Apparent universality of spectra as an artifact of finite-size effects
M. A. Korzeniowska, A. Theodorsen, M. Rypdal +1
Power spectral density scaling with frequency as and is widely found in natural and socio-economic systems. Consequently, it has been suggested that such s…
Strongly intermittent far scrape-off layer fluctuations in Alcator C-Mod plasmas close to the empirical discharge density limit
Sajidah Ahmed, Odd Erik Garcia, Adam Q Kuang +3
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 Langmu…
Stochastic modelling of blob-like plasma filaments in the scrape-off layer: Theoretical foundation
J. M. Losada, A. Theodorsen, O. E. Garcia
A stochastic model is presented for a super-position of uncorrelated pulses with a random distribution of amplitudes, sizes, velocities and arrival times. The pulses are assumed to…
Deviations from spectral Dirac comb due to semiperiodic pulses
Audun Theodorsen, Gregor Decristoforo, Odd Erik Garcia
In the frequency power spectral density, periodic oscillations appear as a Dirac comb at integer multiples of the frequency of the period. In weakly nonlinear systems or systems cl…
Numerical turbulence simulations of intermittent fluctuations in the scrape-off layer of magnetized plasmas
Gregor Decristoforo, Audun Theodorsen, John Omotani +2
Intermittent fluctuations in the boundary of magnetically confined plasmas are investigated by numerical turbulence simulations of a reduced fluid model describing the evolution of…
Comparison between mirror Langmuir probe and gas puff imaging measurements of intermittent fluctuations in the Alcator C-Mod scrape-off layer
R. Kube, A. Theodorsen, O. E. Garcia +3
Statistical properties of the scrape-off layer (SOL) plasma fluctuations are studied in ohmically heated plasmas in the Alcator C-Mod tokamak. For the first time, plasma fluctuatio…
