Abstract
Abstract
Polyethylene Naphthalate (PEN) plastic scintillator has been
identified as potential self-vetoing structural material in
low-background physics experiments. Radio-pure scintillating
components have been produced from PEN using injection compression
molding technology. These low-background PEN components will be used
as optically active holders to mount the Germanium detectors in the
Legend-200 neutrinoless double beta decay experiment. In
this paper, we present the measurement of the optical properties of
these PEN components. The scintillation light emission spectrum,
time constant, attenuation and bulk absorption length as well as
light output and light yield are reported. In addition, the surface
of these PEN components has been characterized and an estimation of
the surface roughness is presented. The light output of the final
Legend-200 detector holders has been measured and is
reported. These measurements were used to estimate the self-vetoing
efficiency of these holders.
