From Ideas To Implementation Experiments
... We modelled a semiconductor using marbles in a Petri dish, with each marble representing an electron. Removing a marble from the dish represented the creation of a hole. As the dish is disturbed by moving it, simulating the application of an electric field, the position of the hole changed as marble ...

... attached to each detector element in the thin-film-transistor array. Electrons are produced, captured by storage capacitors at each element, and then actively read by the electronic switching of the transistors. Although the flat panel array directly reads out the signal, the x-rays go through a con ...

The transit time of the ions depends more on the input system electric field and the mass of the ions than on the distance from the cathode at which they originate. The usual ions are H+, and He+, and CH +(typical transit times of abo ...

The Acceleration of Electrons by Magnetic Induction
... In the past the acceleration of electrons to very high voltage has required the generation of the full voltage and the application of that voltage to an accelerating tube containing the electron beam. No convenient method for repeated acceleration through a small potential difference has been availa ...

They are very different from each other in many ways. One way they are different is their "charge." Protons have a p ...

Video camera tube
The video camera tube was a type of cathode ray tube used to capture the television image prior to the introduction of charge-coupled devices (CCDs) in the 1980s. Several different types of tubes were in use from the early 1930s to the 1980s.In these tubes, the cathode ray was scanned across a target which was illuminated by the scene to be broadcast. The resultant current was dependent on the brightness of the image on the target. The size of the striking ray was tiny compared to the size of the target, allowing 483 horizontal scan lines per image in the NTSC format, or 576 lines in PAL.
