TL;DR: An adjustable permanent magnet quadrupole has been developed for the final focus (FF) in a linear collider as mentioned in this paper, which was used to demonstrate the strongest field gradient at a smaller bore diameter of 15 mm.
Variable permanent magnet sextupole lens for focusing of pulsed cold neutrons
Yoshihisa Iwashita,Y. Tajima,M. Ichikawa,Shu Nakamura,Takashi Ino,Suguru Muto,Hirohiko M. Shimizu +6 more
TL;DR: In this article, a Variable Permanent Magnet Sextupole (VPMS) lens that can focus pulsed slow neutrons is presented, which is based on the extended Halbach configuration to generate stronger magnetic field.
