First Steps Towards a Muon Bunker Telescope to Verify the Absence of Nuclear Weapons — •Alexandra Datz¹ and Moritz Kütt^1,2 — ¹Institute for Peace Research and Security Policy at the University of Hamburg — ²Program on Science and Security, Princeton University

Measurement approaches to verify the absence (or presence) of fissile materials are currently under intensive investigation. Through such measurements, one can demonstrate the absence of nuclear weapons. Previous measurements relied on particles emitted by the nuclear weapons themselves, photons and neutrons. We propose a new approach, using cosmic-ray-induced muons (muography), and a single detector to find hidden fissile material in potential nuclear weapon deployment sites (e.g. bunkers). Our contribution will present the possible framework for the application of this method to find hidden significant quantities of plutonium or highly-enriched uranium. Additionally, we show simulation results illustrating necessary detector properties and measurement times for a practical application.
