Characteristics Of Multi-Anode Photomultiplier Tube For The Euso Focal Surface Detector

The focal surface of the EUSO telescope consists of a few hundred thousand of pixels of photo-detectors and detects air showers as mosaic images. The strongest requirement for the focal surface detector is the maximization of the photon detection efficiency together with the uniformity over the focal surface. We have developed a new type of multi-anode photomultiplier tube (MAPMT). The tatal photon detection efficiency has improved than before by about 2.1 times.
