Abstract
In this thesis, a specially-designed detector for use in a state-of-the-art reaction microscope was built and tested. It uses a con guration of a delay-line-anode combined with a Z-stack multichannel plate detector. This detector system will be used to analyze the momentum of all constituent particles in ion-atom-collisions. By irradiating an aperture with -particles, the detector's time and spatial resolution was determined to be approximately 140 ps and < 0; 69 mm, respectively. Due to systematic rst measurement errors, the spatial resolution should be improved by a factor of 3. On the other hand, the detector's dead time has a precision of about 6 ns.
