  The first laboratory astrophysics experiments to produce a radiatively cooled
plasma jet with dynamically significant angular momentum are discussed. A new
configuration of wire array z-pinch, the twisted conical wire array, is used to
produce convergent plasma flows each rotating about the central axis. Collision
of the flows produces a standing shock and jet that each have supersonic
azimuthal velocities. By varying the twist angle of the array, the rotation
velocity of the system can be controlled, with jet rotation velocities reaching
~20% of the propagation velocity.
