- For a broad range of values of magnetic monopole mass and charge, the abundance of monopoles trapped inside Earth would be expected to be enhanced in the mantle beneath the geomagnetic poles. A search for magnetic monopoles was conducted using the signature of an induced persistent current following the passage of igneous rock samples through a SQUID-based magnetometer. A total of 24.6 kg of rocks from various selected sites, among which 23.4 kg are mantle-derived rocks from the Arctic and Antarctic areas, was analyzed. No monopoles were found, and a 90% confidence level upper limit of 9.8 x 10(-5)/g is set on the monopole density in the search samples.

Studies of triggering and exotic particle searches at ATLAS, and a search for trapped monopoles
- 2013

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The ATLAS detector at the LHC operated through 2011 and 2012 with 7 and 8 TeV centre-of-mass energy of its colliding proton bunches, respectively. One if its main objectives is to search for physics beyond the Standard Model. This thesis presents a study of a data-driven background method designed for long-lived heavy particles searches, where the signatures are allowed by for example R-parity violating Supersymmetry. Several studies of the perfor- mance of ATLAS trigger system have also been carried out. A contribution to a non-ATLAS search for primordial trapped magnetic monopoles was also undertaken. Data-taking and calibration of a SQUID magnetometer used when searching for magnetic monopoles in volcanic polar rocks were carried out.
