Experimental results
Attenuation Length Measurements
Measurements of the Light Attenuation Length (LAL) [6] show that the value of
the long and short components is 42.15 1.14 cm and 30.52 0.74 cm, respectively.
The extruded scintillator samples were wrapped in Tyvek since they did not have the
co-extruded reflective coating. In order to evaluate the impact of the TiO2 coating, a
comparative study was performed using 1 m long triangular strips. The results are
shown on Fig. 4.4
