Three new tutorials are available in the technical library that describe design studies for a hollow-beam, high-power klystron. The documents include material of general interest to anyone interested in high-current electron beam technology.
In the case study, an annular electron beam with kinetic energy 100 keV and power 20 MW power is generated from an immersed cathode [...]
Plotting is critical to understand meshes and field solutions in three-dimensional spaces. In consequence, we have included a wide variety of options for creating plots in MetaMesh and the analysis programs PhiView, MagView, HWV, RFE3View and Aerial. For example, the following information is neede to create a 3D view of a mesh:
Parameters of the point of [...]
We’re making some major advances in the graphics capabilities of programs in the 3D AMaze series. We expect to release updates in the early Fall. The improvements lie in three areas:
It takes effort and experimentation to set up optimal 2D or 3D views in postprocessors like PhiView and MagView. We are adding an option to [...]
One of the major task in simulating three-dimensional electromagnets is the definition of complex drive coils. The utility MagWinder is part of the Magnum program suite. Drive circuits are represented in Magnum by dividing them into a large set of short segments (or current elements). MagWinder provides an interactive environment where users can build magnet windings [...]
Vacuum electronic devices for microwave generation (e.g., klystron, traveling wave tube,…) require high-current-density electron beams matched to a focusing solenoid. The standard approach is to use a gun outside the field that generates a converging beam. The motivation is to allow relatively low current density at the cathode, consistent with operation at moderate temperature for long [...]
