so a good bit of electron optics are required to get a small point. Focusing is done through a series of pinholes and electrostatic deflectors, much like you’d see in an old oscilloscope CRT.

did, by converting the TV into a crude oscilloscope. The trick is to take control of the two deflection coils that move the electron beam inside the CRT in the horizontal and vertical directions.

Krasnow made his electron gun out of a thin tungsten ... To create that video, Krasnow bought an old oscilloscope. As the beam moves across the surface, the clouds of electrons emitted from ...

Because the one-electron beam must be shared by two channels ... It belongs to the relatively rare class of dual-beam oscilloscopes – essentially combining two scopes in one chassis. This not only ...

Once aligned, the electron beam leaving the structure goes through ... on the same detector and oscilloscope. We observe the measured arrival time of the two signals and adjust a four-pass optical ...

Commercially available oscilloscopes weren’t available until the early 1930s, however, when General Radio began offering the Type 535A Electron Oscillograph, shown in Figure 1. The General Radio Type ...

Horányi and colleagues have discovered a new method for combatting lunar dust’s static cling, using a low-powered electron beam to make dust particles fly off surfaces. It complements existing ...

They used an electron beam, produced by a Transmission Electron Microscope (TEM) to tractor the nanoparticle with a piconewton force, enabling them to move it several microns in any direction at ...
