Why first photon emits two electrons in a photomultiplier tube? The interaction is one photon with one electron, am i right?
Thanks in advance.

The photoelectric effect is just the first step. That first emitted electron is then slammed into plates which causes several additional electrons to be emitted. (The latter effect is called secondary emission.)
