“…As Figure 13 suggests, in the range from 3200 to about 6000 hg/cm 2 the MACRO data are systematically in excess of our predicted muon intensity by about (8)(9)(10) %, what is beyond the total systematic error estimated in Ref. [44].…”

“…There is a need to piece together all these data in order to extract some physical inferences thereof. Also, it would be useful to correlate the underground and underwater data with the results of the mentioned direct measurements of the sea-level muon spectrum [7][8][9][10][11][12][13][14][15][16][17] as well as with the data deduced by indirect routes [33,36,37,44,[60][61][62][63][64][65][66].…”

Atmospheric muon flux at sea level, underground, and underwater

The vertical sea-level muon spectrum at energies above 1 GeV and the muon intensities at depths up to 18 km w.e. in different rocks and in water are calculated. The results are particularly collated with a great body of the ground-level, underground, and underwater muon data. In the hadron-cascade calculations, we take into account the logarithmic growth with energy of inelastic cross sections and pion, kaon, and nucleon generation in pion-nucleus collisions. For evaluating the prompt muon contribution to the muon flux, we apply the two phenomenological approaches to the charm production problem: the recombination quark-parton model and the quark-gluon string model. We give simple fitting formulas describing our numerical results. To solve the muon transport equation at large depths of a homogeneous medium, we use a semianalytical method, which allows the inclusion of an arbitrary (decreasing) muon spectrum at the medium boundary and real energy dependence of muon energy losses. Our analysis shows that at the depths up to 6-7 km w.e., essentially all underground data on the muon flux correlate with each other and with the predicted one for conventional (π, K)-muons, to within 10 %. However, the high-energy sea-level muon data as well as the data at high depths are contradictory and cannot be quantitatively described by a single nuclear-cascade model.

This article reports on the first application of muon tomography (a novel method for imaging density contrasts underground using cosmic rays) for imaging dense uranium deposits within the Athabasca Basin in Canada. We present a qualitative assessment of the radiographic imaging and 3‐D density inversion of a uranium deposit using muon tomography. The muon tomography survey summarized in this article was performed at the McArthur River mine. We demonstrate the validity of muon tomographic imaging with data acquired at a depth of about 600 m underground. The statistical significance of the uranium deposit signature in the muon data was larger than 5 standard deviations, and the corresponding 3‐D density inversion compared well with drill assay data from the deposit.

The epectra of coamic piom and nucleone at an atmospheric depth of 100 g cm-2 have been derived from aea level muon epectra at low and high latitudes. The derived epectra of pions and nucleons at low and high latitudes follow the relations N(Zn)dEn = 0.23 E,2.88dE, and N(Ep) dEp = 2.98 Ei2.eedEp per ,me eec str GeV in the energy range 16-1200 GeV. Below 16 GeV it ie found that the exponent of the energy spectrum ia very much dependent u n the incident energy and latitude of the location. The major difterence between low and highgtitude pion spectra can be explained in terme of geomagnetic effecta.
