Description
By using a set of pick-up coils positioned around the minor circumference of the discharge tube, the stability behaviour of the screw-pinch plasma in SPICA is studied. The data-processing system, AD-converters combined with a conputer, enables us to treat a large number of signals. The signals from the pick-up coils are transferred to the computer and are expanded into a Fourier series. The m = 1 cosine oscillation in the rise phase suggests a screw-pinch model in which a plasma core is surrounded by a current layer and a vacuum region. An m = 2 deformation is found to correlate with the decay rate of the plasma current
