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, Phys.org 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 [...]


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 [...]


Hyperloop One finishes first phase of testing


Hyperloop One has privately conducted the first tests for its low resistance transport system in full vacuum conditions, Machine Design reports. The tests, which were carried out at low speeds on 12 May, were designed to validate the mag-lev technology and tube vacuum conditions. A bare sled was sent along the company’s DevLoop electromagnetic track, [...]


Stephen M. Elliott of Thin Film Consulting discusses his use of Opera FEA


In this short video Stephen M. Elliott of Thin Film Consulting discusses his use of Opera FEA Simulation Software over his distinguished career. During his career, Stephen M. Elliott has worked on the development of very high voltage generators, ion beam sources, electron guns, linear accelerators, field effect emitting devices, pulsed high current systems, magnetron [...]


Marcel Kruip of Tokamak Energy discusses his use of Opera FEA


In this short video Marcel Kruip discusses his use of Opera FEA Simulation Software at Tokamak Energy. Tokamak Energy was established in 2009 to design and develop small spherical tokamaks to produce neutrons for a range of scientific applications. In 2012, with the emergence of high temperature superconductor materials in a form suitable for winding [...]

Colin is a physicist working as a Technology Consultant at TWI, a Cambridge based engineering consultancy. His role is in the design of electron guns, lenses and deflection systems for industrial applications such as X-ray [...]


Transient Simulation of the ISIS Synchrotron Singlet Quadrupoles using Opera-3d


Authors: I. Rodriguez* , ISIS, Rutherford Appleton Laboratory, STFC, Didcot, UK Abstract: Type QX106 singlet magnets are AC defocusing quadrupoles used in the ISIS main synchrotron ring. They have an aperture of 202 mm and a yoke length of 303 mm, so the end effects are significant. The iron poles and the yoke are asymmetric [...]


How to design an induction machine


The Induction Machine (IM) is the most widely used type of electrical machine. By some estimates it accounts for 90% of all small size motors (10 – 750W) and 60 -70% of medium size motors (0.75 – 375 kW). This is mainly due to their reliability, low cost and wide range of torque / speed [...]


Optimisation of Synchronous Reluctance Motors (SynchRels) using Opera


In the last few decades, the synchronous reluctance motor (SynchRel) has been relatively neglected in industrial, domestic and traction application because of the ascendency of permanent magnet (PM) and the ubiquitous induction (IM) motor. Recent volatility in rare earth PM prices and the unavoidable losses in IM’s have renewed interest in SynchRels – especially for [...]
