Muon Scattering Tomography For Inventory Verification In Arms Control

The verification of declarations made about an inventory of fissile material stocks will form a key aspect of any future nuclear weapon treaty. The ability to confirm, in a treaty accountable item, the presence or absence of some identifying characteristic forms the basis of a testable declaration. To be able to do so passively, and without revealing detailed information about the contents, presents an attractive verification method. We present the initial results of a viability study into Muon Scattering Tomography (MST) for use in a such manner. Employing a templating approach, our study uses MST to identify changes in geometries inside sealed containers, whilst protecting sensitive data. The study is based on Geant4 simulations and provides some promising results.
