Abstract
A CO.sub.2 nozzle receives and expels liquid CO.sub.2 through orifices sized for converting the CO.sub.2 liquid into CO.sub.2 snow. A body, defining an elongated cavity therein, is coupled to the CO.sub.2 nozzle such that the CO.sub.2 snow is ejected into the cavity. An exhaust nozzle is coupled to the body and the cavity therein for directing the pressurized CO.sub.2 snow toward the workpiece. The exhaust nozzle is operated in an overexpanded mode for containing the shockwave within the nozzle for reducing the shear noise therefrom. Pressurized air is injected into the elongated cavity for exhausting the CO.sub.2 snow under pressure.
