| Abstract | Muon tomography based on Multiple Coulomb Scattering of cosmic ray muons appears as a promising way to distinguish high-Z threat materials such as U or Pu from low-Z and medium-Z background with high statistical significance. We have constructed a first MT station prototype with 30 cm × 30 cm large GEMs to demonstrate the validity of using MPGDs as the muon tracking stations for muon tomography. A total of 8 detectors were assembled, 6 of them were tested successfully so far. Preliminary tests on the detector performances show expected and similar behavior for gains, rate plateaus, and charge-sharing among readout strips when tested with X-rays. Initial tests of the MT station showed that the communication between the VME DAQ hardware and the software is working properly. We are studying the data collected with an empty MT station and with the iron and lead targets. We are planning to use the APV-25 chip for the front-end electronics of the full prototype. |
