Description
The recent development of very fast, automated scanning microscopes has made possible the application of nuclear emulsion detectors in large physics experiments, as well as in new interesting fields such as muon radiography of volcanoes. Muon radiography exploits the same basic principle as the standard medical radiography: it measures the absorption of quasi-horizontal cosmic-ray muons when traversing the edifice of a volcano, thus showing its internal structure in an average density map.
Nuclear emulsion films represent a very interesting detector due to their high spatial (< 1 µm) and angular resolution (a few mrads), compactness and robustness. Moreover, they don't require electric power supply, are easily transportable on a mountain and do not require infrastructure.
Here, we present the application of the nuclear emulsion technique to the muon radiography of Unzen and Stromboli volcanoes. We report preliminary results on a partial sample of emulsion films exposed in Japan at the Unzen mount. Futhermore we will describe the emulsion detector exposed at Stromboli and present a first look at their data.
