The main detector system used for this purpose is the Start-Veto system which consists of two diamond based sensors made of pcCVD and scCVD diamond materials. Both sensors are equipped with a double-sided strip segmented metallization (300 µm width) which allows a position determination of the beam. Those sensors are able to deliver a time precision <100 ps and can handle rate capabilities up to 10⁷ particles/s/channel. Beside the diamond sensors a plastic scintillation based beam halo detector is used. The read-out of the detectors is based on the TRB3 system*. A 264 channel TDC (Time to Digital Converter) is implemented in FPGA technology with 10 ps precision. The TRB3 system serves as a fast and flexible Data Acquisition System (DAQ) with integrated scaler capability. The analysis and online visualization is performed using the Data Acquisition Backbone Core (DABC)** framework. In this contribution the performance of the system, which was used in order to evaluate an Ar and Ag ion beam delivered by the SIS 18 accelerator, will be discussed.
