Radial localization of edge modes in Alcator C-Mod pedestals using optical diagnostics

Christian Gabriel Theiler

Dedicated experiments in ion cyclotron range heated enhanced D-alpha (EDA) H-mode and I-mode plasmas have been performed on Alcator C-Mod to identify the location of edge fluctuations inside the pedestal and to determine their plasma frame phase velocity. ...

Scrape-Off Layer physics in limited plasmas in TCV

Federico Nespoli

Controlled nuclear fusion is the most promising candidate for being an inexhaustible, clean and intrinsically safe energy source. In the tokamak fusion reactor concept, a high temperature plasma is confined by magnetic fields. Turbulence diffuses the confi ...

A comparison between a refined two-point model for the limited tokamak SOL and self-consistent plasma turbulence simulations

Paolo Ricci, Christoph Wersal, Joaquim Loizu Cisquella

A refined two-point model is derived from the drift-reduced Braginskii equations for the limited tokamak scrape-off layer (SOL) by balancing the parallel and perpendicular transport of plasma and heat and taking into account the plasma–neutral interaction. ...

Poloidal CX visible light plasma rotation diagnostics in TCV

Claudio Marini

Controlled thermonuclear fusion is the main goal of plasma physics. At the Swiss Plasma Center, the Tokamak `a Configuration Variable (TCV) constitutes the main experiment on fusion research, where high temperature plasmas are confined by means of magneti ...

Multi-code analysis of scrape-off layer filament dynamics in MAST

Paolo Ricci, Fabio Riva

Four numerical codes are employed to investigate the dynamics of scrape-off layer filaments in tokamak relevant conditions. Experimental measurements were taken in the MAST device using visual camera imaging, which allows the evaluation of the perpendicula ...

Oxygen Displacement in Cuprates under Ionic Liquid Field-Effect Gating

Davor Pavuna, Guy Joseph Günter Dubuis, Ivan Bozovic, Xi He

We studied structural changes in a 5 unit cell thick La1.96Sr0.04CuO4 film, epitaxially grown on a LaSrAlO4 substrate with a single unit cell buffer layer, when ultra-high electric fields were induced in the film by applying a gate voltage between the film ...

The GBS code for tokamak scrape-off layer simulations

Paolo Ricci, Joaquim Loizu Cisquella, Trach-Minh Tran, Sébastien Jolliet, Federico David Halpern, Fabio Riva, Annamaria Mosetto, Christoph Wersal

We describe a new version of GBS, a 3D global, flux-driven plasma turbulence code to simulate the turbulent dynamics in the tokamak scrape-off layer (SOL), superseding the code presented by Ricci et al. (2012) [14]. The present work is driven by the object ...
