Observations of core ion cyclotron emission on ASDEX Upgrade tokamak
(American Institute of Physics, 2018)
The B-dot probe diagnostic suite on the ASDEX Upgrade tokamak has recently been upgraded with a new 125 MHz, 14 bit resolution digitizer to study ion cyclotron emission (ICE). While classic edge emission from the low field ...

Assessment of the baseline scenario at q(95) similar to 3 for ITER
(IOP Publishing, 2018-12)
The International Tokamak Physics Activity topical group on integrated operational scenarios has compiled a database of stationary H-mode discharges at q95 ~ 3 from AUG, C-Mod, DIII-D, JET and JT-60U, for both carbon ...

Design and simulation of an imaging neutral particle analyzer for the ASDEX Upgrade tokamak
(American Institute of Physics, 2021-04-26)
An Imaging Neutral Particle Analyzer (INPA) diagnostic has been designed for the ASDEX Upgrade (AUG) tokamak. The AUG INPA diagnostic will measure fast neutrals escaping the plasma after charge exchange reactions. The ...

Investigation of deuterium trapping and release in the JET ITER-like wall divertor using TDS and TMAP
(ELSEVIER, 2019-05-19)
Selected set of samples from JET TER-Like Wall (JET-ILW) divertor tiles exposed both in 20132014 and 20112014 has been analysed using Thermal Desorption Spectrometry (TDS). The deuterium (D) amounts ob tained with TIS were ...

On the role of finite grid extent in SOLPS-ITER edge plasma simulations for JET H-mode discharges with metallic wall
(Elsevier, 2018-12)
The impact of the finite grid size in SOLPS-ITER edge plasma simulations is assessed for JET H-mode discharges with a metal wall. For a semi-horizontal divertor configuration it is shown that the separatrix density is at ...

In situ wavelength calibration of the edge CXS spectrometers on JET
(AIP Publishing, 2016-11)
A method for obtaining an accurate wavelength calibration over the entire focal plane of the JET edge CXS spectrometers is presented that uses a combination of the fringe pattern created with a Fabry–Pérot etalon and a ...

Overview of physics studies on ASDEX Upgrade
(IOP Publishing, 2019-11)
The ASDEX Upgrade (AUG) programme, jointly run with the EUROfusion MST1 task force, continues to significantly enhance the physics base of ITER and DEMO. Here, the full tungsten wall is a key asset for extrapolating to ...

Studies of the pedestal structure and inter-ELM pedestal evolution in JET with the ITER-like wall
(IOP Publishing, 2017-11)
The pedestal structure of type I ELMy H-modes has been analysed for JET with the ITERlike Wall (JET-ILW). The electron pressure pedestal width is independent of ρ* and increases proportionally to √βpol,PED. Additional ...

First measurements of an imaging heavy ion beam probe at the ASDEX Upgrade tokamak
(American Institute of Physics, 2024-01-11)
The imaging heavy ion beam probe (i-HIBP) diagnostic has been successfully commissioned at ASDEX Upgrade. The i-HIBP injects a primary neutral beam into the plasma, where it is ionized, leading to a fan of secondary (charged) ...

ELM-induced cold pulse propagation in ASDEX Upgrade
(IOP Publishing, 2019-05)
In ASDEX Upgrade, the propagation of cold pulses induced by type-I edge localized modes (ELMs) is studied using electron cyclotron emission measurements, in a dataset of plasmas with moderate triangularity. It is found ...
