| Conventional muon radiography has concentrated on non-destructive studies of
stationary objects with relatively long exposure times required to achieve
sufficient muon statistics. A muon detection system with real time readings
and a high spatial resolution detector, enables the investigation of dynamic
processes in a stroboscopic mode, where image frames are synchronized with
the phases of the dynamic target. Although the natural cosmic ray muon flux
is quite low for imaging a rapid process, repetitive processes can still be
studied with high time resolution by integrating a large number of frames
synchronized to the process. In this paper we demonstrate the stroboscopic
imaging capabilities of cosmic ray muon radiography with scintillation
counters and the muon readout module. The dynamics of a chemical and melting
process in an electric furnace with a size of 30 m water equivalent in
diameter was investigated as an example, and stroboscopic images were
obtained for hourly changes, with acquisition frames of 400 h each. The
results of these experiments demonstrate the future potential for muon
radiography of repetitional process, such as magma flow in a conduit. |
