Advantages and disadvantages of different types of photomultiplier tubes (PMT) in the context of the gamma camera Tubes with GaP(Cs) The Tubes with GaP(Cs) is an example of a PMT. Fliyckt and Marmonier (2009) state that one of its advantages as the high secondary emission coefficient of the GaP(Cs) which enables it to reduce the unexpected fluctuations of gain in most PMTs and therefore, improving the energy resolution. This is especially beneficial for light pulses that can allow the cathode produce only a few electrons. Since the GaP(Cs) also has a dynode, it allow the viewer ...
