Beam-tracing and profile evolution for localised beams in inhomogeneous plasmas
Lewin B. S. Marsh, Felix I. Parra, Valerian H. Hall-Chen +1
We derive the beam tracing and profile evolution for the propagation of any localised beam with arbitrary profile through an inhomogeneous cold plasma. We recover standard Gaussian…

Measurement of zero-frequency fluctuations generated by coupling between Alfven modes in the JET tokamak
Juan Ruiz Ruiz, Jeronimo Garcia, Michael Barnes +13
We report the first experimental detection of a zero-frequency fluctuation that is pumped by an Alfvèn mode in a magnetically confined plasma. Core-localized bidirectional Alfvèn m…

Stable Deuterium-Tritium burning plasmas with improved confinement in the presence of energetic-ion instabilities
Jeronimo Garcia, Yevgen Kazakov, Rui Coelho +18
Providing stable and clean energy sources is a necessity for the increasing demands of humanity. Energy produced by fusion reactions, in particular in tokamaks, is a promising path…
