Abstract

A simulator of data frames produced by 'multi-accumulation' readout detectors has been developed during the feasibility study for the NIS spectrograph, part of the European Euclid mission. The software can emulate various readout strategies, allowing to compare the efficiency of different sampling techniques. Special care is given to two crucial aspects: the minimization of the noise and the effects produced by cosmic hits. The resulting readout noise is analyzed as a function of the background sources, detector native characteristics and readout strategy, while the image deterioration by cosmic rays covers the simulation of hits and their correction efficiency varying the readout modalities. Simulated "multi-accumulation" frames, typical of multiplexer based detectors, are an ideal tool for testing the efficiency of cosmic ray rejection techniques. In the present case cosmic rays are added to each raw frame conforming to the rates and energy expected in the operational L2 region and in the chosen exposure time. Procedures efficiency for cosmic ray identification and correction can also be easily tested in terms of memory occupancy and telemetry rates.
