Fusor Forums

Still can't get it to work. I hit the donate button and it takes me to a screen saying "securely logging you in.." with a spinning circle. The spinning circle never stops spinning.

The reports from the Kyoto group of greatly enhanced neutron production were for a titanium anode. In more recent work with a cylindrical fusor, they also used a titanium cathode, but it was a tubular cathode and not a wire grid.. A titanium wire grid cathode would definitely be expected to outgas w...

Richard, do you know a specific model number NIM module that will do pulse width detection? I am not familiar with one that has this specific function.

As discussed here previously, and in my own experience as well, counting neutrons using a Helium-3 detector is fraught with difficulty due to electrical pulses from arcing in a fusor. There are sophisticated methods to do peak discrimination, but I just came across a clever solution that makes use o...

The 21st US-Japan Workshop on Fusion Neutron Sources and Applications (formerly called Workshop on IEC Fusion) was held last month in Kyoto. Unfortunately, I did not attend; but I did see the list of presentations. Most notable to me was an increasing shift from spherical devices to linear devices b...

With the holiday past, I've been able to turn my attention back to my DP5/PC5. Unfortunately, I did not print the responses that were lost on this thread, which addressed issues of powering the boards. Mine will not power up from the USB connection, either with or without the PC5 attached. My intent...

There were some posts to this thread lost. It would be nice if those posting have saved copies they could repost.

There is a good deal available on eBay on current generation Amptek digital pulse processor boards. These are the Amptek DP5/PC5 board combination (see Amptek.com). The DP5 includes an analog prefilter, an ADC, a digital pulse processor and a multichannel analyzer. It is designed to accept a radiati...

You want the knife edges to dig into the copper to make a seal, but you don't have to do it fully the first time. The manufacturers would have you tighten flanges on a new gasket until the flange faces touch, but you can make a good seal with less compression. The key is to tighten sequentially in a...

I typically operate my system at the low end of the 10-7 Torr range and still get 5-6 uses from each gasket by careful tightening.
