Title:
MUON-BASED NUCLEAR LEVEL SENSING GAUGE
Document Type and Number:
WIPO Patent Application WO/2020/205063
Kind Code:
A3
Abstract:
A disclosed system determines an amount and/or density of material in a container. The system includes a first detector, a second detector, and a processor circuit. The first detector and second detector determine a generally vertical flux of naturally-occurring charged particle entering and exiting the container, respectively. The first and second detectors may include scintillation detectors that detect muons in an energy range of 100-4000 MeV to determine a flux of muons entering the container and exiting the container, respectively. The processor circuit determines a difference in the flux of naturally-occurring charged particles entering the container relative to the flux of charged particles exiting the container. The processor circuit further determines the amount and/or density of material in the container based on the determined flux of charged particles lost by decay in the process materials or vessel walls or deflected from the second detector.
