All Electrostatic Applications
EADS, Innovation Works in the UK uses CST EM STUDIO® to aid in the simulation of aircraft fuel systems.
EADS has developed an internal code for modelling the filling of an aircraft fuel tank. The code simulates this scenario and outputs the electric field, charge density and potential at various points in the tank and fuel over the filling period.

This article is concerned with the features required for a 3D electrostatic computation, using CST EM STUDIO® (CST EMS) of a power engineering application for which a medium voltage SF6 main ring unit load break switch manufactured by ABB Distribution, Skien, Norway [1] has been taken.
A CAD model of the equipment was provided with the permission and courtesy of ABB, Bad Dättwil, Switzerland.
Electrostatic simulations are used to indicate the locations of critical spots where discharges may occur. For such an analysis, workflow and accuracy are essential requirements.

Electromagnetic simulation using CST EMS is now established at the heart of these significant improvements to the development and manufacturing processes. The software is extremely reliable, robust and efficient. The CST EMS development team reacts swiftly to our needs and feature requests and is always receptive to new ideas and
suggestions. As a consequence, we believe that product support, in addition to the software‘s powerful features, has contributed to the success of EM simulation at Sirona

This article describes the hot and cold test analysis of a traveling wave tube. Such a simulation uses a broad spectrum of the solvers available in CST STUDIO SUITE™. The complete simulation procedure is shown. First the electron gun is analyzed. Then the dispersion characteristics of the slow wave structure are evaluated. Finally the particle in cell (PIC) simulation of the beam inside the vacuum tube is performed.

„CST EMS ist mittlerweile bei Siemens ein fester Bestandteil des Entwicklungsprozesses verschiedenster
Leistungstransformatorkomponenten geworden, insbesondere wegen
der einfachen Bedienungsoberfläche und der Vielfalt der Löser. Dank der sehr engen Zusammenarbeit mit dem CST EMS Entwicklungsteam
wurden Wünsche, Anregungen und Ideen immer offen aufgegriffen
und zügig umgesetzt. Dies bildet die Basis für unsere Entscheidung auch
weiterhin verstärkt die von CST angebotenen Lösungen anzuwenden.“

Electron guns are the starting point of every charged particle application. There the DC energy is translated into an extracted beam which later on interacts with all kinds of RF structures. The design and analysis of an electron gun can be performed with the tracking code of CST PARTICLE STUDIO® as shown in this article.
