The recently reconstructed focal plane detector system for the gas-filled recoil separator RITU was used to observe a new proton emitter ¹⁶⁴Ir. The nuclide was produced via the p5n fusion evaporation channel using a ⁶⁴Zn beam on a ¹⁰⁶Cd target. The proton energy E_p = 1817(9) keV and half-life T_1/2 = 113⁺⁶²_-30 \mu s were used to characterize the decaying state to be [\pi h_11/2 \nu f_7/2]9⁺. The new focal plane detector system and the results of the proton decay studies will be discussed.
