A key task for customs workers is the interception of hazardous, illegal and counterfeit items in order to protect health safety citizens. However, it estimated that only a small fraction cargo inspected an even smaller trafficked goods are detected. Today, most widely used technology scanning vehicles, ranging from vans trucks railcars, γ ray X-ray radiography. New technologies required overcome current technological shortcomings, such as inability detect target material composition, usage...
The full optimization of the design and operation instruments whose functioning relies on interaction radiation with matter is a super-human task, due to large dimensionality space possible choices for geometry, detection technology, materials, data-acquisition, information-extraction techniques, interdependence related parameters. On other hand, massive potential gains in performance over standard, "experience-driven" layouts are principle within our reach if an objective function fully...
Abstract We describe a software package, TomOpt, developed to optimise the geometrical layout and specifications of detectors designed for tomography by scattering cosmic-ray muons.

In doing so, we provide first demonstration end-to-end-differentiable inference-aware particle physics instruments. study performance on relevant...
Muon tomography leverages the small, continuous flux of cosmic rays produced in upper atmosphere to measure density unknown volumes. The multiple Coulomb scattering that muons undergo when passing through material can either be leveraged or represent a measurement nuisance. In case, dependence on muon momentum is significant source imprecision. This alleviated by including dedicated devices experiment, which have potential cost and interfere with measurement. An alternative consists...
The TomOpt software package is designed to optimise the geometric configuration and specifications of detectors intended for muon scattering tomography, an imaging technique exploiting cosmic-ray muons. employs end-to-end differentiable pipeline that models interactions muons with scanned volumes, infers properties materials, performs optimisation cycle minimising a user-defined loss function. This article presents implementation case study related cargo scanning applications in context...
Non-destructive subsurface imaging methods based on the absorption or scattering of photons neutrons are becoming increasingly popular in cultural asset conservation. However, these techniques limited by physical and practical issues: their penetration depth may be insufficient for large items, they usually necessitate transferring objects interest to specialised laboratories. The latter issue is recently being addressed development portable sources, but artificial radiation can harmful thus...
