Field Precision software tips

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 [...]

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 [...]

We’re expanding our collection of tutorials illustrating finite-element simulation techniques. They address practical applications as well as benchmark comparisons with theory. You can browse the full set in our Technical Library at http://www.fieldp.com/library.html.

Finding inductance is one of the main uses of magnetic field software. We’ve just posted a tutorial that shows how to use PerMag to [...]

We added seven new tutorials to our technical library:

1) Trak design of an electron injector for a coupled-cavity linear accelerator. Electron gun that maintains its focal properties over a broad range of current for high capture efficiency in an electron linac.

2) Calculating field stress on a high-voltage insulator with HiPhi. Determination of field stress over the [...]
