Strong focusing
Videos
In accelerator physics strong focusing or alternating-gradient focusing is the principle that, using sets of multiple electromagnets, it is possible to make a particle beam simultaneously converge in
Sextupole electromagnet as used within the storage ring of the Australian Synchrotron to focus and steer the electron beam
Quadrupole electromagnet from the storage ring of the Australian Synchrotron serves much the same purpose as the sextupole magnets.
