Moderator Simulation Study

[Carl Willis]

Hi folks,

I have included a Word document with embedded graphs that describes a computer-simulated comparison of three materials as moderators: light water, heavy water, and saturated hydrocarbons. Specifically, this document shows what thickness you need of these materials to get peak thermal or epithermal neutron fluences with a Farnsworth Fusor as the source.

I'll post the other parts of this little project as it continues. Let me know if you have any questions!

Thanks Carl, good info. Just the incentive, (justification?), I need to buy a chunk of HDPE. McMaster-Carr is asking $61.00/foot for 6-inch diameter HDPE. Anyone know of other sources?

Jon - Don't the sources, but you can buy HDPE water pipe up to about 2" wall thickness in all sorts of diameters.. Do not know any prices.

Really nice and useful report, Carl. We all are looking forward to follow-up pieces.

Tks Carl - a good piece of work - joins the reference library and the archives.

Carl,

Anxiously awaiting part two.

Hi Jon,

I need to get a "round tuit"...

MCNP is a powerful tool and Part II (energy-dependent fluxes from Fusor neutrons in large moderators) is a cakewalk. The only problem is that I have my computer, and the 8-processor UNIX machine I use, booked solid with academic MCNP jobs.

I've made a promise to deliver more pieces of this study and so I'll follow through as soon as possible. But that may be awhile!

Also Jon, thanks very much for offering to show me your lab if I ever get out to California. There may be an opportunity this summer since there's a good chance I'll be out west again.

Carl,

I know you're pretty busy, but figured a gentle reminder wouldn't hurt.

The problem is that you did too good of a job on part one, and now I'm hooked!

Hope you can make it to the left coast later this year.

Does anyone have the original file posted by Carl? It seems to be lost / link broken.

Thanks!

[Jon Rosenstiel]

Fixed.
