METHOD OF CALIBRATING MUON HODOSCOPES Russian patent published in 2012 - IPC G21H7/00 

FIELD: physics.

SUBSTANCE: external independent detection of muon tracks is carried out from all directions of the celestial hemisphere passing through the hodoscope which is placed between two flat coordinate detectors lying parallel to each other in the horizontal plane. Both coordinate detectors are connected to a controller through a coincidence circuit. Outputs from all detecting layers of the hodoscope are connected to the same controller. When a signal from the coincidence circuit reaches the controller, the controller reads coordinates of the passing muon from all layers of the hodoscope. The controller transmits to a computer information on the track of the muon passing through coordinate detectors and the corresponding information from the hodoscope. As a result, efficiency of operation of separate channels of the hodoscope is evaluated. Simultaneously, spacial-angular distribution of the stream of muons passing through the coordinate planes is constructed and then compared with distributions obtained from the muon hodoscope.

EFFECT: possibility of simultaneous calibration of a large number of channels, not for one layer, but for the entire hodoscope.
