METHOD AND DEVICE FOR OBTAINING MUONOGRAPHY Russian patent published in 2010 - IPC F21H7/00 G03B42/00 G01T5/02 

FIELD: physics.

SUBSTANCE: muons of cosmic rays are simultaneously picked up from all directions of the celestial hemisphere first during a preparation phase and then during an exposure phase. The angle of arrival into the installation is calculated for each muon. The angular interval containing values of the obtained angle of arrival values is found. The number of muons in the found interval per unit is increased, thus filling the background and exposure matrix of multiple muons. Further, the filled matrix is used to calculate a matrix of relative variations of muons in different directions, which is then converted into an image representing muonography. In the device, the number, dimensions and relative position of detecting elements in coordinate planes are selected based on requirements which increase angular accuracy of reconstructing a muon track and the number of possible reconstructed directions, and the system for processing experimental information can calculate angles of arrival into the installation of each muon in real time.

EFFECT: high accuracy of reconstructing angles of arrival of muons into a detector and possibility of simultaneous measurement of streams of muons in all directions of the celestial hemisphere.
