Particle accelerator systems design at HVE with Opera-3D

Presenter: Guillermo Dominguez, High Voltage Engineering Abstract: Opera-3D has proven to be a valuable design and optimization tool of particle accelerator systems which can presently go up to 6 million volts. We will present recent systems developed at HVE, examples where Opera-3D simulation package has helped improve/optimize the engineering, anticipating the major challenges while shortening [...] Posted in Magnets,Magnets Paper,Superconducting Magnets

Coupled simulation of 400 MHz elliptical cavity with Soprano and Static Stress Solver of Opera

Presenter: Anastasia Xydou, CERN Abstract: The LHC (RF) cavity is a metallic chamber which contains an oscillating electromagnetic field. The cavity is made of copper and the desired superconducting behavior is achieved by sputter-depositing its inner surface with a film of niobium (Nb) with a thickness of the order of 1 m. Each cavity is enveloped [...] Posted in Magnets,Magnets Paper,Superconducting Magnets

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

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

Optimization in Tri-Axial Degaussing System Design

Authors: Vishal Modagekar, Department of Electrical Engineering Veermata Jijabai Technological Institute Matunga, Mumbai 400019, Abdul Karim Shaikh and Navdeep Singh Abstract: Contemporary ships, made of ferromagnetic materials, under the influence of Earth’s magnetic field produce an underwater magnetic anomaly. This anomaly, often called the magnetic signature, compromises the stealth and safety of the ship and needs to be minimized. […]
