The muon-catalyzed fusion (μ CF) process in tritium was studied by the μ CF collaboration on the muon beam of the JINR Phasotron. The measurements were carried out with a liquid tritium target at the temperature 22 K and density approximately 1.25 of the liquid hydrogen density ( LHD). Parameters of the μ CF cycle were determined: the ttμ muonic molecule formation rate λ_ttμ=2.84 (0.32) μs^-1, the tt fusion reaction rate λ_f=15.6 (2.0) μs^-1, and the probability of muon sticking to helium ω_tt=13.9 (1.5) %. The results agree with those obtained earlier by other groups, but better accuracy was achieved due to our unique experimental method.
