Observation of the rare B-s(0)->mu(+)mu(-) decay from the combined analysis of CMS and LHCb data

Horst Vogel, Christoph Frei, Peter Clarke, Jean Wicht, Alessandro Mapelli, Aurelio Bay, Minh Tâm Tran, Andrea Rizzi, Marc-Olivier Bettler, Cédric Potterat, Matthias Finger, Tatsuya Nakada, Guido Haefeli, Niko Neufeld, Olivier Schneider, Pierre Jaton, Hans Dijkstra, Julien Rouvinet, Charles Dietz, João Miguel das Neves Duarte, Frédéric Guillaume Dupertuis, Frédéric Teubert, Gerhard Raven, Quentin Python, Bastien Luca Muster, Joo Yeon Kim, Alexis Kalogeropoulos, Chitsanu Khurewathanakul, Frédéric Blanc, Matthew Needham, Lesya Shchutska, Liang Sun, Alexandre Aubin, Yixing Chen, Tian Cheng, Ioannis Papadopoulos, Wei Sun, Barinjaka Rakotomiaramanana, Xiaoxue Han, Qian Wang, , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,

Overview of the FTU results

Basil Duval, Olivier Sauter, Holger Reimerdes, Jonathan Rossel, Alexander Karpushov, Duccio Testa, Lucia Isabel Federspiel, Dávid Wágner, Gabriele Grosso, Doohyun Kim, Cristian Galperti, Donghyun Kim

Since the 2012 IAEA-FEC Conference, FTU operations have been largely devoted to runaway electrons generation and control, to the exploitation of the 140 GHz electron cyclotron (EC) system and to liquid metal limiter elements. Experiments on runaway electro ...

Selected highlights of ECH/ECCD physics studies in the TCV tokamak

Basil Duval, Timothy Goodman, Olivier Sauter, Stefano Coda, Federico Alberto Alfredo Felici, Doohyun Kim, Joan Decker, Donghyun Kim

The Tokamak a Configuration Variable, TCV, has used Electron Cyclotron Heating and Current Drive as its only auxiliary heating system for nearly two decades. In addition to basic plasma heating and current profiling, ECH and ECCD under either feedforward o ...

Effects of central electron cyclotron power on plasma rotation and on triggerless onset of NTMs in the TCV tokamak

Basil Duval, Olivier Sauter, Holger Reimerdes, Jonathan Rossel, Alexander Karpushov, Duccio Testa, Lucia Isabel Federspiel, Dávid Wágner, Doohyun Kim, Donghyun Kim

Experiments on the TCV tokamak show that high power central electron cyclotron heating (ECH) and current drive (ECCD) produce significant direct modification of the plasma rotation profile, as well as the effect on the equilibrium current density. These ef ...

Real-Time Control of Sawteeth and NTMs in TCV and ITER

Doohyun Kim

The main goal of this thesis is to demonstrate the capability of magneto-hydrodynamic (MHD) instability control, particularly sawteeth and neoclassical tearing modes (NTMs), in order to achieve high performance operation. Experiments and simulations have b ...

On the non-stiffness of edge transport in L-mode tokamak plasmas

Stephan Brunner, Roland Behn, Basil Duval, Timothy Goodman, Olivier Sauter, Stefano Coda, Alexander Karpushov, Yann Camenen, Lucia Isabel Federspiel, Doohyun Kim, Gabriele Merlo, Antoine Pierre Emmanuel Alexis Merle, Donghyun Kim

Transport analyses using first-principle turbulence codes and 11/2-D transport codes usually study radial transport properties between the tokamak plasma magnetic axis and a normalized minor radius around 0.8. In this region, heat transport shows significa ...

Real-time sawtooth control and NTM preemption in ITER

Timothy Goodman, Olivier Sauter, Doohyun Kim, Donghyun Kim

Real-time control of multiple plasma actuators is a requirement in advanced tokamaks; for example, for burn control, plasma current profile control and MHD stabilization electron cyclotron (EC) wave absorption is ideally suited especially for the latter. O ...
