The Ring Current, Geomagnetic Disturbance, and the Van Allen Radiation Belts
The large decrease in the horizontal component of the earth's field during the main phase of magnetic storms has been ascribed to the formation or enhancement of a geomagnetic ring current. In this paper we discuss the motions of particles trapped in the earth's dipole field and the resulting ring current. These calculations deal only with a steady state, though during storms the state is chang...
متن کاملWave-induced loss of ultra-relativistic electrons in the Van Allen radiation belts
The dipole configuration of the Earth's magnetic field allows for the trapping of highly energetic particles, which form the radiation belts. Although significant advances have been made in understanding the acceleration mechanisms in the radiation belts, the loss processes remain poorly understood. Unique observations on 17 January 2013 provide detailed information throughout the belts on the ...
متن کاملThe Van Allen Probes Engineering Radiation Monitor: Mission Radiation Environment and Effects
The engineering radiation monitor (ERM) measures dose, dose rate, and charging currents on the Van Allen Probes mission to study the dynamics of Earth’s Van Allen radiation belts. Measurements from this monitor show a variation in dose rates with time, a correlation between the dosimeter and charging current data, a map of charging current versus orbit altitude, and a comparison of measured cum...
متن کاملRadiation dosage in flight through the Van Allen belt.
A B O U T ten years ago, when avialion medicine developed a seri,ous interest in the problem of cosmic ray ,hazards in flight at the top of and outside the atmosphere, it became common practice to express cosmic ray intensities in terms of tissue ionization dosages, that is, in roentgens equivalent physical ( rep) . This expedited ~he interpretation of the ~;lata of the physicists inasmuch as e...
متن کاملCollateral Pulmonary Respiration of Van Allen
process was impaired by inflammation.3,9 These observations were confirmed by means of gas analysis by Lindskog and Van Allen.A Collateral respiration was also demonstrated in relation to experimental segmental emphysema produced by valvular bronchial obstruction. Lobar emphysema followed valvular obstruction of lobar bronchi, but no emphysema resulted from this type of obstruction in the prima...
