Electron beams in manufacturing

Electron-beam furnace

An electron-beam furnace (EB furnace) is a type of vacuum furnace employing high-energy electron beam in vacuum as the means for delivery of heat to the material being melted. It is one of the electron-beam technologies. Electron-beam furnaces are used for production and refining of high-purity metals (especially titanium, vanadium, tantalum, niobium, hafnium, etc.) and some exotic alloys. The EB furnaces use a hot cathode for production of electrons and high voltage for accelerating them towards the target to be melted. An alternative for an electron-beam furnace can be an electric arc furnace in vacuum. Somewhat similar technologies are electron-beam melting and electron-beam welding. (Wikipedia).

Physically Constructing a Galvanic Cell (Electrochemistry)

Have you ever wondered how a battery works? It's redox chemistry! A redox reaction is split up into half cells, and you have an oxidation at the anode producing electrons to drive the reduction at the cathode. This flow of electrons can do work, and that's an electric current. This is call

DIY Atomic Beam Oven: The Stern Gerlach Experiment Pt. 3

After a long time there is again a video about the Stern-Gerlach experiment. With this experiment one can demonstrate quantum mechanical effects by deflecting atoms in a high vacuum, depending on the spin of the electrons. Today's video is about the atomic beam furnace, which is used to g
