Particle Source, Copper Tube and Klystrons | HowStuffWorks
Particle Source. The particle source provides the particles that are to be accelerated. Particles can be electrons, protons, positrons (the first antimatter particle-- like an electron, but positively charged), ions, and nuclei of heavy atoms such as gold.At SLAC, an electron gun uses a laser to knock electrons off the surface of a semiconductor. The electrons then enter the accelerator ...

Copper Particles
The number of electrons in each of copper's shells is 2, 8, 18, 1 and its electron configuration is [Ar]3d 10 4s 1. The copper atom has a radius of 128 pm and a Van der Waals radius of 186 pm. Copper was first discovered by Early Man prior to 9000 BC. In its elemental form, copper has a reddish-orange metallic and lustrous appearance.

9.5: Free Electron Model of Metals
Metals, such as copper and aluminum, are held together by bonds that are very different from those of molecules. Rather than sharing and exchanging electrons, a metal is essentially held together by a system of free electrons that wander throughout the solid. The simplest model of a metal is the free electron model. This model views electrons ...

The Structure of Metals
Aluminum metal that has been saturated with copper at 550C will try to reject the copper atoms as it cools to room temperature. In theory, the solution could reject copper atoms by forming a polycrystalline structure composed of small crystals of more or less pure aluminum interspersed with small crystals of copper metal.
