1. Divertor & SOL Characterisation with Visible Imaging
Filamentary transport imaged in the MAST divertor using a fast framing camera
Filaments observed in the SOL and private flux region
Extent of fluctuating regions different in L-mode and H-mode
Flow of C2+ ions measured using Doppler coherence imaging
Spatial resolution <1cm, flow resolution ~1km/s
C2+ ions ~2x faster in outer divertor leg after L-H transition
Carbon ions accelerate to deuterium sound speed near target
High-speed imaging
Coherence imaging of C2+ flows
CIII Line Intensity
CIII Parallel Flow
