A precise measurement of the proton flux in primary cosmic rays with rigidity (momentum/charge) from 1 GV to 1.8 TV is presented based on 300 million events. Knowledge of the rigidity dependence of the proton flux is important in understanding the origin, acceleration, and propagation of cosmic rays. We present the de…

Magnetospheric substorms explosively release solar wind energy previously stored in Earth's magnetotail, encompassing the entire magnetosphere and producing spectacular auroral displays. It has been unclear whether a substorm is triggered by a disruption of the electrical current flowing across the near-Earth magnetot…

Knowledge of the precise rigidity dependence of the helium flux is important in understanding the origin, acceleration, and propagation of cosmic rays. A precise measurement of the helium flux in primary cosmic rays with rigidity (momentum/charge) from 1.9 GV to 3 TV based on 50 million events is presented and compare…

A precision measurement by AMS of the antiproton flux and the antiproton-to-proton flux ratio in primary cosmic rays in the absolute rigidity range from 1 to 450 GV is presented based on $3.49\ifmmode\times\else\texttimes\fi{}1{0}^{5}$ antiproton events and $2.42\ifmmode\times\else\texttimes\fi{}1{0}^{9}$ proton event…

Knowledge of the rigidity dependence of the boron to carbon flux ratio (B/C) is important in understanding the propagation of cosmic rays. The precise measurement of the B/C ratio from 1.9 GV to 2.6 TV, based on 2.3 million boron and 8.3 million carbon nuclei collected by AMS during the first 5 years of operation, is…

We report the observation of new properties of primary cosmic rays He, C, and O measured in the rigidity (momentum/charge) range 2 GV to 3 TV with $90\ifmmode\times\else\texttimes\fi{}{10}^{6}$ helium, $8.4\ifmmode\times\else\texttimes\fi{}{10}^{6}$ carbon, and $7.0\ifmmode\times\else\texttimes\fi{}{10}^{6}$ oxygen nu…

The effect of large amplitude chorus on energetic, radiation‐belt electrons is evaluated using a general, relativistic, oblique, test‐particle code. Three specific cases are examined: (A) Low‐amplitude waves interacting at low‐latitudes exhibit the expected, linear scattering which leads to large‐scale diffusive behav…

Companion papers in this series present (1) the role of equatorial E region postsunset ionosphere, (2) the origin of horizontal plasma shear flow in the postsunset equatorial ionosphere (this paper), (3) the Coloured Bubbles experiments results, and (4) computer simulations of artificial initiation of plasma density d…

Abstract We present analytic expressions for ULF wave‐derived radiation belt radial diffusion coefficients, as a function of L and Kp, which can easily be incorporated into global radiation belt transport models. The diffusion coefficients are derived from statistical representations of ULF wave power, electric field…
