Fusor Forums

On the GS Neutron detector. We think the shielding was not necessary. But at one point we were getting a lot of noise and needed the shielding. The loose ground on the tube was probably the cause. The GS Neutron is a "sealed" unit, but we disesambled it to do the moderator , no moderator test. This ...

Thanks so much for letting me in the club, it means so much to me, I just want to say thanks and that I will be a contributor to the forum.

Thank you for the clarification. And thank you for telling me I should not post blocks of Quoted text. did not know that. I am a fast learner and will try and do better. I agree my Ag data was hard to read. I dont have enough Ag data to validate neutrons very well. have been focusing on the neutron ...

Again, a bit confused. Previously, you were getting nearly 11 neutrons a second (around 660 neutrons/min) from your fusor as you reported; now you indicate you are getting about 7 neutrons per minute (a rather low rate for a reliable data run.) I should assume the early runs were incorrect? If so, ...

So here is very strong evidense i am fusing deuterium. IMG_2779sm.jpg Moderated run: 6.86 Neutrons per minute Non moderated run: 0.21 Neutrons per minute During 10 minutes of unmoderted run produced a count on my GS-Neutron of 0.21 neutrons per min which is only twice background. In moderated runs t...

Ideally you would use an integration mode for counting as opposed to rate (cpm). - With the fusor off, record the total number of counts for 5 minutes - Run fusor at least 3 times half life to activate the silver - Turn fusor off and record total number of counts for 1 minute then compare to averag...

i did a silver activation earlier this week and made a video. Its decent activation. I am going to do a neutron run this morning, will see if I can get another silver activation while I am doing the moderator vs no moderator. Here is the video: https://youtu.be/BBoL2lVVH8Y Here is the data: Silver A...

I wanted to put together q 3 minute video describing my Neutron generating run setup as reading a spreadheet is not the easiest way to see what was going on. Video of the setup https://youtu.be/t7sQQlOZzOY Video of the actual runs the data came from. ttps://www.youtube.com/watch?v=6GtHVMwKbio&featur...

Suspected that was the issue. You should re-post the corrected results for comments.

I corrected the original post. Thank you again for catching the mistake so quick.

As for the final data you have posted, I'm a bit confused. Your moderated reading is 4.0 neutrons/sec and your non-moderated is 11.3 neutrons/sec. Yet when the detector has no moderator, and since it can't record fast neutrons, its signal should drop to near your noise floor. Instead, it is reading...
