MiniSPD testing facility

Abstract

MiniSPD is an installation for cosmic muon tests of all types of detectors to be used in the Spin Physics Detector (SPD) setup. The detectors and readout electronics for the NA64 experiment were used for testing. The MiniSPD setup includes the scintillator-based trigger system, straw, silicon, and Gas Electron Multiplier (GEM) tracking detectors, electromagnetic calorimeter, and the lead filter to remove the low-energy component of cosmic rays. The MiniSPD setup was used to measure such important parameters of detector prototypes and subsystems as the spatial and time resolution, efficiency, drift characteristics, amplification, data acquisition parameters, slow control implementation, and online monitoring systems features.
