Link to Dukes Google Drive folder for NAUM.

Non-invasive Archeology using Muons, or NAUM, is an experiment designed to probe the Temple of Kukulkan (or El Castillo) at Chichen Itza. We are a collaboration of Chicago State University, Dominican University, the National Autonomous University of Mexico, the University of Illinois Chicago, and the Instituto Nacional de Antropologia e Historia.

The UVA group designed and fabricated the detector modules. Each module consists of an x- and y-plane of triangular scintillation counters. Three modules form a detector, one of which is at the Chichen Itza site, the other is at Chicago.

The detector was installed in the pyramid in late January, 2026 and is currently taking data.
