Abstract: The TOF-ScintillatorRingdetector is part of the Time-of-Flight Spectrometer TOF which is an external experiment at the Cooler Synchrotron COSY in Jülich. With this detector, the reactions of proton to proton and proton to deuteron interaction is studied via detection of velocities and direction of the loaded particles. The TOF experiment consists of a vacuum vessel which is filled with scintillator counters. The proton beam enters the system hitting a target. With some very thin scintillator counters arranged directly behind that target and further counters mounted on the wall of the vessel the direction and the velocity of loaded reaction products can be measured scanning a huge angle spectrum. This report focuses less on the nuclear physics but on the manufacturing, fixing and mounting of the ring detector. The vacuum vessel has, dependent on the experimental set-up, a length of up to 9850 mm and a diameter of 4000 mm. The ringdetector is composed by three scintillators levels, one following the other and each 5 mm thick. 192 szintillator strips are needed; on each end a light conductor is glued. The scintillator strips are fixed in the vacuum vessel by a special device made of carbon. The fixation consists of a winded carbon wheel hub and twelve carbon spokes, which do center and position the wheel hub
