Definitions
- the present invention is intended 5 to serve the said purpose.
- the high-vacuum chamber contains a photoelectric cathode 5 to which is imparted a high negative potential in reference to the partition wall 2. If the photo-electric coat is feebly irradiated across the window 6 then the electrons issuing from the cathode 5, under the influence of the strong electrical field, undergo high acceleration whereby they are rendered capable of traveling through the partition 2 and. of causing ionization in space or chamber 4 of the gas and thereby luminescence thereof. In the presence of an adequately high accelerative potential a largervolume of light will emerge through window 1 than had entered into the apparatus by way of the input window 8.
- a light amplifier system which comprises an envelope divided into a pair of chambers one of said chambers being a high vacuum chamber and the other of said chambers being a gas filled chamber, an electron permeable partition separating said chambers, a photoelectric element positioned in the chamber subjected to a high vac- 10 uum, and a voltage source for producing within the tube an electrical field to cause a flow of electrons from the high vacuum chamber to the gas filled chamber to cause the gaseous filling thereof to become ionized upon the passage 7 of photoelectrons through said electron permeable partition whereby a magnified effect of the light initiatingthe photoelectron stream is obtained in said gas filled chamber.
- a light amplifier which comprises an envelope divided into a plurality of separated chambers, a photoelectrically responsive electrode element in the first of said chambers, an electron permeable partition separating said chambers one from the other, a gaseous filling contained within the second of said chambers, and a voltage source connected between the electron permeable and the photoelectrically responsive electrode to cause the photoelectrons to pass from the first chamber content thereof is'ionized upon the passage of photoelectrons through said medium.

LIGHT AMPLIFIER Original Filed Jan 19, 1952 INVENTOR OTTO SCHNF. R
1 A BY f MM ATTORNEY Patented June 11, 1935 LIGHT ADIPLIFIER Otto Schriever, Berlin, Germany, assignor to Telefunken Gesellschalt fiir Drahtlose Telegraphic m. b. H., Berlin, Germany i Application January 19, 1932, Serial No. 587,467. Renewed March 4, 1935. In Germany January 2 Claims.
For some purposes such as television there exists a demand for ways and means adapted to change directly feeble luminous impressions into strong light actions. The present invention is intended 5 to serve the said purpose.
pressure, that is, to a high vacuum, whereas the other chamber 4, for example, contains a gas subject to a low pressine. -The high-vacuum chamber contains a photoelectric cathode 5 to which is imparted a high negative potential in reference to the partition wall 2. If the photo-electric coat is feebly irradiated across the window 6 then the electrons issuing from the cathode 5, under the influence of the strong electrical field, undergo high acceleration whereby they are rendered capable of traveling through the partition 2 and. of causing ionization in space or chamber 4 of the gas and thereby luminescence thereof. In the presence of an adequately high accelerative potential a largervolume of light will emerge through window 1 than had entered into the apparatus by way of the input window 8.
Having now described my invention, what I claim and desire to secure by Letters Patent is I the following:
1. A light amplifier system which comprises an envelope divided into a pair of chambers one of said chambers being a high vacuum chamber and the other of said chambers being a gas filled chamber, an electron permeable partition separating said chambers, a photoelectric element positioned in the chamber subjected to a high vac- 10 uum, and a voltage source for producing within the tube an electrical field to cause a flow of electrons from the high vacuum chamber to the gas filled chamber to cause the gaseous filling thereof to become ionized upon the passage 7 of photoelectrons through said electron permeable partition whereby a magnified effect of the light initiatingthe photoelectron stream is obtained in said gas filled chamber.
2. A light amplifier which comprises an envelope divided into a plurality of separated chambers, a photoelectrically responsive electrode element in the first of said chambers, an electron permeable partition separating said chambers one from the other, a gaseous filling contained within the second of said chambers, and a voltage source connected between the electron permeable and the photoelectrically responsive electrode to cause the photoelectrons to pass from the first chamber content thereof is'ionized upon the passage of photoelectrons through said medium.
