The photomultipliers tube active dividers.

A new approach of powering the photomultiplier dynodes by means of Active Voltage Divider (AVD) is designed.
The AVD consist of high-resistance divider followed by the active buffers based on mosfet (or bipolar) transistors.

The divider is characterized by a low level of current consumption and stability of photomultiplier gain at variable counting rate .

The samples of AVDs for photomultiplier tubes FEU-49, FEU-85, FEU87, R8619, R9800, ET9453KFL, R9779 presented on fig.1-3.
