Description
Over the last decade, IRFU's muography team at CEA-Saclay has actively developed and upgraded compact muon telescopes based on multiplexed resistive Mesh Gaseous Structure (Micromegas) detectors. This technology developed at CEA has allowed high-resolution imaging surveys to be conducted in the field for applications ranging from archaeology (ScanPyramids project) to nuclear surveillance, particularly in demand for non-invasive high-penetrating methods to probe shielded structures.
Current muography projects at IRFU are drawn towards this sector, notably focused on nuclear reactor three-dimensional tomography and characterization of nuclear waste containers.
This presentation will cover recent muon survey developments, including field studies within CEA’s nuclear waste storage facilities and a proof-of-concept imaging project targeting nuclear storage barrels. Each survey applies distinct muon imaging techniques and detection configurations. To identify density anomalies in the scanned structure, the obtained muon images are put in comparison to GEANT4 simulations, reproducing the expected geometry of the investigated object along with the detection setup.
