Quick Overview

Dual Output PMT Amplifier PCB with Dynodes Divider for Spectrometry & Scintillation 

Miniature PCB of DIY Kit for Spectroscopy Scintillation Dual Output amplifier with Dynodes Divider for Photomultiplier Tube. Works only with Negative Polarity PMT wiring. The PCB has two IPX U.FL outputs. One is considered for Gamma Spectroscopy and second is intended for Scintillation counter. The board has two potentiometers, one for changing exponential fall time of PMT pulse and second for fine adjusting of pulse threshold detect for scintillation counter. 

PCB supports tubes with up to 14 dynodes. SMD 0805 soldering is required in that DIY kit. You will need to solder dynodes divider with recommended ratio for tube. Because different tubes requries different voltage ratio distribution on dynodes we not iclude any 0805 resistors. Please check datasheet of PMT for correct divider ratio. 

Technical Specifications:

  • Supports only Negative Polarity High Voltage PMT Wiring

  • Compatible with tubes up to 14 dynodes

  • Input DC voltage for amplifier: 5V

  • Dual Output for Spectroscopy & Scintillation Counter

  • Adjustable Exponential Fall time for Spectroscopy

  • Adjustable Pulse Threshold for Scintillation Counter

  • Additional HV filtration

  • Comes with two IPX U.FL outputs

  • DIY Kit Require 0805 SMD soldering and PMT wiring

  • Dynodes resistors are not supplied

  • Module diameter: ~45mm

  • Shipping Weight: 100gr

The module uses Negative Polarity High Voltage wiring for dynodes. It mean negative polarity high voltage bias is supplied to tube cathode "K" and followed by voltage divider over dynodes. The last dynode is tied to ground through last resistor in chain. Tube anode is isolated from divider and need to be soldered to PCB pad marked as "A".

The board has everyhting you need for the initial processing of PMT signal. The first amplifier stage is rail-to-rail high bandwith OP IC. The first output can be used for Gamma Spectroscopy. The second output is intended for Scintillation Counter project and the signal form on second output is compatible with digital counters. 

Take note, SMD 0805 soldering is requried to wire divider for dynodes!
