A specialized electromagnetic component featuring four poles, arranged such that alternating poles have opposite magnetic polarity. This configuration generates a magnetic field that increases linearly with the distance from the center. Unlike dipole magnets, which produce a uniform magnetic field, this particular arrangement focuses beams of charged particles, bringing them closer to the axis of the system. An example is its use in particle accelerators where it maintains beam coherence.
The significance of these elements lies in their ability to manipulate the trajectory of charged particle beams. Without these devices, beams would diverge and become unusable in many scientific and industrial applications. They are fundamental to research in high-energy physics, enabling discoveries about the fundamental building blocks of matter. Their development represents a crucial advancement in beam handling technology, originating from early experiments with particle beams and magnetic fields.
