What is the difference between the two, in that EM calorimeter will stop photons and electrons effectively wheras hadronic calorimeters stop hadrons effectively (but both do not seem to affect much muons)? What materials are used in each type?
One usually hears that the EM calorimeters interact electromagnetically whereas the hadronic calorimeters interact via the strong force. This is misleading since charged hadrons do interact electromagnetically, of course, and the em calorimeters contain nuclei which do interact via the strong force, so what makes something a good material for use in an em calorimeter or a good material for a hadronic calorimeter?
I know that the mass must be a key factor in explaining why charged hadrons do not interact much within the em calorimeters (they must interact *some* but apparently not much) but what explains the difference of interaction between the hadrons and the EM and hadronic calorimeters, respectively?
Thanks
