The Tube-based Preamplifier is a low noise, high performance, tube-based charge-sensitive preamplifier,  or voltage-sensitive preamplifier.

It is connected to 8-stage or 10-stage multiplier structure photomultiplier tube  (PMT), which can be used to match various scintillation detectors, such as NaI (Tl), LaBr3(Ce), CeBr3.
