Description
Progress in the fields of neutrino physics and dark matter searches have placed extreme demands for ultra-low background sensitivities. These improvements can be achieved by replacing inactive structural components with transparent, radio-pure plastic scintillators. These structural scintillating components can serve as an active veto, discriminating internal events of interest from external background events. Poly(ethylene-2,6-naphthalate) (PEN) has been identified as an ideal material for structural scintillator components as it has a significant yield strength at cryogenic temperatures, functions as a wavelength shifter for liquid argon-based detectors, scintillating in the 400 nm region. This presentation will describe efforts to produce and characterize low background components for rare event physics experiments and will provide an update on the synthesis efforts of PEN and PEN derivatives at Oak Ridge National Laboratory.
