High resolution density pedestal measurements during edge localized modes by short-pulse reflectometry in the TCV tokamak
Stefano Coda, Benoît Labit, Laurie Porte, Pedro Andres Molina Cabrera
This publication presents high spatio-temporal resolution (mm/μs) density profile measurements of the pedestal top during type I, III, and small edge localized mode (ELM) H- mode plasmas in the Tokamak à Configuration Variable (TCV). These measurements wer ...
2021Tokamak plasma edge studies by microwave short-pulse reflectometry and backscattering
Moving towards an increased understanding of the dynamic processes in the edge of
tokamak plasmas requires continuous innovation in diagnostic capabilities, pushing the
envelope in both spatial and temporal dimenstions. Plasma density and rotation, and
the ...
EPFL2019V-band nanosecond-scale pulse reflectometer diagnostic in the TCV tokamak
Stefano Coda, Laurie Porte, Pedro Andres Molina Cabrera
This article describes the realization of a novel approach to short pulse (∼1 ns) reflectometry (SPR) recently implemented in the tokamak configuration variable tokamak. Taking advantage of a fast arbitrary waveform generator and vector-network-analyzer ex ...
2019V-band Doppler backscattering diagnostic in the TCV tokamak
Stefano Coda, Laurie Porte, Matthieu Toussaint, Pierre Lavanchy, Pedro Andres Molina Cabrera, Nicola Offeddu
A variable configuration V-band heterodyne Doppler back-scattering diagnostic has been recently made operational in the tokamak a configuration variable. This article describes the hardware setup options, flexible quasi-optical launcher antenna, data-analy ...
AMER INST PHYSICS2018PLASMA SHAPE AND FUELING DEPENDENCE ON THE SMALL ELMS REGIME IN TCV AND AUG
Benoît Labit, Antoine Pierre Emmanuel Alexis Merle, Umar Sheikh, Pedro Andres Molina Cabrera, Roberto Maurizio
A series of experiments has been conducted at AUG and TCV to disentangle the role of fueling, plasma triangularity and closeness to a double null (DN) configuration for the onset of the small ELM regime. At AUG, the role of the SOL density has been revisit ...
