Reader [Xellers] sent in his newest instructable: DIY Electron Accelerator: A Cathode Ray Tube in a Wine Bottle. While not exactly what you might think of a cathode ray tube, the basics are in place.

We’ve never seen anyone make their own x-ray tube, though, and it’s doubtful we’ll ever see the skill and craftsmanship that went into this build again. An x-ray tube is a simple device ...

"A cathode-ray tube is used upon the face of which the trace of the ray or electron beam can be seen. One or more targets, such as pictures of airplanes, for example, are placed upon the face of ...

SEM images are formed when the electron beam position on the sample surface is synchronized with the CRT, or cathode ray tube viewing screen. At each location where the electron beam strikes the ...

With free-electron lasers, such as the one that will soon be operating at the Stanford Linear Accelerator Center, X-ray microscopy will eventually allow us to image dynamics of molecules on the ...

Free-electron lasers create coherent light by constantly accelerating a beam of electrons. Free-electron lasers are particularly useful because they can produce radiation with a short-wavelength ...

Arising from an IAEA coordinated research project, this publication reports on research to develop new tools in food irradiation and to rapidly ascertain treatment parameters before irradiation, ...

What are X-Ray Free-Electron Lasers? X-ray free-electron lasers (XFELs) are a revolutionary type of X-ray source that produce ultra-short, highly intense pulses of X-rays. Unlike conventional X-ray ...
