Search for magnetic monopoles with nuclear track detectors
M. Giorgini (Bologna University, INFN for the MACRO Collaboration)
TL;DR
This paper reports an experimental search for GUT magnetic monopoles using nuclear track detectors, setting upper flux limits due to no candidates being found.
Contribution
It introduces a novel application of CR39 nuclear track detectors in the MACRO experiment for magnetic monopole detection and provides flux limits for various magnetic charges.
Findings
No magnetic monopole candidates were observed.
Upper flux limits were established for different magnetic charges.
The detector's charge resolution and calibration methods were detailed.
Abstract
This paper describes an experimental search for GUT magnetic monopoles in the MACRO experiment using the nuclear track subdetector CR39. After discussing the working principle, the charge resolution and the calibration of the detector, the experimental procedure for searching for magnetic monopoles is described. Since no candidates were found, the upper flux limits obtained by the MACRO CR39 used as a "stand alone detector" for magnetic monopoles of different magnetic charges are presented.
