I believe most particle detectors are based on either the photoelectric effect, or simply on excitation of atoms by light. Then, the energy resulting from this process is converted into something we associate with the detection of a particle/field excitation. If that is the case, every field/particle we measure has to be measured indirectly by measuring the electromagnetic field.
My question is the following: Are there other ways of measuring particles/fields that does not involve measuring the EM field? If so, I'd love to hear some examples.
