Electron Heating by the Cross-shock Electric Potential Electron Heating by the Cross-shock Electric Potential
Electrons can experience super-adiabatic heating at a collisionless shock due to the presence of a cross-shock electric potential. This heating can greatly exceed the temperature rise associated with the conservation of the magnetic moment of the electrons as they move into the stronger magnetic eld downstream of the shock. The criterion for the onset of super-adiabatic heating and the eeects o...
متن کاملComparison of three methods for the estimation of cross-shock electric potential using Cluster data
Cluster four point measurements provide a comprehensive dataset for the separation of temporal and spatial variations, which is crucial for the calculation of the cross shock electrostatic potential using electric field measurements. While Cluster is probably the most suited among present and past spacecraft missions to provide such a separation at the terrestrial bow shock, it is far from idea...
متن کاملDirect measurement of the cross-shock electric potential at low plasma β, quasi-perpendicular bow shocks
We use the Cluster EFW experiment to measure the cross-shock electric field at ten low β, quasi-perpendicular supercritical bow shock crossings on March 31, 2001. The electric field data are Lorentz-tranformed to a Normal Incidence frame (NIF), in which the incoming solar wind velocity is aligned with the shock normal. In a boundary normal coordinate system, the cross-shock (normal) electric fi...
متن کاملDiabetes unmasked by electric shock.
Following an accidental electric shock, a boy with no previous symptoms developed hyperglycaemia, rapidly evolving into diabetes. He was aglycosuric for 24 hours after the shock. Islet cell antibodies were shown shortly after the accident. Although destined to develop diabetes, it seems likely that the electric shock unmasked impaired glucose tolerance. Glucose homoeostasis should be monitored ...
متن کاملStudy on Poloidal and Toroidal Electric Field Generations by Electron Cyclotron Heating in a Helical Plasma
Poloidal and toroidal electric fields generated by electron cyclotron heating are studied in a helical plasma. A linearized Fokker-Planck equation is solved by the adjoint method, assuming a helically symmetric configuration for simplicity. It is found that the poloidal and toroidal electric fields are generated near the bottom of the magnetic ripple, and that the larger radial flux is enhanced...
