		How do photomultipliers work
		Why are photomultipliers offered with different pin configurations?
		Will a photomultiplier exposed to ambient light, while on, be permanently damaged?
		Can I store photomultipliers for a long time?
		I have an old photomultiplier. How can I easily find out if it is in working order?
		What photomultipliers do you recommend for low and stable dark count?
		Can I use a laser as input to a photomultiplier?

		How do I deal with too much signal from a photomultiplier?
		How many photoelectrons will my 100 µJ laser produce from a typical photomultiplier?
		Why is my signal saturated?
		What is the difference between having an anode load or no anode load?
		What is the meaning of A/lm and how does it relate to the applied high voltage?
		What is the significance of nominal A/lm?
		How do I keep the signal from vanishing whilst cooling my extended red response photomultiplier to decrease the dark count (aka background)?

		Why do I get negative values when photon counting?
		What is the best dynode structure for photon counting?
		How can I optimise my photomultiplier for photon counting?

		What are the most important factors in choosing a photomultiplier for scintillation counting?
		What is the relationship between the energy of the x-rays and the number of photons or photoelectrons produced?
		Do you have any documents with background information and application notes which explain how to design systems with the tubes?
