The sensor unit is an electron electrostatic, axially symmetrical, toroidal analyzer. ... The energy range for both types of charged particles must stepped according to the logarithmic scale. ...

The efficiency of interaction of radiation with a particle and hence its optical properties depend on the particle chemical composition, size, shape, structure, etc. ... Particle size expressed in units of the wavelength of incident radiation, together with chemical composition, most strongly affects the optical properties of a scatterer. ... There are many methods to solve the light-scattering problem for a homogeneous spheroid (our survey of the light-scattering methods see here ). ...

... Observations of precipitating (Jp) and trapped (Jt) energetic (> 30 keV) particle fluxes at the ionospheric altitudes within the auroral oval region has revealed the existence of a sharp boundary separating the poleward zone of isotropic precipitation (Jp = Jt) from the equatorward zone of weak loss cone filling (Jp << Jt) at all local times (Sergeev and Malkov, 1988). ... boundaries for higher energy particles are located at lower latitudes than boundaries for lower energy particles . ...

The main objective of measurements of charged particles and plasma flux characteristics in the INTERBALL project is to study the spatial structure of the terrestrial magnetosphere as a global system in various scales and for varying external conditions. ... The SPS spectrometer is designed for estimating the ion energy and angular distributions and for measurements of the electron energy distributions. ...

Orbital intersection . ... Structure of Taurid stream . ... Meteoroid swarm and Taurid fireballs . ... The following four diagrams schematically show four different Taurid orbits and the orbits of Earth and Jupiter. ... The Taurid stream contains particles (small, solid grains) at different stages of their precession cycles. ... The study of when a meteor stream can produce a meteor shower is the study of when precession brings orbits to intersection with Earth, or e.g. with Mars . ...

. Dark matter forms the foundation for all cosmic structure, and its annihilation, decay, or other particle interactions have the potential to affect early structure formation by injecting energy into local gas. I will discuss the status of the quest to identify dark matter, major unsolved problems relevant to the abundance and structure of dark matter halos, and how dark matter annihilation energy can affect the binding of gas within the earliest cosmic structures.

... Structure Current Limit Violation on Day 2003/036 . ... HST . ... On DOY 2003/036 at approximately 12:25 GMT (7:25 am local), the structure current flagged out of limits high between 1.4 to 1.6 amps. ... Preliminary analysis indicated that the flagging of the structure current appears to coincide with the opening of the -E trim relay in SA section 3 during trickle charge. ... The anomaly repeated in seven orbits, then stopped suddenly and the structure current returned to its normal behavior. ...
