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.

Converging Branch IT Infrastructure the Right Way

Many organizations continue to struggle with outdated IT architectures in branch offices. There is a fundamentally better and less costly way to architect your branch IT. Whether driven by a server refresh project, or by the need to solve a more acute problem posed by your branch IT, adopting a branch converged infrastructure solution as your next branch architecture can drive significant dollar savings while securing data and improving recovery.  Read More

Converging Branch Infrastructure for Simplicity, Efficiency, and Lower Costs

  • Source: IDC
  • Written By:
  • Published:
Many organizations have invested in converged infrastructure for data centers. In remote offices however, servers and storage exist as isolated islands of disparate infrastructure that require management through separate operational processes and procedures. This approach is expensive and puts your data at risk.

However, branch converged infrastructure architecture allows IT to consolidate in the branch office to minimize the IT footprint needed to run branch applications—all the while... 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
