Description
As cosmic muons traverse a target they interact with it (eg. bremsstrahlung,..) that induces a secondary radiation, whose spectra depends on the material-composition of the target. This imaging technique is sensitive to low-Z materials as well, opening a novel non-invasive material-identification method for medium-sized obscure targets.
Our Hungarian-Serbian collaboration pioneered in demonstrating experimentally this unique method, using gaseous trackers for the muons, and scintillator array and germanium for the secondaries. Results have proven imaging possibility ranging from metals to soft-tissue targets. Corresponding Geant4 simulations have counseled upgrades on forward-sideward asymmetry and sensitivity to the electron/gamma ratio. The former got materialized in a new experimental setup, with large-coverage segmented scinitallators arrays, and a compact and detailed DAQ, with electron-tagging possibility.
The presentation will describe the recent results in imaging via secondaries, discuss the visible limitations, and detail the new enhanced experimental setup, and its first results.
