The Super-SANDI nylon vessel: Compatibility with Water-based Liquid Scintillator — •Noah Goehlke, Amala Augusthy, Johann Martyn, Philipp Kern, Michael Wurm, David Maksimovic, and Oliver Pilarczyk — Johannes Gutenberg-Universität Mainz
The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) is a neutrino detector at the Booster Neutrino Beam at Fermilab, designed for measuring the neutron multiplicity in neutrino-nucleus interactions. ANNIE has a strong focus on testing new detector technologies, among which is Water-based Liquid Scintillator (WbLS). WbLS is a novel detection medium, consisting of liquid scintillator dissolved in water with the help of a surfactant. It allows for the simultaneous observation of Cherenkov and scintillation light. To test the reconstruction of extended event topologies in WbLS, ANNIE is going to deploy a nylon vessel containing 8 m3 of WbLS (dubbed Super-SANDI) this summer. In preparation for Super-SANDI, the chemical compatibility between WbLS and different types of Nylon was investigated. UVvis spectroscopy was used to study the effects on the transparency and on the organic components of the WbLS after exposure to Nylon for an extended period of time. While the transparency is unaffected, an adsorption of PPO into nylon was found, creating slightly scintillating nylon.
