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 [...] Posted in Magnets,Plasma Discharge

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 [...] Posted in Confinement Coils,Gradient Coils,Magnets,Magnets Paper

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 [...] Posted in Magnets,Magnets Paper,MRI / NMR Magnets

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 [...] Posted in General,Magnets,Magnets Paper

CERN and LHC-AUP developing quadrupole magnets

The Large Hadron Collider (LHC) is set to be upgraded to the High-Luminosity LHC and this will require over one kilometre of the machine needing to be replaced, recently discussed. Installation isn’t set to begin until 2024 but scientists and engineers around the world are already starting to develop the new magnets that will [...] Posted in Accelerator Magnets,General,Magnets

First low-energy particle accelerator beam created in the US

The first low-energy particle accelerator beam has been created by nuclear astrophysicists underground in the US, the University of Notre Dame reports. The aim of the project, called CASPAR (Compact Accelerator System for Performing Astrophysical Research), is to gain a better understanding about how stars burn and what elements they create while doing so. The [...] Posted in Accelerator Magnets,General

How to design for MRI magnets

In this blog we’ll look at the design of shielding for a known MRI magnet, but also at the solution to developing a model of the magnet when only fringe-field maps are available. The basic ground-work of what has become known as MRI was laid in the 1950’s but it wasn’t until the 1970’s that [...] Posted in How to...,Magnets,Magnets Paper,MRI / NMR Magnets
