Introduction This catalog provides the latest information for Hamamatsu ruggedized high temperature photomultiplier tubes ranging in diameter from 13 mm (1/2") to 51 mm (2"). All listed tubes employ high temperature bialkali photocathode that feature stable operation and long life at temperatures up to 90 °C, 175 °C or 200 °C. The electrode supporting structures have been designed so that tubes can be used in severe environments such as may be found in oil well logging, geological exploration, and aerospace applications. If you do not find the tube that meets your needs in this brochure, we will...
