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.

The Hidden Benefits of VoIP Revealed

The appeal of VoIP is straightforward: By converging voice and data into a single, unified network, businesses can lower costs and increase productivity, as the scaled-down VoIP infrastructure is easier and less expensive to maintain. Read this white paper to gain a competitive advantage with VoIP’s four “secret weapons”: rich media, mobility, unified communications, and virtual workplaces. Read More

10 Critical Questions to Ask a Manufacturing ERP Vendor

Many manufacturers are focusing on the wrong issues when considering ERP solutions. The ERP industry has earned such a poor reputation for delivery in the last 20 years that users have learned to live within a very narrow set of constraints—and those constraints have been in place for so long that the questions we hear are built with those constraints already assumed. Now is the time to break free of this mindset and ask the more important questions. Know what questions to ask. 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
