First, I will be upgrading my shielding. I hope to replace my 30 kV power supply and use an 80 kV supply in the near future. That means the X-ray danger then becomes very serious. Following this logic, I intend to install an array of dosimeters and then test my ionization chamber detector, as well. One does need to verify the threat and not just assume all will be well. Like a fusor's voltage, radiation is unforgiving.
Next, add a dedicated moderator system for my neutron detectors. I seriously underestimated the proper size. I see people are using far more than I ever thought necessary. This forum is very useful once again.
Assemble a new Geiger tube - my old one died after many years of service. They only last so long. Naked tubes are inexpensive and creating a full probe is rather simple. Also, allows one to match their preferred BNC system.
The following is totally unrelated to fusors but very important for those interested in a dedicated building.
First off, its a good time to consider doing such a project: that is, if you ever really thought you'd need/want one. The weather is warming, lumber prices are not insane and will only be going up in the future. So, right now is the best time to do this if you really are seriously considering such a future project.
Since I built my lab building a few years ago I would like to say a few things in passing for those considering this type of project (a good idea when one does fusion in a more serious manner. Better still, safer for family members.)
I built my building to match an old foundation I laid down years before for other reasons. Major mistake. One never has enough room and I seriously regret that I didn't build it up to the max allowed by code (before one needs a building permit. Do check that so no one shows up and tells you to tear it down.) I can't believe how quickly one fills all available floor space. I needed an extra table (small) and had to really struggle to rearrange the lab to make enough space. I guess any building is never big enough once it is there to be occupied. Glad I have a real attic in it (do consider that especially for smaller builds.) I really use that to store a lot of currently unneeded equipment.
In any lab one never has enough storage space. So, don't forget shelves - never enough of these either. Always try to add more than you think you'll ever need when planning (and this enable's one to know where to tie in shelve hangers before any walls get covered.)
Also, the primary work bench will, again, never be big enough. Over build that for sure - and add drawers! Maybe a dedicated shelf over it (invaluable.)
Don't forget power: I have a 240 service outlet and double outlets every four feet on all walls. While extension cords with multiple outlets are often needed one really wants as few of them as possible. Yes, a proper breaker box is essential for a separate building (one must follow code for installation.) Also, any out door power wires for the building should be underground and in sealed piping for both their protection and general safety.
Don't forget room lighting: don't over look this. I have two large diode light systems in the ceiling and a portable light.
Finally, security (depends also on your location.) My main door is metal clad, has a dead bolt and the building's windows are too small for anyone to get through. Many of us end up with a lot of equipment and it is a good idea to design the building with these ideas in mind. Also, this prevents curious neighborhood children from accidentally creating issues.
Aside: Well, this post is not technically 'Fusion future' (except for me) but I didn't want to displace some more interesting posts currently in the forum so I placed this here.
). I guarantee you'll use all the space and need more.
