Design of MWPC-based muography measurements for geophysical research

 Muography is a most novel tool for geophysical density mapping. This
developing interdisciplinary research area is based on the detection of
muons originating from cosmic rays, allowing density-based non-destructive
investigations of the interior of objects up to the size of a mountain.
The cornerstone of the technology is that muons lose energy depending on
the density of the rock and the distance it travels through it. Thus, the
number and direction of the incoming muons can be used to determine
density anomalies (e.g. cavity, cave, ore) during data processing.

   Our Group in HUN-REN WignerRCP Budapest is internationally renowned in
the development of high-performance muon-detectors, data processing
procedures, and exploring new applications for muography.

   Recently we have developed a muographic-survey planning software, thus
for the various scenarios the optimal detector configuration and
orientations could be calculated.

   Reliability of this novel technology and any new equipments shall be
proven in well-known sites. The Jánossy Underground Laboratory (JURLab) in
Budapest is a simple-geometry multi-level underground infrastructure,
excellent for detector verifications and quantifying limits of underground
muographic surveys.

   We will present recent measurement series from JURLab campaigns;
validation of predicted yields with real data, and its implementation for
the tomographic inversion. Case studies and pilots from mining
applications will be shown.
