MUON TOMOGRAPHY - TIMELINE

$/!\$ UNDER MAINTENANCE $/!\$

(This page will contain a timeline of important events and reference works in the area of muon tomography)

1912

Cosmic Rays Discovery
Austrian physicist Victor F. Hess discovers cosmic-rays in a series of ascents in a hot-air balloon while looking for the source of the ionization radiation observed in the ground and in the atmosphere. His highest ascent was at 5.3 km of altitude.

1936

Muon Discovery
American physicist Carl D. Anderson and his graduate student Seth Neddermeyer discovered the existence of muon particles. The first observation of a muon was in a cosmic-ray.

1955

First Use of Muons
First reported use of cosmic-ray muons by Eric George to measure ice thickness above a tunnel in Australia.

1967

Muon Radiography in Chephren Pyramid
Muon radiography is used by Luis Alvarez team to look for hidden chambers in Chephren Pyramid in Egypt. No additional chambers were found at that time.

1987

Measurement Depth of Nagoya Subway Tunnels
Minato et al. measure the depths of Nagoya subway tunnels using cosmic-ray muons.

1999

Moon Shadow is Imaged using Muons
At the Soudan II detector in Minnesota, at an undergroud depth of 700m, the Moon shadow is imaged using muon flux.

2003

Preparation to Inspect the Pyramid of the Sun
The beginning preparations on a muon detector system are iniciated to inspect the interior of the Pyramid of the Sun in Mexico.

Beginning Applications of Muon Scattering Tomography
At LANL, a seminal work on utilising Coulomb scattering of muons to identify high-Z objects is made aiming the detection of nuclear treats.
