How to design for x-ray tube


In this blog we will look at the utility of the Opera simulation environment for the simulation of X‑ray tubes. Firstly, we will concentrate on their operation and design parameters, and the requirements that these place on tools used in their design. We’ll follow this with look at the capability of Opera to meet these [...]


NAUGM Conference 2017


On September 26-27, 2017, Cobham Technical Services hosted this year’s North American User Group Meeting at the Hilton Lisle/Naperville located in Lisle, IL. This year a wide range of interesting and inspiring oral presentations were given by users with extensive knowledge of the software.  Attendees consisted of both newcomers as well as veteran users, giving them [...]


Using Opera for Fusion Energy Applications


In this webinar we showed examples of fusion design calculations using Opera, and demonstrated 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 within the vacuum vessel is important for safety. We'll [...]


A Pulsed Magnet System for a Field-Reversed Configuration Experiment


Authors: Dennis W. Lieurance, David D. Madura, and Gregory L. Snitchler, Member, IEEE Abstract: From a magnet engineering perspective, the field-reversed configuration (FRC) fusion concept is commercially attractive due to its cylindrical configuration. Essentially, all large coils are solenoidal, which enables efficient structural support and relative ease of manufacturing, thereby enhancing commercial viability. A design [...]



MRI Shielding Optimization in Opera – 15 minute overview


In this 15-minute presentation we show the benefits Opera Optimizer offers when used in conjunction with magnetostatic analysis for MRI shielding applications. We also demonstrate the benefits of the new “thin plate” boundary condition, which increases efficiency without compromising accuracy, and how Opera provides the ability for MRI shielded room designers to customize the Modeller [...]


NDT Device Design in Opera – 15 minute overview


Non-destructive testing or evaluation (NDT or NDE) is a process used in industry to evaluate properties of a material or a system without damaging it. Some of the uses of NDT are flaw detection and evaluation, leak detection, location determination, dimensional measurements, structure and Microstructure characterization, estimation of mechanical and physical properties, stress (strain) and [...]


Magnetic Signature Identification using Pareto optimization


Christopher Riley, Engineering Manager, Cobham Technical Services Abstract Determining the topology of a naval vessel from its measured magnetic signature is a classic inverse problem – what is the source of the observed response? This paper explores an alternative to classical inverse methods with a technique that is used in design optimization. Pareto optimization is [...]


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 [...]
