In this paper we present the
fabrication, testing and initial calibration system for scintillator
modules to be
used as muon counters for cosmic ray particle shower
detection, developed in the ITeDA facilities. Each muon counter
has
an area of 30 m2 , divided in three scintillator modules of 10 m2 ,
and is made of plastic scintillator strips with doped
optical fibers
glued to them, which guide the light to 64 pixel photomultiplier
tubes. Each module is buried to detect
only the muon component of
the cosmic shower. The scintillator modules are tested with a
scanner that consists of an
x − y positioning system that
moves a 5 mCi 137 Cs radioactive source over the module taking data
at fixed locations.
The scanner both tests the module for
possible fabrication defects and stores the light-attenuation curve
parameters. A
complete description and specifications of the
fabrication process and materials used for the construction of the
scintillator
modules is presented. Also, a complete scanning process
of a 64 strip scintillator module is performed and results are
presented and compared with an initial calibration performed with a
muon telescope.
