Searching for magnetic monopoles trapped in accelerator material at the Large Hadron Collider

Understand

If produced in high energy particle collisions at the LHC, magnetic monopoles could stop in material surrounding the interaction points.

• Obsolete parts of the beam pipe near the CMS interaction region, which were exposed to the products of pp and heavy ion collisions, were analysed using a SQUID-based magnetometer.
• The purpose of this work is to quantify the performance of the magnetometer in the context of a monopole search using a small set of samples of accelerator material ahead of the 2013 shutdown.
