FAQ - Extensive paper on neutron activation

Post by Richard Hull » Wed May 09, 2018 6:25 am

We already have a post here on activation, but I put a lot of effort over the past two days to come up with a 6 page document that is much more specific and a lot more of a "take you by the hand" explanation of neutron activation suited for the first timer puzzling over this quest once they have a real fusor running or dare to attempt to activate as proof of fusion.

As the old boys know, it is really tough to prove fusion via activation with under 50,000 n/sec isotropic and over 200,000 n/sec are typically needed for easy to detect activation using good technique and instrumentation as well as using the best of amateur element activation materials. Both of these are tough for first pass fusor operation by the novice operator.

I have struggled somewhat to make sure the content is scientifically correct. A greater struggle was spelling, structure and punctuation.
For those capable of pointing out major errors, I would appreciate any critical comments and feedback so that this paper will serve, well, all who read it in future.

Thanks

I have updated the paper. I used the term collision cross sections.... Corrected to Capture cross section. Updated pricing of Rhodium. A few other nuances added as well.

The 7th edit of the file includes extras suggested by John Futter and Rich Normand. Thanks guys.

Richard
well done
It might pay to indicate early on that the neutron interacts with the nucleus in most situations jiggling/ upsetting the contents and modifying the atomic weight gain / loss (ie isotopic makeup) some nuclear outputs being happy (stable) others in a bind (unstable)

John thanks for the suggestion. I have clandestinely updated the paper over the last few days about 5 times, on my own. I just did it a sixth time and noted it in the original posting. It happens that in re-reading my own paper I found some faux pas worth correcting a sixth time.

I will work on it again. Nothing like making a posting better with suggestions.

Very nice Richard.

1)
I too end up doing revisions a few times on manuscripts, papers and posting to forums. It was easier in the past (review, typing pool, review again, etc...before sending to publisher) but now, with instant posting, I do appreciate the few days this forum allows me to clarify, correct and edit posts.
2)
You might consider putting your name as the author and a perhaps link here in the text proper. The idea is it will probably be forwarded to other people by a reader and attribution for the work will be lost. Your call, off course.

Hope you are enjoying retirement as much as I am. :-)

Rich, I will throw the authorship idea in the mix for the 7th upgraded attachment posting. Thanks for the suggestion.

I will soon delete all the responses as I have given credit for the suggested updates in my original posting.

Rich.... you asked and this will be deleted with all the responses as well

I am enjoying retirement. I typically work in my upstairs lab at night programming, reading and assembling little electronic widgets of my own design.
I write this missive at 2:30 AM. I will be up for another 3 hours at least. I often hop into bed now at 5,6 or 7am and sleep past noon. The peace and quiet of night allows for productive study and hands-on work in electronics. I do walk my one mile in the evenings.

I abrogate many normal duties and responsibilities common to home owners, husbands, etc. It is only when I am forced beyond further denial that I shoulder chores so common to many. My wife held the ladder fast today as I cleaned out gutters for the first time in two years. Loaded with pollen, pin oak leaves that had turned to dust. My eyes still water and the coughing has not stopped.

Yes, 95% of the time life is better than it has ever been. Unlike many of my retired friends, I have a ton of hobbies and never think about or miss the day to day work experience like many of them do. For me, my job was never my life. My job was as that of a happy prostitute where I enjoyed my work, but was there mostly for the money. I had desirable education, training and skills and allowed others to benefit from my application of them for cash. My real life, as I chose to define it, began once I got home from work.
