Designing a Converging-beam Electron Gun and Focusing Solenoid

A frequent electron gun design goal is to produce a converging beam that matches to a focusing solenoid. This white paper describes a case study for a system to generate a narrow electron beam at high-current density and to transport it over a distance exceeding 8.0 cm for experiments on high- frequency microwave generation. Read More

Improved Trak Models for Beam-generated Magnetic Fields

This paper describes new methods in the Trak charged-particle optics code to find the self-consistent, beam-generated magnetic fields of high-current beams. The modifications are helpful for general work with relativistic electron beams. They are critical for simulations of high-power microwave devices like the relativistic magnetron and the magnetically-insulated line oscillator. Read More
