Gas puff imaging (GPI) is a diagnostic of plasma turbulence which uses a puff of neutral gas
at the plasma edge to increase the local visible light emission for improved space-time …

The transport of particles and energy into the scrape-off layer (SOL) region at the outboard
midplane of medium-sized tokamaks, operating in low confinement mode, is investigated by …

Abstract The Alcator C-Mod mirror Langmuir probe system has been used to sample data
time series of fluctuating plasma parameters in the outboard mid-plane far scrape-off layer …

A stochastic model for a superposition of uncorrelated pulses with a random distribution of
amplitudes, sizes, and velocities is presented. The pulses are assumed to move radially with …

Statistical properties of the scrape-off layer plasma fluctuations are studied in ohmically
heated plasmas in the Alcator C-Mod tokamak. For the first time, plasma fluctuations as well …

The impact of positive and negative edge biasing on the interchange plasma turbulence in
the edge and scrape-off layer (SOL) regions of a tokamak is assessed by comparing …

The formation of a density blob in the boundary region of a tokamak plasma is widely
believed to be due to the presence of poloidal velocity shear that differentially breaks off a …

Anomalous plasma transport in the boundary region of a tokamak plasma is commonly
associated with the formation and evolution of coherent density structures known as blobs …

To investigate blob properties in the tokamak scrape-off layer (SOL), we perform dedicated
numerical nonlinear simulations of plasma turbulence in the SOL of a TCV discharge using …

Intermittent plasma fluctuations in the boundary region of the Alcator C-Mod device were
comprehensively investigated using data time-series from gas puff imaging and mirror …
