摘要：

Experimental evidence is presented demonstrating that an ion cyclotron resonance heating (ICRH) beatwave can drive toroidicity induced Alfven eigenmodes (TAEs) to a finite amplitude and also increase the amplitude of TAEs already excited by fast ions. The radial structure of a beatwave driven TAE reconstructed from soft x-ray measurements is shown to agree with simulations from the gyro-kinetic code LIGKA. Thus beatwaves provide the means to excite TAEs which can be used to diagnose the plasma's safety factor profile through MHD-spectroscopic techniques without significantly perturbing the plasma or to influence the stability of existing TAEs allowing their effect on the fast ion population to be studied.
