Scintillation counters of the muon system at CDF II

The framework of scintillation counters for the CDF II muon system at the Tevatron collider at Fermilab is described. Information from the detectors of the muon system is essential for forming triggers of the first and second levels and for an "off-line" data analysis related to studies in the field of the heavy quark physics, Standard Model tests, search for phenomena beyond its limits, and for many other CDF II experiments with p $\overline{p}$ collisions at the energy √s = 1.96 TeV.
