For many years, machine learning tools have proved to be very powerful disruption predictors in tokamaks. On the other hand, the vast majority of the techniques deployed assume that the input data is independent and is sampled from exactly the same probabi ...

Patrick Blanchard, Basil Duval, Ambrogio Fasoli, Richard Pitts, Olivier Sauter, Henri Weisen, Marco Wischmeier, Jan Horacek, Yann Camenen, Jonathan Graves, Francesca Maria Poli, Duccio Testa, Emiliano Fable, Mikhail Maslov, Javier García Hernández, Federico Alberto Alfredo Felici, Daniele Brunetti, Antoine Pierre Emmanuel Alexis Merle, Federico Nespoli, Anna Teplukhina, Leonardo Pigatto, Hamish William Patten, Alberto Mariani, Nicola Vianello, Antonio José Pereira de Figueiredo, Samuel Lanthaler, Cristian Sommariva, Davide Galassi, Alessandro Pau, Yao Zhou, Otto Asunta, Kenji Tanaka, Haomin Sun, Michele Marin, Yiming Li, Gergely Papp, Bernhard Sieglin

Deuterium pellets are injected into an initially pure hydrogen H-mode plasma in order to control the hydrogen: deuterium (H:D) isotope mixture. The pellets are deposited in the outer 20% of the minor radius, similar to that expected in ITER, creating trans ...

Experimental Observation of Plasma Wakefield Growth Driven by the Seeded Self-Modulation of a Proton Bunch

Sun Hee Kim, Gennady Plyushchev, Ishkhan Gorgisyan, Sijie Liu, Michele Marin, Yiming Li, Shuai Liu

We measure the effects of transverse wakefields driven by a relativistic proton bunch in plasma with densities of 2.1 x 10(14) and 7.7 x 10(14) electrons/cm(3). We show that these wakefields periodically defocus the proton bunch itself, consistently with t ...
