AbstractThe fundamental idea of Laser Wakefield Acceleration (LWFA) is reviewed.
An ultrafast intense laser pulse drives coherent wakefields of relativistic
amplitude with the high phase velocity robustly supported by the plasma. The
structures of wakes and sheaths in plasma are contrasted. While the large
amplitude of wakefields involves collective resonant oscillations of the
eigenmode of the en... hiện toàn bộ
Abstract Collisional and turbulent transport processes in toroidal plasmas with
large toroidal flows on the order of the ion thermal velocity are formulated
based on the modern gyrokinetic theory. Governing equations for background and
turbulent electromagnetic fields and gyrocenter distribution functions are
derived from the Lagrangian variational principle with effects of collisions and
external... hiện toàn bộ
AbstractIn this review, we summarize recent advances in the field of dusty
plasmas at strong magnetic fields. Special emphasis is put on situations where
experimental laboratory observations are available. These generally comprise
dusty plasmas with magnetized electrons and ions, but unmagnetized dust. The
fundamental parameters characterizing a magnetized (dusty) plasma are given and
various effe... hiện toàn bộ
The solar wind, a continuous flow of plasma from the sun, not only shapes the
near Earth space environment but also serves as a natural laboratory to study
plasma turbulence in conditions that are not achievable in the lab. Starting
with the Mariners, for more than five decades, multiple space missions have
enabled in-depth studies of solar wind turbulence. Parker Solar Probe (PSP) was
launched to... hiện toàn bộ
AbstractThe non-local transport nature revealed by the research in transient
phenomena of toroidal plasma is reviewed. The following non-local phenomena are
described: core temperature rise in the cold pulse, hysteresis gradient–flux
relation in the modulation ECH experiment, and see-saw phenomena at the internal
transport barrier (ITB) formation. There are two mechanisms for the non-local
transpo... hiện toàn bộ
AbstractIn the following short review we will outline some of the possible
interaction processes of lower solar atmospheric plasma with the embedded
small-scale solar magnetic fields. After introducing the topic, important types
of small-scale solar magnetic field elements are outlined to then focus on their
creation and evolution, and finally end up describing foremost processes these
