Significant Suppression of High Electric Field Regions in XLPE via Voltage Stabilisers

High Voltage
Dielectric degradation typically originates from local defects. The resulting electric field concentration accelerates defect growth. Suppressing field distortion arising from such local weaknesses has long been a major challenge in electrical insulation.

Chromospheric evaporation as the driver of helium enrichment in active region solar wind: A case study

Astronomy & Astrophysics
Context. The physical mechanisms of helium abundance (AHe) depletion in the corona and solar wind are closely linked to coronal heating, solar wind origin, and acceleration processes. The relationships between the AHe in the solar wind and the properties

Solar wind origin of terrestrial water

, 2011
The origin of the Earth water reserves during the evolution of the planet is one of the big miracles in geophysics. Common explanations are storage of water in the Earth mantle at a time when the crust had not yet formed and depositing of water by comets

The Magnetopause Boundary [PDF]

In this activity students explore in a quantitative way, how the distance to the bowshock balance point depends on the solar wind pressure acting on the Earth's magnetic field.

Anthrone/XLPE: an adaptive charge capture intelligent insulation material for advanced electric power transmission

Communications Engineering
The degradation of electrical insulation is mainly attributed to local defects. Although incorporating organic small molecules into dielectric polymers promotes the insulation strength, accurate suppression of defect development is a long-term and ...

Cross Helicity and the Helium Abundance as an In Situ Metric of Solar Wind Acceleration

The Astrophysical Journal Letters
The two-state solar wind paradigm is based on observations showing that slow and fast solar wind have distinct properties like helium abundances, kinetic signatures, elemental composition, and charge-state ratios. Nominally, the fast wind originates from

The connection of the Ions and electrons in the Earth’s central plasma sheet to the solar wind

Frontiers in Astronomy and Space Sciences
The simple problems of the solar wind number density driving the plasma sheet number density and the solar wind speed driving the plasma sheet temperature are examined.

Solar-wind control of the extent of planetary ionospheres [PDF]

In our solar system there are at least four magnetic planets: Earth, Jupiter, Mercury, and Mars; while at least one planet, Venus, appears to be essentially nonmagnetic. The ionospheres of the magnetic planets are imbedded in their magnetosphere and thus
