This new wave scattering phenomenon is shown to be related to the passage of the O point of a magnetic island through the high power heating beam. The density determines the detailed phasing of the scattered radiation relative to the O-point passage. The scattering power depends strongly nonlinearly on the heating beam power.}, year = {2009}, journal = {Physical Review Letters}, volume = {103}, number = {12}, pages = {4}, month = {Sep}, isbn = {0031-9007}, url = {://000270139000030 }, note = {ISI Document Delivery No.: 498KOTimes Cited: 0Cited Reference Count: 22}, language = {English}, }
