Using Opera for Fusion Energy Applications

3pm :: Wednesday 25th October :: 2017 In this webinar we will show examples of fusion design calculations using Opera, and we will demonstrate features of Opera which help users create and analyse fusion simulations and models easily. These include simulating plasma disruptions and motion, where the plasma current decays and / or the plasma moves [...] Posted in Magnets,Plasma Discharge

X-ray tube simulation webinar

This webinar reviewed the requirements of common types of X-ray tube, and looked at how the capabilities of Opera help designers meet the required characteristics of the electron beam and to optimize designs. We considered a range of phenomena and physical effects, including generation and focussing of the beam, and deposition of the beam energy [...] Posted in X-Ray Tubes

How to simulate industrial designs for multi-physics applications

Opera is a suite of multi-physics analysis programs that includes electromagnetics, stress and thermal analysis. To highlight the main points that make it suitable for industrial designs: Opera includes an easy-to-use 3D Modeller, allowing models to be created or imported -in a wide variety of standard CAD formats; Scripting in the Modeller makes it a [...] Posted in Charged Particle Devices,CPD Papers,How to...,Induction Welding

EUGM 2017: Recent developments to Opera’s magnetron sputter simulation tool

Presenter: Applications engineer, Cobham Technical Services Abstract: Sputter coating is widely used for the fabrication of thin films in a highly diverse range of applications - from decorative and low emissivity coat­ings on glass, through to deposition on circuits and engineering coating on products used in some of today’s most demanding applications. Of the many [...] Posted in Charged Particle Devices,General,Induction Welding

How to simulate magnetron sputtering

By Nigel Atkinson So, what is magnetron sputtering? It is a physical vapour deposition technique, in which a plasma in a chamber is used to generate ions that are accelerated towards a negative target, ejecting material, which is then allowed to deposit on a workpiece, or substrate as it is usually known. Low pressure is [...] Posted in Charged Particle Devices,How to...

EUGM 2017: Finite element modelling of high frequency gap loss in nanocrystalline inductor cores in Opera-3d

Presenter: Yiren Wang, The University of Manchester Abstract: High-frequency operation is an obvious way to reduce the size of the magnetic components, which typically account for around 50% of the weight of DC-DC converters. However, the losses in the magnetic components tend to increase at high frequencies, in particular some AC losses associated with the […]

EUGM 2017: Simulation of a Pierce Electron Gun with a Maxwell Random Velocity Sampling Emission Model

Presenters: Stephen M. Elliott and Elizabeth K. White, Thin Film Consulting Abstract: We performed validation of a 3d Opera Space Charge simulation of a spherical Pierce gun using the Opera Maxwell Random Velocity Sampling emission model.  Of particular interest is the potential minimum near the space charge limited cathode surface.  We validated the simulation by [...] Posted in Electron Beam Guns,General
