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 [...] Posted in How to...,X-Ray Tubes

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 [...] 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

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, [...] Posted in General

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 [...] Posted in How to...,Induction Machines,Motors

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 vitality in rare earth PM prices and the unavoidable losses in IM’s have renewed interest in SynchRels – especially for [...] Posted in Motors,Synchronous Machines
