Abstract:
The Mitchell Institute Neutrino Experiment at Reactor (MINER) at Texas A$\&$M University, USA is a reactor based neutrino experiment which aims to measure coherent elastic neutrino-nucleus scattering (CE$\nu$NS) where a neutrino interacts with a nucleus as a whole creating a nuclear recoil [1, 2]. One of the main challenges for this experiment is to deploy detectors capable of measuring low-recoil energies. A novel sapphire detector made up of Al$_{2}$O$_{3}$ substrate with dimension 7.62 mm $\times$ 4 mm with mass 73 g has been fabricated and characterized. Particle interactions are detected through phonons and scintillation photons. The phonons are detected through Transition edge sensors (TES) photo-lithographically placed on the surface of the detector. The photons are detected through their interactions with a Si HV [3] detector in coincidence. We will report the characterization and performance of the sapphire detector in reactor and non-reactor environments.
