The electromagnet is the work-horse of the accelerator lab, in that almost all transverse manipulations of charged particle beams are based upon them. Because of our ubiquitous need for these devices, PBPL has over the last decade built up a large program in electromagnet design and production. The design of these devices most often falls upon graduate students, who employ two and three-dimensional magnetostatic modeling codes to produce geometries that yield the desired field profiles.
At the PBPL, solenoids, dipoles, steering magnets, quadrupoles and sextupoles are produced for our laboratory needs in Neptune and PEGASUS. These devices are also employed by our collaborators:
