A photomultipler with an S20 photocathode has a chain of eight dynodes that provide a gain of 2 × 106 at the operating voltage of 2 kV. Light of wavelength 700 nm and power 7 nW is incident on the photocathode. (a) For each electron incident on one of the dynodes, determine the average number of electrons leaving that dynode and moving on to the next one. (b) Determine the voltage difference between dynodes, and the kinetic energy that the electrons pick up in moving from one dynode to the next. (c) Determine the anode current and the voltage across the 1 kload resistor. (d) Repeat part c if the wavelength is shifted to 600 nm with the same optical power.
