Описание: From the early examples of what was to be called MRI, extending the te- nique to higher fields than those of less than 0. 1 T used in the first large-volume instruments was a goal, but the way there was unclear. The practical success of large superconducting magnets was a surprise, and the astonishment continued as they developed fields from 0. 3 T to 0. 6 T to 1. 5 T, and even more, up to the now common 3T systems, and a few 4T machines, and now to about 100 times the fields used in the first medium- and large-bore devices. In the early machines, low radiofrequencies of 4 MHz or so meant that RF coil designs were simple (even inexperienced undergraduates could design and build such circuits with little knowledge of more than DC electrical circuits), and the forces on gradient coils were small. The effects of magnetic susceptibility in- mogeneity in and around the object being imaged were negligible, and RF penet- tion depths were not a problem for human-scale samples. Everything began to change as higher fields and higher frequencies came into use, and the earlier idyllic simplicities began to seem quaint. The trend continued, however, driven by the increased signal-to-noise ratios and the resultant higher resolutions and speed available, and sophisticated engineering became more and more essential, not only for magnets but for gradient systems and radiofrequency transmitters and receivers, but also for better software for modeling and correcting distortions.

Описание: Indeed, we find trapped radiation elsewhere in the universe: Jupiter`s radiation belts, particle trapping in sunspot magnetic fields, cosmic rays confined in interstellar fields and, possibly, ultra-high-energy particles trapped in the magnetic fields of rotating neutron stars.

Описание: This book surveys methods used at the Antiproton Decelerator at CERN to identify and extrapolate charged particle tracks and estimate the originating annihilation location, in its successful effort to achieve stable, long-term storage of atomic antimatter.
Описание: This thesis describes the essential features of Moon-plasma interactions with a particular emphasis on the Earth`s magnetotail plasma regime from both observational and theoretical standpoints.

Описание: Many geological features of the Earth`s lithosphere create variations in the Earth`s magnetic field that can be detected by satellites. The resulting magnetic anomaly maps can provide insights into the tectonic features and broad structures of the lithosphere. This 1998 book documents the acquisition, reduction and analysis of satellite magnetic field data.

Описание: This thesis focuses on the very high Mach number shock wave that is located sunward of Saturn's strong magnetic field in the continuous high-speed flow of charged particles from the Sun (the solar wind). The author exploits the fact that the Cassini spacecraft is the only orbiter in a unique parameter regime, far different from the more familiar near-Earth space, to provide in-situ insights into the unreachable exotic regime of supernova remnants. This thesis bridges the gap between shock physics in the Solar System and the physics of ultra-high Mach number shocks around the remnants of supernova explosions, since to date research into the latter has been restricted to theory, remote observations, and simulations.
