A Brief Account of Radio-activity The impact of cathode rays produces after a time perceptible changes in the glass. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" This display uses a five inch, high resolution cathode ray tube. Preliminary Specifications: Programmed Data Processor Model Three (PDP-3) October, 1960 The other common ray is the cathode ray type which does not consist of vibrations but of a stream of electrons, negative particles of electricity, traveling in straight lines of high velocity. Astounding Stories, May, 1931 When moonlight, or any other reflected light of the same composition falls on it, it acts on the ray much as the button of a Roentgen tube acts on a cathode ray. Astounding Stories of Super-Science April 1930 I knew that if such a condition existed, the positively charged dust would be pulled down toward the source of the negative particle stream, which must, in many ways, resemble a cathode ray. The Great Drought The same apparatus can be used to show that the passage of cathode rays through a gas makes it a conductor of electricity. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" It was left, however, for Professor Röntgen to discover that during the discharge quite other rays are set free, which differ greatly from those described by Lenard as cathode rays. Little Masterpieces of Science: Invention and Discovery The cathode ray, when properly used, will bombard the atoms and knock electrons loose. Astounding Stories, May, 1931 As the cathode ray is absorbed and an entirely new ray, the X-ray, is given off by the button, just so is the reflected moonlight absorbed and a new ray of ultra-violet given off. Astounding Stories of Super-Science April 1930 There was a glass bulb above—the generator of a cathode ray, obviously—and electro-magnets below and on each side. Astounding Stories of Super-Science July 1930 The conductivity produced by the passage of cathode rays through a gas diminishes rapidly with the pressure. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" With his magnet the scientist throws a rope around the cathode rays and drags them whithersoever he will.

The Ultimate Weapon He looked approvingly at the exquisite workmanship of an instrument where a generator of the cathode ray and an intricate maze of tubing surmounted electro-magnets and a round lead bulb. Astounding Stories of Super-Science July 1930 The tube is then exhausted until the cathode rays strike against the window. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" This is to reduce the heating consequent on the projection of cathode rays from the edges of the disc against the glass tube.

Creative Chemistry Descriptive of Recent Achievements in the Chemical Industries It is also identical with the cathode ray of the vacuum tube. The Birth-Time of the World and Other Scientific Essays The beta particles emanating from radium were soon identified with the electrons of the cathode ray. Occult Chemistry Clairvoyant Observations on the Chemical Elements Scattering of the Negative Electrodes.—In addition to the cathode rays, portions of metal start normally from the cathode and form a metallic deposit on the walls of the tube. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" The pressure at which the maximum heating of the anode by the cathode rays occurs is a good deal higher than that at which the maximum Roentgen effect is produced. On Laboratory Arts All the others, even the newly discovered cathode rays, are subject to obstruction by certain forms of matter; that is, to them certain forms of matter are opaque. Notable Events of the Nineteenth Century Great Deeds of Men and Nations and the Progress of the World Thomson adopts an analogous idea, and states the precise way in which the pulsations may be produced at the moment when the electrified particles forming the cathode rays suddenly strike the anticathode wall. The New Physics and Its Evolution It was the well-known photographic properties of ordinary lightning that made Dr. Morton suspect that cathode rays are produced freely in the air when there is an electric discharge from the heavens. McClure's Magazine, Vol. 6, No. 5, April, 1896 The particles of metal are at low pressures deflected by a magnet, though not nearly to the same extent as the cathode rays. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" Monitors, CRT's, screens, cathode ray tubes, whatever you want to call them. Terminal Compromise: computer terrorism: when privacy and freedom are the victims: a novel It was for this reason that the name of "cathode rays" has been given to the new radiant force; but Dr. Röntgen himself called the phenomena the X, or unknown, rays. Notable Events of the Nineteenth Century Great Deeds of Men and Nations and the Progress of the World It is right to add that some authors, notwithstanding the proved impossibility of deviating them in a magnetic field, have not renounced the idea of comparing them with the cathode rays. The New Physics and Its Evolution Reasoning thus, he resolved to search for cathode rays in the ten-inch lightning flash he was able to produce between the poles of his immense Holtz machine, probably the largest in this country. McClure's Magazine, Vol. 6, No. 5, April, 1896 This experiment shows that the cathode rays are accompanied by a stream of negative electrification. