Visualisation d'une charge d'or dans un évaporateur thermique par canon à électrons

Observation of gold charge in an electron beam thermal evaporator. The electrons bombard the solid gold, which heats up and becomes liquid. The pressure in the chamber being very low (high vacuum), the liquid gold evaporates. The gold vapour thus formed then condenses on a substrate positioned opposite, forming a thin layer. With this type of equipment, it is possible to achieve an accuracy of a few tenths of a nanometre in terms of the thickness of the thin layer that is deposited.

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
