Ground?level muon flux variation in a cosmic ray simulation

Simulation of Cosmic Ray Muon Flux at Shallow Depths Underground

Geant4 has been used to estimate the rate, energy spectrum and angular distribution of cosmic ray muons at underground depths between 300 and 1000 m.w.e. The results agree well with those from the MUSIC program when the same surface spectrum is used. Care has been taken to use a parameterization of the surface spectrum which agrees well with data for the relevant energies. 1 Goals Knowledge of ...

The Cosmic Ray Muon Flux at WIPP

In this work a measurement of the muon intensity at the Waste Isolation Pilot Plant (WIPP) near Carlsbad, NM, USA is presented. WIPP is a salt mine with a depth of 655 m. The vertical muon flux was measured with a two panels scintillator coincidence setup to Φvert = (3.10 +0.05 −0.07) 10 −7 s−1cm−2sr−1.

Cosmic Ray Muon Physics

We present a review of atmospheric and underground muon flux measurements. The relevance of these data for the atmospheric neutrino flux computation is emphasized. Possible sources of systematic errors in the measurements are discussed, focusing on the sea level muon data. Underground muon data are also reported.

Cosmic-ray Muon Radiography of a Volcano

The origin and structure of the Earth's crust is still a major question. Traditionally the nearby crust of the Earth has been explored in great detail with echo-sounding or gravimetric techniques. Current measurements are based largely on these techniques, which has intrinsic uncertainties. In the present talk, a novel method with cosmic-ray muons to create a direct snapshot of the density prof...
