BOA is fully parallelized. Its particle pusher and field solver use every available CPU cores. The GUI of BOA is powerful and intuitive allowing the user to create a case for a given geometry in matter of minutes. Its post-processor is able to plot particle trajectories selectively by its currents, ID's or generations, and electromagnetic fields in regions, on a surface, along an arbitrary line or...
To improve RF source performance and operate at higher frequencies, designers are investigating distributed beam devices, including sheet beam and multiple beam sources. Non-axially symmetric geometries provide significant challenges for computational design. In addition to the increased computational resources required, the available parameter space makes manual design difficult or impractical. This...
An automated, GUI-accessible optimizer has been implemented into Beam Optics Analyzer; the optimizer uses iterative methods to model electron guns and surface electric fields.
Iterative computational design of asymmetrical electron beam devices, such as sheet beam and multiple beam klystrons, requires 3D analysis involving complex geometries. Manual, iterative design is extremely difficult and impractical for all but the simplest devices. Computer optimization tools and techniques are described that provide automated design of these devices using common personal computers...
Computer optimization can dramatically reduce the time and cost to design electron beam devices. It also allows design of complex, 3D devices that would be impractical with manual design. Recent implementation of a magnetic solver into a 3D finite element electron beam trajectory code is allowing optimized design of the electrostatic, optical and magnetic configuration of 3D device. The process and...
