WEBINAR SERIES
Simulating charged-particle sources and beams
Date: Wednesday, March 28, 2012
Time: 03:00 PM BST
|
 From electron lithography and ion sources to field-tip emitters for flat-screen displays, the modelling of charged-particle devices is critical in ensuring optimum efficiency and performance. This webinar discusses the modelling of space-charge-limited emission and particle tracking using the Opera software suite.
Simulation software lets designers characterize their devices simply and effectively. Coupled multiphysics simulations allow the study of beam charging and current flow in imperfect dielectrics and heating effects from both primary and secondary emission. Advanced interactions can be included in simulations, such as the ionization of a background gas to form plasma ion beams.
We will explore a variety of systems, from simple thermal electron sources to space-charge-compensated ion beams and multispecies plasmas. |
The webinar will run for approximately 45 minutes with time for a Q&A at the end.

Speaker: Stephen M Elliott, Owner, Thin Film Consulting
Stephen Elliott began working in charged-particle physics in 1975 at the Nuclear Physics Laboratory of the University of Pittsburgh. During his career, he has worked on the development of ion-beam sources, electron guns, linear accelerators, field-effect emitting devices, magnetron sputtering cathodes and plasma-deposited thin-film coatings. In 1991 he founded Thin Film Consulting to provide services in charged-particle device design, thin-film vapour sources, materials science and process development. In 1993 he began using Opera software for the development of charged-particle devices. Since then, he has developed models for the simulation of X-ray tubes, neutron generators, plasma and surface ion-beam sources, electron guns, cavity resonators, klystrons, ion spacecraft thrusters and thin-film-deposition vapour sources. |
