Prototype 2 - Detector using fluorescent tubes (improved still unstable)

Note: This project is still very much a work in progress and there are several issues to iron-out, if you have any questions or comments to contribute please feel free to contact me.

I found an easier and more effective way to capacitively couple the High Voltage supply to the gas inside the fluorescent tube using self-adhesive copper tape either side of the tube.

This allows easier wiring and mounting multiple tubes within an enclosure and may also allow for the building of a larger array detector. First I have built a simple two tube detector and after some experimentation I have found a few more refinements to implement into the next prototype coming soon.

Simple two tube prototype in testing

I am currently building a unit Detector Using Geiger–Müller Tubes as a test unit to use as a standard to measure the performance of the Fluorescent Tube Detector against. This will greatly help resolve issues and fine tune the design...
