Ne~ experimental results on muon-catalyzed d-t fusion are reported. Unexpected target-density effects have been discovered both in dt p, molecular formation in t p, + 02 collisions and in the effective sticking probability. The dt p. formation rate is significantly enhanced at high density, presumably because of a strong three-body contribution. The origin of the observed reduction of the stick...

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...

Imaging and identifying materials with high atomic numbers and densities, especially radioactive materials, is one of the issues that have been especially considered in recent years. Due to some limitations in conventional and old imaging techniques, finding an alternative method is very important. The cosmic muons with an infinite source are one of the sources that have been recently studied f...

In this note we outline a procedure for determining the mass density of material surrounding the muon detector by comparing measured muon fluxes with reference or background data-sets and adjusting a set of parameters which describe the density to achieve a best overall agreement between signal and background fluxes. Information on muon fluxes is stored in “data-cubes” which are histograms givi...

Seasonal Variations in Muon Rate are caused by large scale changes in atmospheric conditions throughout the year. As atmospheric temperature and density vary across the seasons, so do the absorption rates of cosmic ray secondaries in the atmosphere. The IceCube neutrino detector array can track both large and small scale variations in atmospheric muon rate and daily, detailed weather data is av...

The average mass composition of cosmic rays with primary energies between 10(17) and 10(18) eV has been studied using a hybrid detector consisting of the High Resolution Fly's Eye (HiRes) prototype and the MIA muon array. Measurements have been made of the change in the depth of shower maximum and the muon density as a function of energy. The results show that the composition is changing from a...

The International Muon Ionization Cooling Experiment (MICE) is devoted to a study of a muon cooling channel capable of giving the desired performance for a Neutrino Factory. One of the goals is achieving an absolute accuracy of measurements of emittance reduction as high as ±0.1%. The paper describes results of a Monte Carlo study on allowed density variations of liquid hydrogen corresponding t...

  In the present work, the fundamental behavior of four body molecule formations of pt μμ , pd μμ , dt μμ , tt μμ , and pp μμ in a D/T fusion are considered. Their higher fusion rate, specially the available data for dt μμ , encouraged us to study the muon cycling rate in D/T fusion in the temperature range of (100-1400 K), density and deuterium-tritium concentration ratio. For this purpose, va...

Usage of secondary cosmic muons to image the geological structures density distribution significantly developed during the past ten years. Recent applications demonstrate the method interest to monitor magma ascent and volcanic gas movements inside volcanoes. Muon radiography could be used to monitor density variations in aquifers and the critical zone in the near surface. However, the time res...
