The stability of the spheromak against low n (n = 1, 2, 3, 4, 5) and localized modesis investigated by use of ERATO-J code and by means of the Mercier criterion. Heren is the toroidal mode number. The shape of the plasma is assumed to simulate the ex-perimental plasma in the flux conserver of CTCC-II at Osaka University. The betalimits for these modes are evaluated as a function of q.., to elucidate which modegives a lower limit. Here q.., is the value of the safety factor on the magnetic axis. Asa result, the beta limit of the spheromak is shown to be determined by the n = 1, then=2 and the localized modes. However, the Mercier criterion is shown to give anexcellent measure for the stability against internal modes, if q....<0.9.[spheromak, Ml-10 stability, ERATO-J code, high temperature plasma, ther- ll monuclear fusionl
