Simulation study of n-XYTER front-end electronics in overflow situations for early prototyping of detectors in the CBM experiment — •Tomas Balog — GSI Darmstadt

In high-rate experiments a situation can occur in which the data rate temporarily exceeds the available bandwidth. With self-triggered front end electronics such overload situations would lead, without further measures, to uncontrolled data losses and potentially large number of incomplete events. Mechanisms needed to control data losses and to ensure complete events can be understood using simulations performed by the hardware description language SystemC. Simulations of a simplified n-XYTER based front-end electronics are presented that give first insight in the behaviour of data flow and data losses in the DAQ system of the CBM experiment.
