Description
The performance of scintillator counters with embedded wavelength-shifting fibers
have been measured in the Fermilab Meson Test Beam Facility using 120 GeV protons.
The counters were extruded with a titanium dioxide surface coating and two channels
for the fibers at the Fermilab NICADD facility. Each fiber end is read out by a
$2{\times}2$ mm$^2$ silicon photomultiplier. The signals were amplified and
digitized by a custom-made front-end electronics board. Extrusions with
$5{\times}2$ cm$^2$ and $6{\times}2$ cm$^2$ profiles were tested, and with 1.4
and 1.8 mm diameter fibers. The design is intended to be used in the cosmic-ray
veto detector for the Mu2e experiment at Fermilab. The time response and light yield
as a function of the transverse and longitudinal position within the counters,
as well as incident beam angle, will be given.
