DIY Multi-Channel Analyzer MCA project with Gamma Viewer Spectrometer

Video of MCA module connected to Gamma Viewer portable Spectrometer:

You can purchase the MCA module on RH Electronics website. Recommended to buy as a set with compatible  PMT pulse amplifier.
We also accept orders for manufacturing Gamma Viewer spectrometers with new NaI(Tl) crystals:

Arduino IDE Geiger Counter Kit ver.2 RH-K-GK-2-A

What is new in this version?
  • Well-designed electrical scheme and improved PCB layout
  • True voltage feedback in PWM high voltage converter that allows now to drive 20Mega ohm load on 500V
  • Optimized software for fast count-rate condition
  • Second screen mode with CPS counter
  • Fast CPS bargraph with logarithmic scale (great for pancake tube or scint.probe)
  • Native support of 500V and 400V tubes, voltage is set with jumper switch
  • Two LED's with buzzer clicker and mute button
  • Switch between CPM or CPS screen with button
The kit is robust hardware that designed to drive a Geiger Tube while high voltage and pulse counting are controlled by one microcontroller. This is simple and educational project, however load capability and performance of the circuit allows to use this board also in more serious applications, like scientific research or extreme enthusiast tests. Second CPS screen mode with bargraph can be used with sensitive pancake GM tube or with externally connected scintillation probe. 

As before you have:
  • Dose-Rate calculation and ability to calibrate through Arduino sketch
  • Moving average CPM counter
  • UART Logs of CPM value every 10 seconds
  • 16x2 LCD Screen
  • Friendly Arduino IDE source files, open source with buyer
