MoEDAL shares the cavern at Point 8 with LHCb, and its prime goal is to directly search for the magnetic monopole (MM) or

dyon In physics, a dyon is a hypothetical particle in 4-dimensional theories with both electric and magnetic charges. A dyon with a zero electric charge is usually referred to as a magnetic monopole. Many grand unified theories predict the existence of ...

(SMPs) and pseudo-stable massive particles via the Schwinger effect. To detect these particles, the project uses nuclear track detectors (NTDs), which suffer characteristic damage due to highly ionizing particles. As MMs and SMPs are highly ionizing, NTDs are perfectly suited for the purpose of detection. It is an international research collaboration whose spokesperson is the University of Alberta's James Pinfold. It is the seventh experiment at the LHC, was approved and sanctioned by the

A new detector was installed in 2015, but as of 2017 it also did not find any magnetic monopoles, setting new limits on their production cross section.
