The increase of the light collection from scintillation strip with hole for WLS fiber using various types of fillers

The light collection of the extruded scintillator strip samples with WLS fibers placed in the longitudinal hole in the plates was measured. The holes were filled with various liquid fillers. Measurements were carried out under irradiation by cosmic muons. The method of pumping liquid filler with viscosity more than 10 Pa*s in the strip hole with WLS fiber inside was designed and successfully tested.

Optimization of light yield by injection of the optical filler into the co extruded hole of plastic scintillation bar with WLS fiber in it

Results of the measurements with cosmic muons for the light yield of 2-meter long extruded scintillation bar (strip) as a function of distance for different options for light collection technique are presented. Scintillation strip cross section geometry was a triangle made on polystyrene plastic scintillator with dopants of 2% PTP and 0.03% POPOP, extruded with 2.6 mm diameter hole and produced at ISMA (Kharkov, Ukraine). It was shown that the insertion of the optical transparent resin (BC 600 or CKTN MED(E)) by special technique into the co-extruded hole with 1.0 mm or 1.2 mm wave-length shifter (WLS) fiber Kuraray Y11 (200) MC in it significantly improves light collection by factor of 1.6...1.9 against of the 'dry' case.
