We have investigated the evolution of the turbulence generated by a vibrating wire resonator driven at high velocities and temperatures down to -0.1T(c). The vibrating wire produces vorticity together with the expected quasiparticle beam whenever the wire velocity exceeds the critical pair breaking velocity. By using an array of detector wires we are able to investigate the development of the turbulence both in space and time.
