Photo multiplier is used to detect weak light. Q1: What does “weak” mean?

Scintillation light generated by radiation detector, such as Plastic scintillator, is very weak. PMT is used to detect such weak light. CHAPTER 2PMT BASIC PRINCIPLES OF 1)-5) PHOTOMULTIPLIERYou can learn PMT with “PMT handbook” TUBES from Hamamatsu, which is at http://www.hamamatsu.com/resources/pdf/etd/PMT_handbook_v3aE.pdf Figures on this text is copied from the handbook. A photomultiplier tube is a vacuum tube consisting of an input window, a photocathode, focusing electrodes, an electron multiplier and an anode usu- ally sealed into an evacuated glass tube. Figure 2-1 shows the schematic construction of a photomultiplier tube.

Figure 2-1: Construction of a photomultiplier tube 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 they are multiplied by means of secondary electron emission. This secondary emission is repeated at each of the successive dynodes. (4) The multiplied secondary electrons emitted from the last dynode are finally collected by the anode. This chapter describes the principles of photoelectron emission, electron tra- jectory, and the design and function of electron multipliers. The electron multipliers used for photomultiplier tubes are classified into two types: normal dis- crete dynodes consisting of multiple stages and continuous dynodes such as microchannel plates. Since both types of dynodes differ considerably in operating principle, photomultiplier tubes using microchannel plates (MCP-PMTs) are separately described in Chapter 10. Furthermore, electron multipliers for vari- ous particle beams and ion detectors are discussed in Chapter 12.

If metal electrodes are exposed to light, electrical sparks between them occur more readily. For this "photoelectric effect" to occur, the light waves must be above a certain frequency, however. According to physics theory, the light's intensity should be critical. In one of several epoch-making studies beginning in 1905, Albert Einstein explained that light consists of quanta - "packets" with ﬁxed energies corresponding to certain frequencies. One such light quantum, a photon, must have a certain minimum frequency before it can liberate an electron. https://www.nobelprize.org/nobel_prizes/physics/laureates/1921/einstein-facts.html

PMT is a device which can observe single photon. CHAPTER 2 BASIC PRINCIPLES OF PHOTOMULTIPLIER TUBES 1)-5)
