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

Simulation of the H-injection system for the CERN Proton Synchrotron Booster in Opera-3d

Presenter: Jonathan Speed, CERN Abstract: The simulation of magnets for CERN particle accelerators is an essential part of the design process of new units, the analysis of the functionality of old ones, and even to guide the identification of magnet faults. One such application is the analysis of the future H- injection system for the [...] Posted in Accelerator Magnets,General

How to simulate superconducting corrector coils in accelerator magnets

By Chris Riley  Welcome to this blog on modelling superconducting corrector coils with OperaFEA simulation software. We will start with a little bit of history.  The Opera software has links back to the Rutherford laboratory’s Computer Applications Group that began developing computer methods for the design of particle accelerator magnets in the late 1960s. The [...] Posted in Accelerator Magnets,Confinement Coils,Gradient Coils,How to...,Superconducting Magnets,Superconductivity Papers

Webinar: Superconducting corrector coils in accelerator magnets

In this webinar we demonstrated a model to correct a quadrupole magnet that includes a manufacturing error.  We showed how Opera’s coupled transient electromagnetic and circuit simulation can be used to model both ramping up and stable operation. We examined various configurations of the coil and demonstrated the importance of minimizing the effect of higher [...] Posted in Accelerator Magnets,Magnets,Superconducting Magnets

Co-simulation of a pulsed septum magnet and control circuit

Introduction Particle accelerators, such as the Large Hadron Collider (LHC) at CERN, make use of dipole magnets to steer the particle beam. The field is essentially unidirectional between the magnet poles and its interaction with the orthogonal particle beam causes the beam to bend. Many of these magnets are operated with dc current to maintain […]

Optimizing a Quadrupole Magnet

In this example the Optimizer is used with Opera-3d to optimize the performance of a quadrupole magnet used in charged particle beam lines. Auto-optimisation tools are not new, but they usually require manual intervention if a globally-optimal solution is to be found. And simulation times often make such a process impractical. A new tool – […]
