Hi, I'm starting a prac on muon lifetimes and we have been asked to calculate the range of energies suitable for the experiment... Thinking about this, I was a bit stumped as to what we were supposed to be calculating... Is this a limitation of the detection equipment? Or do low energy muons never make it to earth? and high energy muons are too fast to detect? These are the only other reasons I could come up with! Any help would be greatly appreciated! Thanks!
