A fragment separator is an ion-optical device used to focus and separate products from the collision of relativistic ion beams with thin targets. Selected products can then be studied individually. Fragment separators typically consist of a series of superconducting magnetic multipole elements. The thin target immediately before the separator allows the fragments produced through various reactions to escape the target material still at a very high velocity. The products are forward-focused because of the high velocity of the center-of-mass in the beam-target interaction, which allows fragment separators to collect a large fraction (in some cases nearly all) of the fragments produced in the target. Some examples of currently operating Fragment separators are the FRS at GSI, the A1900 at NSC
