Production of Radiopure Materials
- Yuri Efremenko (University of Tennessee)
High purity copper continues to play an important role for ultra-low-background detectors on neutrino physics and dark matter experiments. Electroforming of copper is an electrochemical process that enables the manufacture of metallic parts with high chemical and radioactive purity, process reproducibility and good mechanical properties.
To support the construction of the ultra-low-background...
Achieving the scientific goals of rare-event searches, such as dark matter and neutrinoless double-beta decay detection, hinges on stringent background reduction. Utilizing materials with outstanding radiopurity that can additionally self-veto internal background radiation is critical for meeting these requirements. Poly(ethylene-2,6-naphthalate) (PEN) has emerged as a highly promising...
Near-future low-background experiments such as direct Dark Matter (DM) or Neutrinoless Double-Beta Decay search experiments require extremely radiopure detector materials and consistent manufacturing processes to achieve their physics discovery potential. Electroformed copper (EFCu) has been shown to achieve extreme radiopurity. However, its mechanical properties are limited due to high...
RES-NOVA is a newly funded project for the investigation of astrophysical neutrino sources with archaeological PbWO4 cryogenic detectors. RES-NOVA will exploit Coherent Elastic neutrino-Nucleus Scattering (CEνNS) as detection channel, thus it will be equally sensitive to all neutrino flavors produced by Supernovae.
In order to achieve the goal sensitivity, the crystal must be grown from...
