Fusor Forums

Here is the documentation on the fluorinert cooling of my grid: http://www.rtftechnologies.org/physics/fusor-mark3-index.htm Fluorinert does evaporate slowly (much slower than ethanol), so a mostly closed system is recommended. A simple plastic cap or over pressure vent valve on the reservoir will d...

Fluorinert is best. It has no health issues at all, unless you burn it (don't). https://www.ebay.com/itm/3M-Fluorinert-FC-77-1L-Quick-delivery/264470677091?hash=item3d93ae4663:g:4wUAAOSwpOVdhGs6 https://www.ebay.com/itm/3M-Fluorinert-Electronic-Liquids-FC-40-500-ml/183830136622?hash=item2acd21472e:g...

Welcome to the world of turbos, if all goes well you'll never want to go back to a diffusion pump again. If all doesn't go well I encourage you go get another turbo. A turbo pump is a fine addition to a fusor, hopefully it will give you many years of quality vacuum without any oil back streaming of ...

Here are some x-rays of the board with the LiI(Eu) unit removed

The older pfeiffer TC-100 controllers are getting so cheap on ebay that I would not recommend building your own at this point.

Checking active topics via the "search.php?search_id=active_topics" link is the way I (and probably others) check for new posts on the forum. Access to this link is now disabled unless you are logged in. Also fusor.net keeps logging me out automatically now after some period of time. Do we have a se...

Could we modify the "search restrictions" to allow viewing of "active topics" without having to log in?

I have a mass-producible base-plate design for the anode layer ion source using an aluminum cutout from Front Panel Express IMG_20190320_235610180a.jpg A hermeticallly sealed Pasternack PE4077 BNC connector is used as the HV feedthrough. It's rated to 500v with a dielectric withstanding voltage of 1...

I would like to weigh in strongly against #1 "1. Not all categories are visible without being signed in." and suggest that for #2: "2. Search functions and other parsing functions are not accessible without being signed it" should be modified to allow users that are not signed in to search after sol...

I feel that 17 may be a bit high for the minimum cutoff, I would propose 9th grade. Historically fusors have routinely competed in, and done well in the Intel science and engineering fair. 9th grade is the minimum entry grade for the ISEF fair. The astute 9th grader (certainly not all, but definitel...
