A Data Acquisition System for Medium Scale Experiments

The data acquisition system FATIMA (FERA amplitude and time multiparameter analyzer), which utilizes CAMAC, FERA (Fast Encoding and Readout ADC System), and a VAX-Station, has been designed and built for nuclear physics experiments like subthreshold pi /sup 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 online acquisition, recording, and analysis of data as well as experiment control a modular program system was developed on VAX/VMS. Data analysis comprises online sort of real and pseudo channels and graphical representation of sorted data. >
