WebbThe photomultiplier tube output in the photon counting mode is extremely small. This requires a photomulti-plier tube having a high gain and an amplifier with suf-ficiently low noise relative to the photomultiplier tube output noise. As a general guide, photomultiplier tubes should have a gain of approximately 1 × 106 or more. Webb31 okt. 2024 · Oct 30, 2024 at 22:27. 1.
