Description
There is a proposal to construct a large Korea Neutrino observatory (KNO) in Korea. It consists of a large water tank and several tens of thousands of photosensors to detect neutrinos. We have been testing a 20-inch Micro Channel Plate Photomultiplier Tube (MCP-PMT) to determine whether the MCP-PMTs are suitable photosensors for the KNO. The important properties of the MCP-PMT such as gain, linearity, energy resolution, peak to valley ratio, signal to noise ratio, dark rate, rising and falling time of single photo-electron, after pulse ratio and dark rate change with temperature are investigated and the results will be presented.
