Claim 19:
20. A method for investigating material densities with a muon detection system, the method comprising method steps:
activating a muon detection apparatus by sending operational commands by using a processing unit;
receiving the operational commands by using a decentralized DAQ system comprising a surface part and a detector part;
sending operational parameters from the surface part of the DAQ system to the detector part of the DAQ system;
detecting in a muon detection apparatus located scintillation detector part emitted photons with a matrix detector, which emitted photons result from cosmic-ray induced muon particles passing via a plurality of intersecting muon trajectories through the material situated in the subsurface measurement volume of the muon detection apparatus;
processing the signals of detected photons into the form of a muon recording by using the DAQ system;
determining the position and orientation of the muon detection apparatus and producing position and orientation data of the muon detection apparatus by using a position and orientation apparatus;
sending the position and orientation data and muon recording from at least one muon detection apparatus via a communication hub device to the processing unit; and
processing at least one muon recording by using the processing unit, which processing steps comprise:
collecting at least one muon recording;
collecting the position and orientation data of at least one muon detection apparatus;
extracting density variations from the subsurface measurement volume by utilising at least one muon recording and position and orientation data of at least one muon detection apparatus; and
merging the extracted density variations from the subsurface measurement volume into a density distribution map.
