Ultrafast Electron Diffraction: How It Works

A new technology at SLAC uses high-energy electrons to unravel motions in materials that are faster than a tenth of a trillionth of a second, opening up new research opportunities in ultrafast science.

An enlightening video this is. SLAC is an acronym that should be spoken as Stanford Linear Accelerator Center. Acronyms are for ease of writing, not speaking.

Science Is AMAZINGGGG!!!!

Throughout the last century, it was great importance to know if the photon's motion is like a wave or like a particle's motion.
Saleh Theory give a coherent answer to this question on SALEH THEORY's Video: A Revolution in Light Theory

That is not something I've heard of, and presume it is a crackpot "theory". In real life, the final word on the subject is called "Q.E.D.", and Feynmann has a little book explaining it to the layman.
The "motion" is like a particle. It does not undulate as it moves along; those pictures are misleading. The wave nature is an internal property that cycles as it moves along, and the relative values of this property determines how different possible paths' probabilities are determined. Newtonian straight-line motion _emerges_ from this deeper explanation!

Hi SLAC, may I know what is the voltage needed to accelerate the electron to diffract around a nucleus?
