The Sudbury Neutrino Observatory will use an array of 9500 Hamamatsu R1480 8-in. photomultiplier tubes and their associated concentrators to detect Cherenkov light. This paper describes an experimental investigation of the photomultiplier tubes and their concentrators, together with work done to model the angular and wavelength response. Good agreement is(More)
This paper describes measurements made on Hamamatsu R1408 8-m. photomultiplier tubes in order to parameterise the cesium bialkali photocathode in terms of a complex refractive index fi and a thickness T. The extracted parameters have been used to predict the angular response of the photomultiplier tubes, and this prediction has been experimentally verified.(More)
