متن کاملInjection and extraction magnets: kicker magnets
Each stage of an accelerator system has a limited dynamic range and therefore a chain of stages is required to reach high energy. A combination of septa and kicker magnets is frequently used to inject and extract beam from each stage. The kicker magnets typically produce rectangular field pulses with fast riseand/or fall-times, however, the field strength is relatively low. To compensate for th...
متن کاملWaved albatrosses can navigate with strong magnets attached to their head.
The foraging excursions of waved albatrosses Phoebastria irrorata during incubation are ideally suited for navigational studies because they navigate between their Galápagos breeding site and one specific foraging site in the upwelling zone of Peru along highly predictable, straight-line routes. We used satellite telemetry to follow free-flying albatrosses after manipulating magnetic orientatio...
متن کاملA Quasi-Static Electromagnetic Analysis for Experiments with Strong Permanent Magnets
An electromagnetic analysis is presented for experiments with strong permanent disc magnets. The analysis is based on the well known experiment that demonstrates the effect of circulating eddy currents by dropping a strong magnet through a vertically placed metal cylinder and observing how the magnet is slowly falling through the cylinder with a constant velocity. This experiment is quite spect...
متن کاملSuperconducting Materials for Magnets
Superconducting materials for magnets will be discussed from three viewpoints: firstly the basic physical properties of the materials themselves, secondly the constraints and preferences imposed by the requirements of magnet building and finally, the manufacture of magnet conductors as a commercial product.
