• A full resistive 3D MID simulation code is developed to examine the pressure-driven instability of a high-beta spheromak in a flux conserver. It is found that thetime evolution of the pressure-driven mode can adequately be investigated by thedeveloped 3D code. Simulations are made for three different beta values. Resultshave shown that a low-n ballooning mode (777=1, n=3) is most strongly excitedfor all beta values. Extrapolation of these results suggests that the beta limit forthis mode is about 5 '7;. With the development of the instability, magnetic sur-faces are observed to be destroyed considerably.
