FATIMA - A DATA ACQUISITION-SYSTEM FOR MEDIUM SCALE EXPERIMENTS

The data acquisition system FATIMA (Fera Amplitude and TIme Multiparameter Analyzer) utilizing CAMAC, FERA [1] and a VAX-Station has been designed and built for nuclear physics experiments like subthreshold pi-0-production in Heavy Ion Collisions. The major features of the system are fast data readout of up to 352 ADCs and/or TDCs in conjunction with data reduction, event buffering, high speed data transfer and simple interfacing to any workstation. For on-line acquisition, recording and analysis of data as well as experiment control a modular program system was developed on VAX/VMS. Data analysis comprises on-line sort of real and pseudo channels and graphical representation of sorted data.
