Long-term pan evaporation observations as a resource to understand the water cycle trend: case studies from Australia

Acceleration of the global water cycle over recent decades remains uncertain because of the high inter-annual variability of its components. Observations of pan evaporation (E-pan), a proxy of potential evapotranspiration (ETp), may help to identify trends ...

Observations on turbulence and beam-ion driven modes in TEXTOR

Stefano Coda, Mattia Albergante, Cornelis Adrianus de Meijere

At a sufficiently weak toroidal magnetic field, neutral beam injection heated, limited plasmas in the TEXTOR tokamak exhibit bursts of beam-ion driven 'fishbone' and Alfven modes, which are characterized for the first time using the multi-antenna reflectom ...

Rotation studies in electron Internal Transport Barriers on TCV

Olivier Sauter, Basil Duval, Stefano Coda, Alexander Karpushov, Yanis Andrebe, Lucia Isabel Federspiel

This paper reports simultaneous measurements of intrinsic toroidal and poloidal plasma rotation during the evolution of electron Internal Transport Barriers (eITBs) on TCV. A CXRS diagnostic-beam system provides ion parameter profiles for stationary pre-ba ...

Indirect measurement of poloidal rotation using inboard–outboard asymmetry of toroidal rotation and comparison with neoclassical predictions

Olivier Sauter, Basil Duval, Alexander Karpushov, Yanis Andrebe, Yann Camenen, Alessandro Bortolon, Lucia Isabel Federspiel

An alternative experimental spectroscopic measurement of poloidal plasma rotation in toroidally confined plasmas is proven effective in the TCV tokamak. Charge exchange recombination measurements of the toroidal rotation profile over the full mid-plane pla ...

Invited Review Article: Technology for Attosecond Science

Christopher Alexander Arrell

We describe a complete technological system at Imperial College London for Attosecond Science studies. The system comprises a few-cycle, carrier envelope phase stabilized laser source which delivers sub 4 fs pulses to a vibration-isolated attosecond vacuum ...

A unified approach to orbital, solar, and lunar forcing based on the Earth's latitudinal insolation/temperature gradient

Basil Andrew Stansfield Davis

Widespread empirical evidence suggests that extraterrestrial forcing influences the Earth's climate, but how this could occur remains unclear. Here we describe a new approach to this problem that unifies orbital, solar and lunar forcing based on their comm ...

Predictions on heat transport and plasma rotation from global gyrokinetic simulations

Laurent Villard, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Paolo Angelino

Flux-driven global gyrokinetic codes are now mature enough to make predictions in terms of turbulence and transport in tokamak plasmas. Some of the recent breakthroughs of three such codes, namely GYSELA, ORB5 and XGC1, are reported and compared wherever a ...

Peak neoclassical toroidal viscosity at low toroidal rotation in the DIII-D tokamak

Holger Reimerdes

Observation of a theoretically predicted peak in the neoclassical toroidal viscous (NTV) force as a function of toroidal plasma rotation rate is reported. The NTV was generated by applying n = 3 magnetic fields from internal (I-)coils to low plasmas produc ...
