Current Research

For the purpose of radiography, recent developments in muon and neutrino detectors make it possible to detect the muon and neutrino particles with high statistics and therefore in great detail. Because of their relevance for a variety of related fields of research, neutrino and muon physics will be a major focus in geophysical research. It is likely that several crucial questions concerning geodynamics and related fields such as volcanology and tectonics will be answered. The successful operation of such detectors, therefore, may very well represent the birth of a new technique for the study of fundamental issues in these fields.
