“…The turbulence in the plasma core was studied also using correlation reflectometry [17]. A combination of these diagnostics provided a unique opportunity to study core turbulences and GAM-associated oscillations of plasma potential in a wide radial interval and to investigate the temperature dependence of GAM frequency, complementing results achieved on CASTOR [18]. The edge turbulence analysis included comparison of probability density function (PDF) in the scrape-off layer (SOL) of T-10 and TCABR, showing similar features and demonstrating strong non-Gaussian PDF in the SOL while in the vicinity of the last closed flux surface (LCFS) the PDF was much closer to the Gaussian.…”

Joint experiments (JEs) on small tokamaks have been regularly performed between 2005 and 2015 under the framework of the International Atomic Energy Agency (IAEA) coordinated research projects (CRPs). This paper describes the background and the rationale for these experiments, how they were organized and executed, main areas of research covered during these experiments, main results, contributions to mainstream fusion research, and discusses lessons learned and outcomes from these activities. We underline several of the most important scientific outputs and also specific outputs in the education of young scientists and scientists from developing countries and their importance.

The non-linear cosmic web environment of dark matter haloes plays a major role in shaping their growth and evolution, and potentially also affects the galaxies that reside in them. We develop an analytical (halo model) formalism to describe the tidal field of anisotropic halo-centric density distributions, as characterised by the halo-centric tidal tensor 〈 Tij 〉( < R) spherically averaged on scale R ∼ 4Rvir for haloes of virial radius Rvir. We focus on axisymmetric anisotropies, which allows us to explore simple and intuitive toy models of (sub)halo configurations that exemplify some of the most interesting anisotropies in the cosmic web. We build our models around the spherical Navarro-Frenk-White (NFW) profile after describing it as a Gaussian mixture, which leads to almost fully analytical expressions for the ‘tidal anisotropy’ scalar α( < 4Rvir) extracted from the tidal tensor. Our axisymmetric examples include (i) a spherical halo at the axis of a cylindrical filament, (ii) an off-centred satellite in a spherical host halo and (iii) an axisymmetric halo. Using these, we demonstrate several interesting results. For example, the tidal tensor at the axis of a pure cylindrical filament gives α(fil)( < R) = 1/2 exactly, for any R. Also, α( < 4Rvir, sat) for a satellite of radius Rvir, sat as a function of its host-centric distance is a sensitive probe of dynamical mass loss of the satellite in its host environment. Finally, we discuss a number of potentially interesting extensions and applications of our formalism that can deepen our understanding of the multi-scale phenomenology of the cosmic web.
