Abstract: A borehole muon detector for detecting and characterizing a geographic region of interest is provided, the borehole muon detector comprising a housing and sensor, which is housed in the housing, the sensor including: a plurality of photodetector elements; at least one printed circuit board in electrical communication with the plurality of photodetectors and including an integrated electronic circuit for tracking time; a first helical bundle of scintillator fibers; an oppositely wound helical bundle of scintillator fibers, the oppositely wound helical bundle, the first helical bundle and the opposite helical bundle defining an outer cylinder, which includes a first end and a second end and a bore therebetween, each scintillator fiber of each bundle directly optically connected to a photodetector element at least at one end and indirectly optically connected to the photodetector element at no more than one end; and a plurality of scintillator bars, each comprising a first end, a second end and an optical fiber extending from the first end to the second end, the plurality of scintillator bars vertically disposed in the bore of the outer cylinder, each optical fiber of the scintillator bar optically directly connected to a photodetector element at least at one end and indirectly optically connected to the photodetector at no more than one end.
