CALLISTO can be found at the "Gesellschaft für Schwerionenforschung", GSI, near Darmstadt/ Germany.

CALLISTO can hardly be moved to another location, because the special target chamber, which is part of CALLISTO, can be used efficiently only at GSI. Much of CALLISTO was built at GSI with the support of the Nuclear Chemistry Group.

Major parts of CALLISTO were made at the “Institut für Kernchemie” of the Johannes-Gutenberg- University Mainz.
