Halbach Magnets for CBETA and eRHIC
2017At Brookhaven National Laboratory two design efforts are underway: eRHIC and CBETA. eRHIC is a proposed upgrade to the existing Relativistic Heavy Ion Collider (RHIC), which would allow collisions of up to 21 GeV polarized electrons with protons or heavy ions. CBETA is a 150 MeV electron accelerator, aiming to demonstrate essential technology necessary

Modelling and Analysis of the Halbach Array Magnets
2019 11th International Symposium on Advanced Topics in Electrical Engineering (ATEE), 2019The objective of this paper is the implementation through numerical modelling of Halbach permanent magnets for the determination of the optimum magnetization directions in order to obtain a uniform magnetic field around the set of Halbach permanent magnets. For this study the magnetic induction distribution, magnetic field intensity and current density

Optimization of the Superconducting Halbach Array
2020This Chapter presents the further optimization of the coil locations and the number of coils, to obtain a better homogeneity of the magnetic field in the centre area of the superconducting Halbach Array, on the premise of maintaining the total amount of superconducting material used.

A concept for an MPI scanner with Halbach arrays
2020One of the major challenges of MPI is the upscaling of scanners. Typically, the magnetic fields are generated electromagnetically with immense power consumption, which becomes a severe issue for larger setups. However, electromagnets provide high flexibility in terms of adjusting the gradient strength of the selection field and providing quickly ...

Klaus Halbach, Undulator Pioneer
Synchrotron Radiation News, 2015I am indebted to Karl Brown for suggesting that I invite Klaus, who I did not know at the time, to a workshop on wiggler magnets in March 1977. I recall Karl saying to me something like, “Herman, if you want someone who knows about magnets, you should invite Klaus Halbach.” Klaus came and even made a contribution about some aspects of the design of ...

Halbach Array for an in- Wheel Traction Motor
2018 XIII International Conference on Electrical Machines (ICEM), 2018This paper compares a Halbach array to a more conventional surface mounted permanent magnet arrangement for an in wheel traction motor. Demagnetisation, physical air-gap and torque capability at continuous and overload operation is considered. Without increasing the machine operating space, using one transition per pole was found to increase rated ...

Bearingless segment motor with Halbach magnet
SPEEDAM 2010, 2010Today magnetically levitated rotors are mainly used in applications where wearless operation and high life cycle are of importance (e.g. in the pharmaceutical, biomedical, chemical and semiconductor industry). The bearingless slice motor features a very compact design because three degrees of freedom (one translational and two rotatory) are passively ...
