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.

At the beginning of an experiment, a beam of electrons may have a rest energy of 1/2 million electron volts; it is directed through a linear "pre-accelerator" (or "injector") where the energy is ...

Electron linear accelerators are being used throughout the world in increasing numbers in a variety of important applications. Foremost among these is their role in the treatment of cancer. Commercial ...

A new upgrade to the world’s most powerful X-ray free-electron laser has been given ... The X-ray laser is the Linac (short for linear accelerator) Coherent Light Source (LCLS) at the SLAC ...

In layman’s terms it was a “cancer zapper”; a linear accelerator ... a high power electron beam without the x-ray target in place. Attempting to activate the accelerator in an invalid ...

His colleague Shayhan Chunkath, also a PhD candidate at the University of Auckland, has brought a peptide, a tiny protein ...

Electron beams are also used for sterilizing medical products and foods, and to disinfect sewage water. They are used widely in the automotive and aerospace industries, for machine construction, and ...

To accomplish this, the physicists behind the new study tweaked an electron gun until it produced a pulse of just one attosecond. These pulses hit the "sample" being studied, and as the electrons ...

In a study published in Nature Communications, scientists created a blueprint for creating ultrabright and ultrashort pulses of electron beams for the next generation of particle accelerator research.

1364 - First recorded use of a firearm. 1380 - Hand guns are known across Europe. 1400s - The matchlock gun appears. Before the matchlock, guns were fired by holding a burning wick to a "touch ...

Whether you frequent a local pool or are planning a trip to the beach, water guns are a great addition to your outdoor activities and promise endless fun. Plus, they aren't just for kids.
