Latest Cathode ray Stories
Vortex beams, rotating like a tornado, offer completely new possibilities for electron microscopy. A method of producing extremely intense vortex beams has been discovered at the Vienna University of Technology (TU Vienna).
Understanding weather patterns here on Earth is a complicated process, with scientists teasing apart different kinds of atmospheric movements, such as the great jet streams that can move across a whole hemisphere versus more localized, intricate flows, to create a whole picture.
Not to pick up electrons, but tweezers made of electrons.
A lightning researcher at the University of Bath has discovered that during thunderstorms, giant natural particle accelerators can form 40 km above the surface of the Earth.
Thomas T. Goldsmith Jr., who helped bring televisions into U.S homes, has died in Lacey, Wash., at the age of 99, his son Judson says. The New York Times said Sunday that by working with scientist Allen B.
A new electron microscope recently installed in Cornell's Duffield Hall is enabling scientists for the first time to form images that uniquely identify individual atoms in a crystal and see how those atoms bond to one another - and in living color.
The Cathode Ray Tube, which has internal or external means to accelerate and deflect electron beams, is a vacuum tube containing an electron gun and a fluorescent screen. The electron beams that are deflected are used to create images in the form of light emitted from the fluorescent screen. The CRT works by using an evacuated glass envelope which is large, deep, heavy, and relatively fragile. Ferdinand Braun is credited with the first CRT in 1897. It can also be known as the Braun tube....
Vladimir Kozmich Zworykin (July 30, 1889 - July 29, 1982) was a Russian-American engineer, inventor, and initiator of television technology. One of his accomplishments includes the invention of a television transmitting and receiving system utilizing cathode ray tubes. In the early thirties, he was instrumental in the physical production of components used in the television, including charge storage-type tubes, infrared image tubes, and the electron microscope. Although many biographers...
