Photomultiplier tube of new dynode configuration

In spectroscopic analysis, radiation detection, and medical application fields, portable instruments requiring high accuracy and high sensitivity are being developed. Since conventional photomultiplier tube (PMT) envelopes are made of glass and are large in size, it is difficult to downsize instruments. PMTs are mainly used for high accuracy instruments, while solid state detectors are employed for general purpose, or compact instruments. Hamamatsu recently developed the compact PMT R5600 series, which is downsized to the same dimensions as a solid state detector while maintaining the same performance, high sensitivity and high speed as the conventional PMTs. >
