Electronics

History

There are similarly high requirements for current coating applications in the battery sector, where a metallized plastic film is to replace metallic electrodes in lithium-ion batteries in the…

History

In order to be able to evaluate these energy densities, the electron beam must be very precisely adjustable in terms of beam diameter, energy and pulse duration. In the 60 years since the start of…

Overview - From Idea to Reality

From Idea to Reality

History

With the patented principle of the Vario Cathode, the electron beam power is now adjusted by changing the distance between the cathode and a fixed anode. This was made possible by moving the…

History

As a result, both the accelerating voltage and the cathode temperature could be kept constant with this solution, known as a Vario Anode. It also reduced the influence of the power control on the…

Figure 5: First, second and current generation of electron beam guns

History

Electron beam guns of this first generation still had a rather bulky design due to their high-voltage potential, directly water-cooled cathode systems and the required insulators. This was…

History

From the very beginning, the space charge in front of the cathode was used as an emission-limiting factor. This ensured the necessary stability of the beam power and beam quality against…
