Electron Charge to Mass Ratio Demo
... In this experiment we will measure a fundamental property of the electron, the ratio of its charge to its mass. In the experiment, a beam of electrons accelerated by a potential difference is bent into a circular path by a magnetic field. The beam is in a glass container containing a small amount of ...

Abstract
... The electron microscope focuses electrons at a sample to be viewed and then spreads the beam out to display a magnified image on a screen or creates an image of reflected or secondary electrons from scanning the beam across the sample in a raster. Secondary electrons are knocked off of atoms when st ...

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.
