Abstract

Lingacom Ltd develops detectors for muography-imaging using cosmic-ray muons-together with imaging algorithms and tools. We present selected simulation results from muon imaging of cargo conta- iners, from a joint muon and X-ray imaging algorithm, and for ground surveys using borehole detectors.This article is part of the Theo Murphy meeting issue 'Cosmic-ray muography'.

Keywords: X-ray; imaging; muography; muons.

A simple gas detector prototype used in the stability test. Additional fast ionizing-particle ‘trigger’ detectors used to confirm well-timed signals from the gas detector are located below the desk and are not visible in this photo. (Online version in colour.)

Figure 3.
The rate of confirmed triggers from the sealed gas detector of figure 2 as a function of time. The sudden jumps in rates are due to changes in the location of the stability test set-up and to changes in the location of the gas detector relative to the trigger detectors. (Online version in colour.)

Concept of operations—an X-ray scan serves as a primary system and dense cargo is passed to a muon scanner serving as a secondary system. (Online version in colour.)
