Abstract

The edge turbulence in TFTR is characterized by several diagnostics. Langmuir probes and D-alpha imaging have detected large amplitude, small-scale, broadband density fluctuations in the scrape-off region near the wall. Broadband fluctuations with a similar frequency spectrum are detected by small-angle microwave scattering and magnetic pickup loops. Increases in the turbulence level are seen during neutral beam injection. Some preliminary analysis of this data is presented.
