The Fragment Separator is a device for producing and separating exotic
nuclear beams. The exotic nuclei can be investigated directly, or the
secondary beams can be injected into the storage-cooler ring, or deli
vered to targets in the experimental caves. The magnets of the spectro
meter and the equipment used to measure the magnetic fields are descri
bed. Results of the measurements and operational experience with the l
aminated magnets are reported.
