Impact of the plasma operation on the technical requirements in EU-DEMO

Olivier Sauter, Minh Quang Tran, Emiliano Fable, Simon Van Mulders, Hartmut Zohm

The plasma design point during stationary phase operation of EU-DEMO has been described extensively in the past, and the assumptions employed for its definition have been supported by various investigations. However, a stationary snapshot is by far not suf ...

L-mode plasmas analyses and current ramp-up predictions for a JT-60SA hybrid scenario

Timothy Goodman, Javier García Hernández, Matteo Vallar

In this work, L-mode analyses are performed in order to assess a modeling framework for the prediction of electron cyclotron resonant heating (ECRH) -assisted current ramp-up phases for JT-60SA tokamak hybrid scenario #4-2. We compare two turbulence transp ...

Shaping effects on scrape-off layer plasma turbulence: A rigorous validation of three-dimensional simulations against TCV measurements

Paolo Ricci, Fabio Riva, Cedric Kar-Wai Tsui

The effect of plasma shaping on scrape-off layer (SOL) plasma turbulence is investigated through a rigorous validation exercise. Two- and three-dimensional simulations of the SOL plasma dynamics in three TCV limited discharges are carried out with the GBS ...

Update of ion-optical system of neutral beam of Tokamak a Configuration Variable

Alexander Karpushov

An injector of fast deuterium atoms for plasma heating was designed and installed at the Tokamak a Configuration Variable (TCV). The neutral beam can deliver 1 MW power to the plasma in 2 s pulses. An ion beam of the injector is formed by a triode multisli ...

Residual stresses of friction melt bonded aluminum/steel joints determined by neutron diffraction

Jean-Marie Drezet

Near interfacial residual stresses are investigated in a joint composed of aluminum alloy and dual phase steel. A small step neutron diffraction scan was initially performed to determine the weld interface position along the measured transverse cross secti ...

Folded-Tube Soft Pneumatic Actuators for Bending

Wyatt Marshall Felt

This article presents a model and experimental results for a new class of bending soft pneumatic actuators (SPAs) made from a single section of thin-walled flexible tubing. The actuator is formed by creasing the tubing into fin-like rectangular folds and i ...

Basic creep of cement paste at early age - the role of cement hydration

Karen Scrivener, Pietro Lura

In this work, the uniaxial creep in compression during the first days of hydration is studied experimentally on cement pastes with w/c of 0.50. to order to assess the effect of the evolving microstructure on creep, the so-called equivalent systems are empl ...

Influence of the optical measurement technique and evaluation approach on the determination of local weld geometry parameters for different weld types

Alain Nussbaumer, Martin Antonio René Garcia

The joining by welding processes of components is usually related to the creation of additional notches and geometrical peculiarities. Multiple investigations have shown that a clear correlation between the local weld geometry and the fatigue life of welde ...
