Description
We discuss flat panel multi-anode PMTs, micro-channel PMTs, Geiger APDs (SiPMTs), APD and other types of photodetectors.
We will discuss their performance but also problems including aging, and how to prevent it, their rate capability, and the effects of magnetic field.
We discuss various readout schemes, including pixel or strip line readout methods, the pixel charge sharing concept and its utilization to improve the resolution.
We discuss the detection efficiency, and new trends in the photocathode developments, and detector construction designs.
