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

Superconductivity for accelerators for medical applications

CIEMAT, in collaboration with HEPTech, EUCARD2, CDTI, GSI and EEN recently held a workshop on “Superconductivity for accelerators for medical applications”. In our everyday environment, compact superconducting accelerators produce short-life radionucleides to make diagnoses and proton and ion beams to treat tumours by hadrontherapy. Superconductivity has become a key technology of particle accelerators, helping their […]

Design and Optimization of Superconducting MRI Magnet Systems with Magnetic Materials

Authors: Tony Tadic and B. Gino Fallone Medical Physics Department, Cross Cancer Institute, Edmonton, Canada Abstract: We present a method for the optimal design of superconducting magnet systems for magnetic resonance imaging (MRI). The method integrates a linear-programming technique with the finite-element method (FEM) to calculate minimum-volume coil configurations subject to magnetic field homogeneity constraints […]

YBCO conductor technology for high field muon cooling magnets*

Authors: S.A. Kahn, G. Flanagan, R.P. Johnson, M. Turenne, F. Hunte, J. Schwartz Abstract: YBCO superconductors originally developed for high temperature operation carry significant current even in the presence of extremely high field when operated at low temperature. The final stage of phase space cooling for a muon collider uses a solenoid magnet with fields […]
