Abstract
There is a proposal to construct a large neutrino detector in Korea, called Korean Neutrino Observatory (KNO), which consists of a large water tank and several tens of thousands of photosensors placed deep underground for neutrino detection. A 20-inch-diameter photosensor including a microchannel plate-photomultiplier Tube (MCP-PMT) is a candidate for the KNO due to its large photo-coverage. We characterized a 20-inch MCP-PMT by measuring its properties, including single photoelectron charge resolution, gain, signal-to-noise performance, dark count rate, after-pulse ratio, and timing performance. We present our measurements of its properties and compare them with those of a previous study.
