Abstract: A borehole muon detector for muon radiography or geotomography is provided, the borehole muon detector including a substantially cylindrical housing, which defines a bore, a pair of end caps, each end cap sealing an end of the cylindrical housing and a plurality of sealed drift tubes which are longitudinally disposed in the bore of the housing to form a bundle of drift tubes, wherein each sealed drift tube comprises: a centrally located anode wire disposed on a longitudinal axis; an inner surface which is coated with a cathode coating, the cathode coating divided into a first cathode pad and a second cathode pad by a Vernier pattern; and a timer in electrical communication with the anode wire for measuring a drift time. A system and a method are also provided.

Abstract: A longitudinally extending detector drill rod is connectable at each of its longitudinal ends to another drill rod in a drill string and is deployable, as part of the drill string, to a location below a surface of the earth for detecting cosmic ray muons that penetrate the surface of the earth. The detector drill rod comprises: a drill rod bore-defining surface that defines a longitudinally extending drill rod bore; and one or more muon sensors located in the drill rod bore, the one or more muon sensors responsive to muons interacting therewith.

Abstract: A gas electron multiplier (GEM), used to track cosmic ray muons, can have readout electrodes oriented in a helical pattern so that it can fit inside a narrow aperture borehole. The helical orientation of the readout electrodes provides for high spatial resolution and yet is cost effective to manufacture. The GEM can have an insulation layer, a plurality of conduction layers and an inner layer comprising a plurality of helical conductive stripes extending between two ends of the GEM.

Abstract: A borehole muon detector comprises a sensor housed in a 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; and an oppositely wound helical bundle of scintillator fibers. Each scintillator fiber of each bundle is optically connected to a photodetector. The sensor comprises a plurality of scintillator bars, each comprising an optical fiber extending from a first end to a second end, and vertically disposed in the bore defined by the helical bundles of fibers. Each optical fiber of each scintillator bar is optically connected to a photodetector element.
