Intermittent fluctuations in the TCV scrape-off layer

Probe measurements in the scrape-off layer of tokamak plasmas show that the ion saturation current signal is dominated by large amplitude bursts. Analysis of data time series from tokamak á configuration variable of unprecedented duration reveals that both burst amplitudes and waiting times are exponentially distributed. The average burst wave form has an exponential shape with a characteristic...

Scrape-Off Layer physics in limited plasmas in TCV

Controlled nuclear fusion is the most promising candidate for being an inexhaustible, clean and intrinsically safe energy source. Research in the last 60 years has focused on the fusion reactor concept called tokamak, in which a high temperature plasma is confined using magnetic fields, producing fusion reactions. Because of turbulence, the confined plasma diffuses to the outermost region of th...
