First Demonstration of Underground Muon Imaging at an Archaeological Site in Ancient Jerusalem

Abstract

We present a novel underground imaging system that utilizes cosmic-ray muons to explore the subsurface environment at the City of David archaeological site in ancient Jerusalem. This report details the initial findings from measurements conducted at a large cistern, commonly called "Jeremiah's cistern" (referenced in Jeremiah 38:6). The system aims to locate and map hidden voids and structural anomalies within the overburden. Our primary outcome is the derivation of the angular ground depth, which serves as a proxy for understanding the integrated density distribution of the overburden. This work represents a significant interdisciplinary effort to deepen our understanding of this historically important site.
