DIY Kit PMT Divider PCB with Pulse Amplifier for Spectroscopy - for Positive HV

Photomultiplier Divider PCB Pulse Amplifier - for Positive HV


PMT Amplifier PCB with Dynodes Divider for MCA Spectrometry - for Positive HV

Miniature PCB of DIY Kit amplifier for Spectroscopy with Dynodes Divider for Photomultiplier Tube. Works only with Positive Polarity PMT wiring. The PCB has IPX U.FL jack for PMT signal output. The board has two potentiometers for adjusting rising and falling time of pulse. Compatible with our MCA module.

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 include any 0805 resistors. Please check datasheet of PMT for correct divider ratio. 


Technical Specifications:

  • Supports only Positive Polarity High Voltage PMT Wiring
  • Compatible with tubes up to 14 dynodes
  • Input DC voltage for amplifier: 5V
  • Output for Spectroscopy
  • Adjustable Rise&Decay time of the PMT pulse
  • Comes with IPX U.FL jack on the PCB for signal output
  • DIY Kit Require 0805 SMD soldering and PMT wiring
  • Dynodes resistors are not supplied
  • Module diameter: ~45mm
  • Shipping Weight: 150gr


The module uses Positive Polarity High Voltage wiring for dynodes. It mean positive polarity high voltage bias is supplied to pin marked as "HV" and followed by voltage divider over dynodes. Tube's cathode is wired to pad "K" and grounded. Tube's anode soldered to pad marked as "A" with load 0805 resistor marked as "LOAD".

The board has pulse amplifier you need for the initial processing of PMT signal. The amplifier is rail-to-rail high bandwidth OP IC. The output can be used for Gamma Spectroscopy and it compatible with our MCA module. 

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