epl draft A note on the collisionless high-β space-plasma mirror mode
The linear threshold condition of the mirror mode including weak drift and finite Larmor radius effects is analysed and shown that it can be given to arbitrary precision in closed analytical form. From the dispersion relation two different modes can be identified, one the positive energy mirror mode, the other a negative energy mode which grows below the positive energy mirror mode threshold an...
متن کاملA universal mirror wave-mode threshold condition for non-thermal space plasma environments
Magnetic fluctuations are recognized in a large variety of space plasmas by increasingly high resolution, in situ observations as mirror wave mode structures. A typical requirement for the excitation of mirror modes is a dominant perpendicular pressure in a high-beta plasma environment. Contrary, we demonstrate from a realistic kinetic analysis how details of the velocity space distributions ar...
متن کاملOn the linear mirror mode threshold in high-β space plasma
The linear threshold condition of the mirror mode including weak drift and finite Larmor radius effects is analysed and shown that it can be given to arbitrary precision in closed analytical form. Combined with observations of mirror modes in the magnetosheath it is shown that only magnetic ‘dips’ are produced by the mirror instability. A semi-experimental threshold condition is derived. The oc...
متن کاملTemperature Anisotropy in a Shocked Plasma: Mirror-mode Instabilities in the Heliosheath
We show that temperature anisotropies induced at a shock can account for interplanetary and planetary bow shock observations. Shocked plasma with enhanced plasma b is preferentially unstable to the mirror-mode instability downstream of a quasi-perpendicular shock and to the fire-hose instability downstream of a quasiparallel shock, consistent with magnetic fluctuations observed downstream of a ...
متن کاملSuperconducting analogue electronics for research and industry
This paper gives a brief review of superconducting electronics in research and industry. Examples will show how science benefits from the development and how superconducting devices have found their way into industry and to some commercial products. Impact in terms of enabling new research in other fields (e.g. radio astronomy, medicine), in industry (certification, safety, metrology, etc) and ...
