The Su­per-FRS is a su­per­con­duct­ing frag­ment sep­a­ra­tor that will be built as part of the FAIR fa­cil­i­ty. For the slow-ex­trac­tion part of the beam di­ag­nos­tics sys­tem a total of 32 de­tec­tors are need­ed for beam mon­i­tor­ing and for track­ing and char­ac­ter­i­za­tion of the pro­duced ions. Since GEM-TPC de­tec­tors can per­form over wide dy­nam­ic range with­out dis­turb­ing the beam, they are suit­able for this kind of in-beam de­tec­tion. We have stud­ied the per­for­mance of a pro­to­type GEM-TPC. The cur­rent sta­tus of the pro­to­type de­tec­tor and the mea­sure­ment re­sults are shown.
