Astrophysical plasma jets have been observed to emanate from a wide variety of sources on extremely diverse spatial scales. Various mechanisms have been employed in an attempt to explain the formation, acceleration, collimation, and stability of these outflows. Many favor magneto-hydrodynamic (MHD) mechanisms for reasons including the observance of strong magnetic fields in the flows, the recognized ability of the MHD pinch effect to collimate plasma, and the efficiency with which rotational energy can be extracted by magnetic fields. Several theoretical models have been developed to explain the acceleration and collimation of the jets; however, no experimental verification of these theories exists. The CPS-1 (Coaxial Plasma Source) facility at NCSU is capable of producing high conductivity, high enthalpy magneto-flows in a freely varied applied magnetization. This device was designed to provide a convenient means of examining the interaction of a variety of magnetofluid flows (rotating and axial) with applied and self magnetization under controlled laboratory conditions. Recent investigation of these laboratory flows has demonstrated remarkable flow regime and topological similarity with astrophysical jets. In this paper, we will present recent findings from our experimental efforts and a comparison with existing MHD theories of magnetized outflows from galactic nuclei.
