| Zusammenfassung |
| The cosmic ray muon tomography gives an access to the density structure of
geological targets. In the present article we describe a muon telescope
adapted to harsh environmental conditions. In particular the design optimizes
the total weight and power consumption to ease the deployment and increase
the autonomy of the detector. The muon telescopes consist of at least two
scintillator detection matrices readout by photosensors via optical fibres.
Two photosensor options have been studied. The baseline option foresees one
multianode photomultiplier (MAPM) per matrix. A second option using one
multipixel photon counter (MPPC) per bar is under development. The readout
electronics and data acquisition system developed for both options are
detailed. We present a first data set acquired in open-sky conditions
compared with the muon flux detected across geological objects. |
