ROADSTR: a Mobile Antineutrino Detector Platform for enabling Multi-Reactor Spectrum, Oscillations and Application Measurements.

The aim of the Reactor Operations Antineutrino Detection Surface Testbed Rover (ROADSTR) project is to observe and monitor electron antineutrinos from nuclear reactors. ROADSTR has been designed as a readily mobile detector, allowing measurements at multiple sites using the same instrument. Besides the clear advantages towards nuclear safeguard and verification applications, an easily redeployable detector provides also a unique chance to contribute to flux and spectrum predictions for different nuclear fuels while minimizing the detector-related systematic uncertainties. Such measurements could prove crucial to understand the different anomalies spotted in the short baseline oscillation experiments, while providing benchmark measurements for different applications. The detection technology used for ROADSTR is 6Li doped plastics with Pulse Shape Discrimination capabilities. This type of technology has been primarily developed at the LLNL and the plastics are currently being produced in a larger scale by an external collaborator. This talk will focus on the testing framework designed to characterize the plastic elements and ensure its desired functionality and response.
