... mm, an internal diameter of 25 mm and an integrated gradient of 3.3 Tm/m. It is made with soft iron poles with adjustable pole strength using a principle conceptually similar to that used for the LINAC4 quadrupoles [5]. The overall design concept is shown in Fig. 7. In our case the magnet was therma ...

Assuming that these objects differ from (similarly young) classical radio pulsars only by the presence of the nearby companion, this would give evidence that the field of neutron stars is organized on a relatively large scale, so the ...

Aurora



An aurora is a natural light display in the sky, predominantly seen in the high latitude (Arctic and Antarctic) regions. Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere), where their energy is lost. The resulting ionization and excitation of atmospheric constituents emits light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes. Different aspects of an aurora are elaborated in various sections below.
