主　　题：Sawtooth Plasmas HL 1M 

摘      要：Sawtooth stabilization is one of the attractive topics in Tokamak research because sawtooth oscillations always lead to central confinement degradation although it can ejects impurity particles from the plasma center. The sawtooth-free, e. g. sawtooth-stabilized, plasma have been obtained in ASDEX with LHCD, in JET with ICRH and pellet injection. Earlier than these, sawtooth-free plasmas have been observed in Doublet Ⅲ ’0’ type discharge and then in ASDEX ohmic
