Improvement of 20 in. diameter photomultiplier tubes
The quality of the 20 in . photomultiplier tubes (Hamamatsu R1449) has been greatly improved over the required specifications for using them m the 50000 ton imaging water Cherenkov detector, Super-Kamiokande . In particular, the resolution of the timing response for single-photoelectron light has been reduced to 3 ns (1Q width), and a clear single-photoelectron peak can be seen in the pulse hei...
متن کاملPhotomultiplier Tubes
Light which enters a photomultiplier tube is detected and produces an output signal through the following processes. (1) Light passes through the input window. (2) Light excites the electrons in the photocathode so that photoelectrons are emitted into the vacuum (external photoelectric effect). (3) Photoelectrons are accelerated and focused by the focusing electrode onto the first dynode where ...

including basic and performance. For example, section 4.1 shows spectral response characteristics of typical photocathodes and also gives the definition of photocathode sensitivity and its measurement procedure. Section 4.2 explains dynode types, structures and typical characteristics. Section 4.3 describes various performance characteristics such as time response, operating stability, sensitiv...
متن کاملCharacterization of the New R5900 Hamamatsu Photomultiplier in Pisa
We report on a wide program of tests of the new conception Hama-matsu photomultiplier R5900. Fifteen of such photomultipliers have been characterized in Pisa testing their main parameters with a dedicated setup. Such a test program has been carried out in the framework of the study of a realistic prototype of the future ATLAS tile hadronic calorimeter (TILECAL).
