canal rays n. [after German Kanalstrahlen, plural noun (E. Goldstein 1886, in Berliner Berichte 39 691); so called on account of the openings in the cathode through which the ions pass (compare quot. 1957)] Physics (now historical) streams of positive ions which are produced in a high-vacuum discharge tube and move towards the cathode, some of them passing through openings in it (cf. positive rays n. at positive adj. and n. Compounds).Also (chiefly in attributive use) in singular.

canal rays1897

1897 Jrnl. Physical Chem. 1 752 A number of substances were subjected to the action of: 1, Cathode rays; 2, Röntgen rays; 3, Becquerel's rays; 4, Goldstein's (canal rays); 5, Hertz (discharge) rays.

1904 E. Rutherford in Technics July 12/2 The rays from radium are very similar to those produced when a strong electric discharge is sent through a vacuum tube... The α rays are very analogous to the ‘canal’ rays discovered by Goldstein.

1916 Sci. Abstr. A. 19 154 The inhomogeneity of the field in the canal-ray tube.

1957 Encycl. Brit. XVIII. 882 c/1 Goldstein first observed..streams of luminous gas back of a perforated cathode..as if..ionizing particles were coming through the holes..and ionizing the gas... These radiations..were first called kanalstrahlen, or canal rays.

2004 B. Bunch & A. Hellemans Hist. Sci. & Technol. 422/1 Later canal rays will be found to consist of ions that have had electrons stripped in producing the cathode ray.
