Searching for cavities in the Teotihuacan Pyramid of the Sun using cosmic muons ICRC-2011, Beijing, China

Archeology, geometry & location - Three man-made tunnels (1920-50): no internal structure. - Radón (1997) measurements: no large cavities (?) - Moon Pyramide (+2002 results): Internal structure and large tumb!

Geometry External shape Old digitalization AutoCad digitalization

Internal density

GEANT-4 simulation Hypothetical chamber Smith Tunnel SBD method

Detector design Components: - Scintillators - Multiwire PC’s - WFD readout - Telemetry

Detector

DAQ

Measured 2D

Substarction

Summary and outlook - Alvarez-type experiment in progress @ Teotihuacan - Detector installed and running (6 months) 1 M count report: Data & simulations are similar Difference shows artifacts, possibly related to geometry, location, and density uncertainties Too early to reach conclusions Plan to run, at least 12 more months
