标题： Search for magnetic monopoles with nuclear track detectors

摘要： 本文描述了在MACRO实验中使用核径迹子探测器CR39对GUT磁单极子的实验搜索。在讨论了工作原理、电荷分辨率和探测器的标定后，描述了搜索磁单极子的实验过程。由于未发现候选事件，给出了MACRO CR39作为"独立探测器"用于不同磁电荷的磁单极子的通量上限限制。 显示英文摘要

摘要： 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.
