Quadrupole magnet - Wikipedia
Quadrupole magnets, abbreviated as Q-magnets, consist of groups of four magnets laid out so that in the planar multipole expansion of the field, the dipole terms cancel and where the …
So far we have derived the B fields for two types of magnets (dipole and quadrupole). It would be very useful for us to have a general expression to represent the B field of any magnet. …
The magnetic field in the quadrupole is B′yxˆ +B′xyˆ, where B′ is a constant characteristic of the particular quadrupole magnet. Derivation of this field will follow
Quadrupole - Wikipedia
The quadrupole moment tensor Q is a rank-two tensor—3×3 matrix. There are several definitions, but it is normally stated in the traceless form (i.e. + + =).The quadrupole moment tensor has …
Research on a novel permanent quadrupole magnet (PQM) design is introduced in this paper. It can make the quadrupole magnetic field gradient continuously adjusta-ble by modulating …

The large magnet blocks shown in Fig. 1 will be split into carriages containing arrays of smaller magnets in order to ease the handling of the permanent magnet material.
The method we used to determine the magnetic centers of the quadrupoles, as well as to map the field in x, y, and z, was to insert a rotating coil into the field and to use the induced EMF in the …
This paper presents an innovative compact permanent magnet quadrupole with a strong gradient for potential use in future light source lattices. Its magnetic structure includes simple …
