- Abstract:
  A module with a double-sided microstrip silicon sensor is the basic element of the silicon tracking system (STS) for the BM@N experiment. The signal-to-noise ratio is the main parameter of the tracking system for a high-energy physics experiment, which is determined by the complex influence of the parameters of the detector and the front-end electronics. An analytical model of various noise sources is presented, and parameters determining the efficiency of charge collection from the detector are discussed. The noise has been measured for several module configurations differing in the sensor size and the length of the signal cable connecting the sensor strips to the input circuits of the front-end electronics. Results of measurements of the signal from a 106Ru β-source are presented. It is shown that the signal-to-noise ratio for STS modules is at least 18. [ABSTRACT FROM AUTHOR]
