  Muon radiography often referred to as muography, is an imaging technique that
uses freely available cosmic-ray muons to study the interior structure of
natural or man-made large-scale objects. The amount of multidisciplinary
applications of this technique keeps increasing over time and a variety of
basic detector types have already been used in the construction of muon
telescopes. Here, we are investigating the use of advanced gaseous detectors
for muography. As our basic solution, given its robustness and ease of
operation in remote, outdoor environments, a scintillator-based muon telescope
with silicon photomultiplier readout is being developed. To enhance the
telescope performance, we are proposing the use of Multi-gap Resistive Plate
Chambers (mRPCs) and Thick Gas Electron Multipliers (THGEMs). While the former
offer superior time resolution which could be beneficial for detector
background rejection, the latter detector type offers excellent spatial
resolution, can be manufactured at low cost and operated with a simple gas
mixture. Currently, prototype detector planes for each of these proposed types
are being designed and constructed, and initial performance tests are in
progress. In parallel, a Geant4- based muon telescope simulation is being
developed, which will enable us to e.g. optimize our telescope geometry and
study the use of superior time resolution for background rejection. The design
and status of the three detector prototype planes and the muon telescope, along
with the initial results of their performance tests and of the Geant4
simulation studies are reported.
