Abstract
Neutrino Observatory in the Nanhai (NEON) is a proposed cubic-kilometre scale high-energy neutrino observatory located in the South China Sea. The observatory consists of tens of thousands of optical modules (OMs), where photomultiplier tubes (PMTs) are equipped, for capturing Cherenkov light produced by secondary particles of neutrino interactions with Earth. Each OM consists of over thirty 3-inch PMTs. In this work, we measure the characteristics of two types of PMTs, Hamamatsu R14374 and NVN N2032, including their dark count rates, gain, quantum efficiency, and peak-to-valley ratio. All measured parameters will be compared according to the requirements of our scientific goals.
