• A new toroida[ Z pinch device ZP-2 has been constructed and low plasma current(<25 kA) experiments have been carried out. An axisymmetric force free field configuration of the pinch parameter 0 of 1.3 to 1.4 is successfully established from spon-taneous generation of toroidal field flux and is sustained for nearly 100 7ts. During thesetting up phase, local toroidal fields accompanied with m = l perturbations are pro-duced, and develop to local toroidal field flux and global toroidal field flux. Axialasymmetry results in toroidal rotation of the plasma and the configuration is axiallysymmetrized. During the sustainment phase (2=constant), field flux discretely in-creased together with the plasma current. Termination of the configuration resultsfrom decay of loop voltage and is accompanied with appearance of axial asymmetryon field flux.
