Physics of beam-driven ion cyclotron emission in the large plasma device

Nuclear Fusion
Ion cyclotron emission (ICE) is widely observed from spatially localised minority energetic ion populations in toroidal magnetically confined fusion (MCF) plasmas, both tokamaks and stellarators.

Simulations of ion cyclotron emission from highly energetic fusion-born protons in aneutronic deuterium-helium-3 plasmas

Nuclear Fusion
Studies of future aneutronic fusion plasmas, such as those comprising deuterium and helium-3 (D– $^3\mathrm{He}$    $\rightarrow \mathrm{^4He}+p$ ), may not be able to exploit neutron-based diagnostics for direct measurement of fusion reactivity.

Observations of core ion cyclotron emission on ASDEX Upgrade tokamak [PDF]

, 2018
The B-dot probe diagnostic suite on the ASDEX Upgrade tokamak has recently been upgraded with a new 125 MHz, 14 bit resolution digitizer to study ion cyclotron emission (ICE).

Observation of quasi-periodic solar radio bursts associated with propagating fast-mode waves [PDF]

, 2016
Aims. Radio emission observations from the Learmonth and Bruny Island radio spectrographs are analysed to determine the nature of a train of discrete, periodic radio “sparks” (finite-bandwidth, short-duration isolated radio features) which precede a type

Particle Energization in an Expanding Magnetized Relativistic Plasma

, 2003
Using a 2-1/2-dimensional particle-in-cell (PIC) code to simulate the relativistic expansion of a magnetized collisionless plasma into a vacuum, we report a new mechanism in which the magnetic energy is efficiently converted into the directed kinetic ...

Measured reduction in Alfv\'en wave energy propagating through longitudinal gradients scaled to match solar coronal holes [PDF]

, 2019
We have explored the effectiveness of a longitudinal gradient in Alfv\'en speed in reducing the energy of propagating Alfv\'en waves under conditions scaled to match solar coronal holes.

Heavy-Fermion Instability in Double-Degenerate Plasmas

, 2012
In this work we study the propagations of normal frequency modes for quantum hydrodynamic (QHD) waves in the linear limit and introduce a new kind of instability in a double-degenerate plasma.
