightest, formed when there was a little <a href="http://kulkul.xahoihoctap.net/scientific-terms.html?view=mediawiki&article=Hydrogen" target="_blank">hydrogen</a> in the tube, was calculated to be 1837 times as massive as an <a href="http://kulkul.xahoihoctap.net/scientific-terms.html?view=mediawiki&article=Electron" target="_blank">electron</a>.
