A quadrupole magnet is a type of magnet used primarily in particle accelerators and beamlines for focusing charged particle beams. It generates a magnetic field with a specific spatial variation that can focus or defocus charged particles in two transverse directions, allowing for tighter control of the beam's shape and trajectory.
