Quadrupole magnet

Quadrupole Magnet

A quadrupole magnet is an electromagnet with four symmetrically arranged poles that uses the force exerted on a charged-particle beam passing through its magnetic field to focus the beam, converging or diverging its width. While a bending magnet redirects the beam’s path, a quadrupole magnet acts more like a lens, keeping the beam focused and preventing it from spreading. The focusing performance is determined by design parameters such as the field gradient and bore diameter.

Below are the specifications of the quadrupole magnet (5 sets) installed at Chosun University Hospital.
