Resumen:

We use the SciCRT as a new muon detector and fill a gap remaining in the viewing directions of the present GMDN over the north and middle America. In order to minimize the data acquisition time, we trigger the muon measurement by the four-fold coincidence of hit signals from the top and bottom pairs of the X- and Y-layers and identify the location of muon on each layer by choosing the scintillator bar yielding the maximum ADC count in each layer. By analyzing the cosmic ray data observed by a full-scale SciCRT detector assembled for the test operation in the Instituto Nacional de Astrofisica, Optica y Electronica (INAOE) in Mexico, we confirm that more than 95 % of muon trigger events are successfully recorded with their correct incident directions. The angular resolution of the muon incident direction is also evaluated to be ~ 3°.