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" For cathode rays have stolen through This maiden so deceiving; And thus her heart I've photographed, And seeing is believing. Cap and Gown A Treasury of College Verse In the first decade of the century it had been generally supposed that the X ray, or cathode ray, had been developed and applied to the utmost extent of its capability. The Great Stone of Sardis Professor Lenard's fundamental idea was to study the cathode rays under conditions different from those in which they are produced. The New Physics and Its Evolution Dr. Morton proposed to see if he could not prove the existence of cathode rays between the poles by causing them to picture in shadow, upon the sensitized plate, the letters thus exposed. McClure's Magazine, Vol. 6, No. 5, April, 1896 From the window, too, proceed rays which, like the cathode rays, can produce phosphorescence, for certain bodies phosphoresce when placed in the neighbourhood of the window. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" The cathode rays, for instance, were found to shoot forth into space perpendicularly from the surface of the cathode, without regard to the position of the anode. Man or Matter But Roland Clewe had come to believe in the existence of a photic force, somewhat similar to the cathode ray, but of infinitely greater significance and importance to the searcher after physical truth. The Great Stone of Sardis The great physicist had, in fact, shortly before his premature death, taken up this important question of the cathode rays, and his genius left there, as elsewhere, its powerful impress. The New Physics and Its Evolution His success is, no doubt, largely due to the fact that for years he had been experimenting constantly with vacuum tubes similar to the Crookes tubes used in producing the cathode rays. McClure's Magazine, Vol. 6, No. 5, April, 1896 As, however, it is convenient to distinguish between cathode rays outside and inside the tube, we shall call the former Lenard rays. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" This brings us to the discovery of cathode rays and the phenomena accompanying them, from which the latest stage in the history of electricity originated. Man or Matter These are the famous "cathode rays" of which we have recently heard so much. The Story of Electricity This convection of negative electricity by the cathode rays seems quite inexplicable on the hypothesis that the rays are ethereal radiations. The New Physics and Its Evolution Where these rays strike solid objects, they give rise to the Rontgen rays now so well known; but it is with the cathode rays themselves that we are concerned. Darwin and Modern Science Diffuse Reflection of Cathode Rays.—When cathode rays fall upon a surface, whether of an insulator or a conductor, cathode rays start from the surface in all directions. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" Shortly afterwards Lenard discovered that the cathode rays can be made to pass from the inside of a discharge tube to the outside air. A History of Science — Volume 3 M. Villard calls them magneto-cathode rays, and according to M. Fortin these rays may be ordinary cathode rays, but of very slight velocity. The New Physics and Its Evolution In the interior of a Crookes tube he collected a pencil of cathode rays in a metal cylinder. The New Physics and Its Evolution The mass of a cathode ray particle, or corpuscle, as Thomson, adopting Newton's name, called it, is about the eight-hundredth part of the mass of a hydrogen atom. Darwin and Modern Science The cathode rays make the body emit a continuous spectrum, while the spectrum produced by the positive rays often shows bright lines. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" The rays producing this glow were not the cathode rays, although apparently arising from them, and are what have since been called the Roentgen rays, or X-rays. A History of Science — Volume 3 Although they are all formed of identical electrons, there may be various cathode rays, because the velocity is not exactly the same for all electrons. The New Physics and Its Evolution At the spot where the cathode rays strike the walls of the tube the essentially different X rays appear. The New Physics and Its Evolution The beta rays are on all points similar to the cathode rays; they are, as M. and Madame Curie have shown, negatively charged, and the charge they carry is always the same. The New Physics and Its Evolution Their size is that of the electrons, and their velocity is generally greater than that of the cathode rays, while it may become almost that of light. The New Physics and Its Evolution In the closing days of December, 1895, Professor Wilhelm Konrad Roentgen, of Wurzburg, announced that he had made the discovery of the remarkable effect arising from the cathode rays to which reference was made above. A History of Science — Volume 3 There is reason for believing, therefore, that the cathode rays are rapidly moving charges of negative electricity. A History of Science — Volume 3 It may be, again, that in certain regions of the tube cathode rays are met with diffused by some solid object, without having thereby changed their nature.
