What's the price range for this build? I really got into fusion lately, and I've saved about $1,500 over the past couple months. I don't need the best tech, for my first build I can get some cheap parts off Aliexpress.
The last time someone built a fission reactor the feds had to step in and remove things as things were dangerously radioactive. Be doubly careful.
I love the energy this tutorial gives off.
Yes, you can build your very own nuclear fusion reactor in your house! But first, a few warnings...
The fusor is still the best idea from a cost to accomplishment perspective.
Wow people made the Sun. lol
Having built much of a fusion reactor in my apartment... (but not the classic Farnsworth design)
1) A much easier (and usually cheaper and more accurate) way to measure neutrons is to just rent a proper device, from somewhere like: https://instruments.energysolutions.com/instrument-rental/ne.... Not a big fan of bubble dosimeters, except when you need to measure a place you cannot be at the time of measurement (like on the unshielded roof of a linac bunker).
2) Best to check with your significant other before doing stuff in shared areas. Twice I have been banned from "doing science stuff in the kitchen", once when I got a 5" NeFeB magnet stuck to the oven and we almost got badly injured removing it, and once when I thermally decomposed AlOH3 in the oven. This is why the rest of the fusion reactor was not built at home.
3) Power supplies are an important and expensive component. We got most of ours by buying an obsolete ion implanter, and just pulled the power supplies from it. This is a lot cheaper than buying new or even used stand-alone supplies. However, the problem with old power supplies is sometimes they have a problem, and troubleshooting high voltage supplies can be more than tricky. A 180 kV supply got me bad once when the drain resistor was broken and I tried to change a capacitor - when I felt the zap go in one hand and out where I was sitting, I thought "ok, I'm dead". Luckily it wasn't enough charge to kill me. Invest in a long dry wooden dowel, so you can check if surfaces are charged before you touch them.
