“…The value of α T is then determined by comparing the effective temperature determined from a single ECMWF temperature measurement to the corresponding six hours of MINOS muon data (AE3 hours on either side). The effect of surface pressure on the muon rate was investigated and found to be small [21,22]. It had no impact on the measurement of α T and is therefore not considered further.…”

A sample of 1.53 × 10 9 cosmic-ray-induced single muon events has been recorded at 225 m water equivalent using the MINOS near detector. The underground muon rate is observed to be highly correlated with the effective atmospheric temperature. The coefficient α T , relating the change in the muon rate to the change in the vertical effective temperature, is determined to be 0.428 AE 0.003ðstat:Þ AE 0.059ðsyst:Þ. An alternative description is provided by the weighted effective temperature, introduced to account for the differences in the temperature profile and muon flux as a function of zenith angle. Using the latter estimation of temperature, the coefficient is determined to be 0.352 AE 0.003ðstat:Þ AE 0.046ðsyst:Þ.

Muons comprise an important contribution of the natural radiation dose in air (approx. 30 nSv/h of a total dose rate of 65-130 nSv/h), as well as in underground sites even when the flux and relative contribution are significantly reduced. The flux of the muons observed in underground can be used as an estimator for the depth in mwe (meter water equivalent) of the underground site. The water equivalent depth is an important information to devise physics experiments feasible for a specific site. A mobile detector for performing measurements of the muon's flux was developed in IFIN-HH, Bucharest. Consisting of 2 scintillator plates (approx. 0.9 m 2 ) which measure in coincidence, the detector is installed on a van which facilitates measurements at different locations at surface or underground. The detector was used to determine muon fluxes at different sites in Romania. In particular, data were taken and the values of meter water equivalents were assessed for several locations from the salt mine from Slanic Prahova, Romania. The measurements have been performed in 2 different galleries of the Slanic mine at different depths. In order to test the stability of the method, also measurements of the muon flux at surface at different elevations were performed. The results were compared with predictions of Monte-Carlo simulations using the CORSIKA and MUSIC codes.

“…The overall uncertainties in the measurements were less than 5 % for protons and 10 % for helium nuclei. The absolute flux of atmospheric muons was measured from 0.6 to 20 GeV/c at sea level [7] and from 0.6 to 100 GeV/c at a mountain altitude [8]. The overall uncertainty in the measurements was less than 10 %.…”

Primary and atmospheric cosmic-ray spectra were precisely measured with the BESS-TeV spectrometer. The spectrometer was upgraded from BESS-98 to achieve seven times higher resolution in momentum measurement. We report absolute fluxes of primary protons and helium nuclei in the energy ranges, 1-540 GeV and 1-250 GeV/n, respectively, and absolute flux of atmospheric muons in the momentum range 0.6-400 GeV/c.
