Backdated Oct 19th, 2016:
Everything is finally assembled! As far as I know this is the 3rd FERMIAC to have ever been constructed and the only one outside of a museum. The device is shown here on top of a mockup diagram of a nuclear fuel rod.
The original FERMIAC is almost entirely brass and must weigh quite a bit. This version is very light which makes it quite back heavy, it tips up unless you've got your hand on the thumb screw. I might add some weight to the front to prevent that from happening during use.
I've yet to use it to preform a monte carlo simulation because there are still a few unknowns about the process. I need to find out what the proper scale is for the diagram and I also need tables to select the proper distance measurement settings on drum F. The nature of the random values I need to feed in are also unknown, they follow a distribution that matches certain physical properties of neutrons in different materials, ie absorption probability, scattering potential, etc. More research is required before I can test it out but I'll be filming the process so others can see how its done.
