				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?
