New Spinor Field Realizations of the Non-Critical W₃ String

We investigate the new spinor field realizations of the W₃ algebra, making use of the fact that the W₃ algebra can be linearized by the addition of a spin-1 current. We then use these new realizations to build the nilpotent Becchi--Rouet--Stora--Tyutin charges of the spinor non-critical W₃ string.
