The cross-section of tokamak plasmas is usually non-circular; the plasma column tends to be vertically elongated and "D"-shaped. The shaping parameter that characterizes the "D"-ness is called triangularity. In recent years, the exotic negative triangularity (NT) shape has attracted renewed interest in the fusion community. NT corresponds to a cross-section resembling a flipped "D" (Figure 1). Figure 1: Sketch of tokamak plasma cross-sections with (a)...

Despite its modest size, Enceladus exerts a colossal electromagnetic influence on Saturn’s environment. An international study led by researchers from the Laboratory of Plasma Physics (LPP) reveals that this moon acts as a giant planetary-scale Alfvén wave generator, extending its wake over more than 500,000 km. Distribution spatiale des cas des évènements présentant une perturvation Alfvénique connectée à l'orbite d'Encelade. A Record Footprint on a...

In their two-part tutorial review published in Plasma Sources Science and Technology, Svetlana Starikovskaia, Victor Lafaurie, Jean-Baptiste Perrin-Terrin (EM2C), and Christophe Laux (EM2C) present a comprehensive overview of plasma-assisted combustion (PAC). The review is explicitly structured to guide readers from fundamental combustion and plasma physics to the mechanisms and practical applications relevant to modern energy and propulsion systems...
