First results in studying the readout electronics of the silicon tracking system for upgrading the CLAS12 experiment

Investigations of the readout electronics for the tracking system of the CLAS12 experiment have been performed for the last 2 years. The setup and physical problems of the CLAS12 experiment are described. The silicon detectors designed by the authors for the tracking system of the experiment are considered in brief. The electronic system contains the silicon microstrip detector and FSSR2 integrated circuit, which reads signals from the detector. The FSSR2 chip is described and the principles of the chip architecture intended for processing a time-variable data flow and experimental characteristics obtained on trials of the chip are set forth in brief. Results of simulating the chip throughput under loads expected for the physical experiment and experimental characteristics obtained on trials of this chip are described.
