Plug-on Voltage Divider Bases
Voltage dividers and voltage divider/preamplifiers allow you to supply the proper operating high voltage distribution to the photomultiplier tubes (PMTs) and to get the signal from them to your system electronics. These devices can be plugged onto or hard-wired to PMTs.
Voltage dividers used by Saint-Gobain Crystals are resistive (or transistorized) devices specially designed to accelerate electrons from the cathode to the anode of a phototube.
There are design considerations when considering electronics:
- What is the application?
- Which PMT is being used and why?
- Positive or Negative HV?
- Count rate: Typical and Maximum
- What are the electronics that the detector will be connected to?
- Preamp question: Charge sensitive or I to V converter
- Charge Sensitive preamps are typically used with shaping amplifiers
- I to V converter preamps are typically used with digitizers
