Direct mass measurements of short-lived exotic nuclei yield key information for modern nuclear physics. Experimentally determined mass values of exotic nuclei have a big impact on numerous applications in fundamental and applied science. With the Superconducting-Fragment Separator (Super-FRS) at the new FAIR facility a whole new range of exotic nuclei far away from stability will be accessible. Higher beam intensities and larger phase space volumes impose new challenges for the detection systems. To measure masses of short-lived exotic nuclei one can use the Isochronous Mass Spectrometry (IMS)which presently is successfully performed at the FRS-ESR facility. For IMS in the future Collector Ring, (CR) a first version of a new dual Time-Of-Flight (TOF) detector system, which fulfills the requirements of the new beam parameters has been designed. Simulationresults for the new TOF detector in the CR will be shown.
