the main detector of a scintillation counter depends on the calculating factor that you depict on using in your scintillation.
Neutrons from fission have a natural energy of about 2 Mev. In a thermal reactor these are slowed to thermal equilibrium by a moderator, at about 0.025 ev. At these lower energies (= slower speeds) we have more time to have them react with a measuring device, commonly a particle detector. Or a scintillation detector with associated light detector..

The Scintillation Counter uses a gas-filled metal tube.The Geiger Counter uses a phosphor-coated surface.

It is a telescope that uses lenses and mirrors.
the reflecting telescope uses mirrors and lenses. The refracting telescope does not include the mirrors.

A reflecting telescope uses mirrors while refracting telescopes uses lens. The refracting telescope also had chromatic aberration and bad resolution while the reflecting telescope had none of these.
