Disruption-caused railway timetable rescheduling problem and its solution

In the framework of this master thesis an adaptive large neighborhood search meta-heuristic is implemented to solve the disruption caused railway timetable rescheduling problem. The multi-objective optimisation tries to minimize the travel time of passenge ...

RAMI evaluation of the beam source for the DEMO neutral beam injectors

Minh Quang Tran

DEMO is a first-of-a-kind DEMOnstration fusion power plant [1,2] and is intended to follow the ITER experimental reactor. The main goal of DEMO will be to demonstrate the possibility to produce electric energy for the grid from the fusion reaction early in ...

A versatile and membrane-less electrochemical reactor for the electrolysis of water and brine

Demetri Psaltis, Christophe Moser, Pooria Hadikhani, Enrico Chinello

Renewables challenge the management of energy supply and demand due to their intermittency. A promising solution is the direct conversion of the excess electrical energy into valuable chemicals in electrochemical reactors that are inexpensive, scalable, an ...

L-mode-edge negative triangularity tokamak reactor

Olivier Sauter, Laurent Villard, Antoine Pierre Emmanuel Alexis Merle

The negative triangularity tokamak (NTT) is a unique reactor concept based on 'power-handling-first' philosophy with the heat exhaust problem as the leading concern. The present paper exposes a reactor concept using L-mode edge based on NTT configuration, ...

H-mode grade confinement in L-mode edge plasmas at negative triangularity on DIII-D

Olivier Sauter, Alessandro Marinoni

Plasmas with a negative triangularity shape have been created on the DIII-D tokamak that, despite maintaining standard L-mode edge radial profiles, reach volume averaged pressure levels typical of H-mode scenarios. Within the auxiliary power available for ...

Effects of collisionality and T e /T i on fluctuations in positive and negative δ tokamak plasmas

Olivier Sauter, Ambrogio Fasoli, Stefano Coda, Stephan Brunner, Laurie Porte, Gabriele Merlo, Matteo Fontana, Ajay Chandrarajan Jayalekshmi

The effects of negative triangularity () on confinement and fluctuations in plasmas covering a large range of parameters were investigated on the tokamak à configuration variable (TCV). The conditions explored in this paper include discharges where neutral ...
