Nov. 499/2 Extra dipoles, sextupoles and octupoles act as correcting magnets in case of defects in the magnet lattice and for superfine control. 1979 Sci. Amer. May 64/1 The atoms emerge from a nozzle as a low-energy beam, then pass into the strongly nonuniform field of a sextupole, or six-pole, magnet... It discriminates strongly between spin-up and spin-down electrons. |
