Large Plastic Scintillator Panels with WLS Fiber Readout; Optimization of Components

Understand

Results are presented on R&D efforts to design and build large size veto panels, optimized for underground low background experiments, in the most efficient and economical way using commercially available components.

• A variety of plastic scintillators, photomultiplier tubes, wavelength shifting fibers, and light reflector combinations were tested.
• Results of these studies and performance of a 2.2 meter long panel are presented.
