	History: The cathode rays
		He noticed that the cathode rays were emitted perpendicular with respect to the surface of the cathode on the contrary to the shafts which propagate in all directions.
		When the A one is the cathode the spectroscope should record the light of the particles getting close (the Doppler shift should occur) When the B one is the cathode the spectroscope recorded light is caused bby the particles moving perpendicular with the respect to the spectroscope (there should be no Doppler shift).
		The cathode rays emitted at the cathode are passing through a small slot in the anode and through a wire net (the net has connections with the anode, and it's task was to screen the rest of the tube from electrode influence - electric field was only between the anode and the cathode).

	Cathode ray Summary
		Cathode rays are beams of electrons that emanate from acathode and are most commonly produced by heating a filament in a vacuum tube or by bombarding a target with positive ions.
		Cathode rays propagate in a straight line in the absence of external influences, but are deflected by electric or magnetic fields (which can be produced by placing high-voltage electrodes or magnets outside the vacuum tube - this explains the effect of magnets on a TV screen).
		In addition to their use within cathode ray tubes, higher energy beams of relativistic electrons (generated by various types of electron beam accelerators) are used extensively within many industries to perform precision electron beam welding, rapid curing of thermosetting plastics, and cross-linking of thermoplastics to improve their physical properties.

		During the cathode manufacturing process, a layer of oxide is formed naturally by exposing a cleaned aluminum cathode emitting surface to an oxygen plasma with the aluminum cathode connected as the cathode in an electrical circuit.
		The ceramic cathode in accordance with the present invention is produced by the use of powders which are tightly compressed into a mold to fill all of the voids.

	Investigating Cathode Rays
		At the end opposite to the cathode, was a cylinder that was closed at one end.
		The closed cylinder collected the cathode rays and was connected to an electroscope, which was used to determine the charge on the cathode rays.
		If we assumed that equal charges were present on the hydrogen ions and cathode ray particles, then the mass of the cathode ray particles was 1/1836 of the mass for the hydrogen ion.

	CATHODE - Online Information article about CATHODE
		When the current is so much increased that the glow covers the whole of the cathode an increase in current must result in an increase of the current density over the cathode, and this is accomplished by a rapid increase in the.
		distribution of the positive stream over the cathode is readiiy studied by covering the cathode with fused lithium chloride and observing the distribution of the red.glow.
		This suggests that the sputtering of the cathode is caused by the impact against it of the positive stream.

	J. J. Thomson 1897
		The deflexion of the cathode rays by the magnetic field was studied with the aid of the apparatus shown in fig.
		The cathode was placed in a side-tube fastened on to a bell-jar; the opening between this tube and the bell-jar was closed by a metallic plug with a slit in it; this plug was connected with the earth and was used as the anode.
		The cathode rays pass through this slit, and then strike against the two coaxial cylinders at the end of the tube; slits are cut in these cylinders, so that the cathode rays pass into the inside of the inner cylinder.

		In the current oxide cathode manufacturing process, a barium-strontium carbonate layer is either painted or sprayed on a nickel cathode base.
		Furthermore, in order to activate the cathode, the nitrocellulose must be burned off and the carbonates converted to oxides, by heating the cathode and drawing a current in vacuum.
		Cathode temperatures are measured using a laser-compensated pyrometer.

	Cold-Cathode Tube & Dekatron
		By varying the voltage on a grid which is between the anode and the cathode, and is in the path of the electrons, the flow of the electrons (ie.
		With all the cathodes at the same voltage a glow discharge from one of them to the anode will be transferred clockwise to its neighbouring cathode when a pulse is applied to all ten associated guide (transfer) electrodes.
		By applying phased pulses to the guide electrodes the discharge is forced to jump from one cathode to the next, and in the process voltage pulses are produced in sequence at the cathodes, which in the early Anita calculators is used for strobing the keys on the keyboard.

	Designing Common-Cathode Amplifiers
		The output signal of the common cathode amplifier is inverted with respect to the input signal.
		This circuit is similar to the bypassed cathode configuration with the exception of the removal of the cathode bypass capacitor, Ck.
		If the plate resistor, cathode resistor, and bypass capacitor values were different than the ones used in the example, the "center" point of the shelf would shift left or right, and the ratio between the top and bottom of the "shelf" would change.

	Cathode ray tube Summary
		The cathode rays were allowed to pass through a narrow aperture, effectively focusing them into a beam which appeared on the screen as a dot.
		The cathode ray tube or CRT, invented by Karl Ferdinand Braun, is the display device that was traditionally used in most computer displays, video monitors, televisions, radar displays and oscilloscopes.
		Cathode rays exist in the form of streams of high speed electrons emitted from the heating of cathode inside a vacuum tube at its rear end.

	Mysterious Rays
		But when the German physicist Heinrich Hertz passed the rays through an electric field created by metal plates inside a cathode ray tube, the rays were not deflected in the way that would be expected of electrically charged particles.
		When Lenard passed cathode rays through a metal foil and measured how far they traveled through various gases, he concluded that if these were particles, they had to be very small.
		Cathode rays are not only material particles, he suggested, but in fact the building blocks of the atom: they are the long-sought basic unit of all matter in the universe.

	Cathode Waste (Site not responding. Last check: 2007-09-11)
		When a pot has reached the end of its useful life, normally after about 6-7 years, it is rebuilt with a new carbon lining (the cathode).
		At this time it is necessary to dispose of the old lining, which consists of old refractory bricks and carbon, normally containing material from the electrolytic bath, plus a small amount of cyanide.
		The aluminium industry is currently researching other methods of cathode waste use — including extracting and recycling some of its useful components and using the waste material as a combustion source for power generation, or as raw materials in other industrial processes (eg, cement, steel).
