✦ Synopsis

New developments in photocathode, electron multiplier and photomultiplier tube (PMT) technologies are giving rise to new PMT designs that offer unique advantages for high luminosity and high energy physics experiments. Characteristics of the multianode PMTs (MA/PMTs) resulting from these new developments are discussed.

Fiber inputs from arrays of scintillators can be coupled to MA/PMTs to provide parallel signal detection in various sized arrays, e.g. 8 x 8 anode arrays in an 18 mm active diameter, to 177 anodes, spaced on 0.10 inch centers, within a 40 mm active diameter. These new detectors feature high counting efficiency, high peak-to-valley ratio, narrow pulse-height distribution and high data rates, as well as small size and insensitivity to magnetic fields. Detailed performance characteristics are discussed in this short review.
