Abstract. In 2010 the MoEDAL experiment at the Large Hadron Collider (LHC) was unanimously approved by CERN's Research Board to start data taking in 2015. MoEDAL is a pioneering experiment designed to search for highly ionizing messengers of new physics such as magnetic monopoles or massive (pseudo-)stable charged particles. Its groundbreaking physics program defines a number of scenarios that yield potentially revolutionary insights into foundational questions. MoEDAL's purpose is to meet such farreaching challenges at the frontier of the field. The innovative MoEDAL detector is tuned to the prospect of discovery physics. The largely passive MoEDAL detector, deployed at Point 8 on the LHC ring, has a dual nature. First, it acts like a giant camera, comprised of nuclear track detectors -analyzed offline by ultra fast scanning microscopes -sensitive only to new physics. Second, it is uniquely able to trap the particle harbingers of new physics beyond the Standard Model for further study. MoEDAL's radiation environment is monitored by a state-of-the-art real-time TimePix pixel detector array.

Abstract. MoEDAL is designed to search for monopoles produced in high-energy Large Hadron Collider (LHC) collisions, based on two complementary techniques: nucleartrack detectors for high-ionisation signatures and other highly ionising avatars of new physics, and trapping volumes for direct magnetic charge measurements with a superconducting magnetometer. The MoEDAL test trapping detector array deployed in 2012, consisting of over 600 aluminium samples, was analysed and found to be consistent with zero trapped magnetic charge. Stopping acceptances are obtained from a simulation of monopole propagation in matter for a range of charges and masses, allowing to set modelindependent and model-dependent limits on monopole production cross sections. Multiples of the fundamental Dirac magnetic charge are probed for the first time at the LHC. IntroductionMagnetic monopoles were first postulated by Dirac in 1931, who showed that with their existence, electric charge quantisation could be explained as a natural consequence of angular momentum quantisation [1]. Their introduction would also add symmetry to Maxwell's equations of electromagnetism. 't Hooft and Polyakov, in 1974, independently demonstrated that a Grand Unified Theory (GUT) scheme possesses a monopole solution when a U(1) subgroup of electromagnetism that is embedded into a larger gauge group is spontaneously broken by the Higgs mechanism [2,3]. Monopole solutions have been proposed to arise within the electroweak theory itself [4], which relies on spontaneous gauge symmetry breaking. The Cho-Maison electroweak monopole would have a mass of the order of several TeV [5,6] and is possibly within the range of the Large Hadron Collider (LHC). With the abundance of monopole theories and no definite estimate on its mass, the search for free magnetic charges in nature is compelling.Dirac proposed that the monopoles should carry a magnetic charge g equal to the multiple of a fundamental unit of magnetic charge referred to as the Dirac charge g D : g = n.g D , where g D is equivalent to 68.5 times the charge of an electron. The minimum value of the quantisation number n varies between different theories. According to Dirac, n = 1, 2, 3.., while according to Schwinger, as well as, Cho and Maison, n = 2, 4, 6.. [4,7], and n = 3, 6, 9.. or n = 6, 12, 18.. if one considers the elementary charge to be carried by the down quark. As a result of the high value of the Dirac magnetic charge, a high velocity monopole is expected to suffer energy losses in matter over ≈4700 times higher than a muon [8][9][10]. Thus, in general monopoles in nature will manifest themselves as a
