Re: Joe Gayo's lab tour
Joe, this is a top-flight effort, and I am thrilled to see what appears to be a novel paradigm in fusor efficiency developing in your work. The regime of high pressure, small electrodes, high potential, and high neutron yield is undoubtedly a new domain worthy of further attention. Have you provided...

Re: Low Light Photography
I take low-light photos of radiation-related subjects frequently. I picked out a Fujifilm X-E2 mirrorless camera with that application specifically in mind, and it meets expectations. Obviously, you can spend a lot more money on a better camera and ass-kicking lenses. In particular, this is the doma...

Re: Finally, some more runs of my fusor!
Hi Jamie, This is a very good experiment, incorporating both a moderator removal check and a D2-vs-air check, as well as multiple detectors (you had the EPD area monitor as a back-up, and it got some dose). Neutrons are detectable on the He-3 with the moderator off, but the count is much higher with...

Re: Book about Taylor Wilson is out
Tom kindly sent me an advance copy of his book, which I read last weekend. He has chronicled an inspirational phenomenon in nuclear physics: the ability of an enthusiastic child (a bright one, necessarily with the support of committed parents and mentors) to participate meaningfully in this domain p...

Re: Nuclear measurements on Chicago Pile artifact
I got the green light from the DOE radiological assessment team that takes care of the National Nuclear Museum here in Albuquerque. How the museum wants to display it as a loaned item is still being resolved, but hopefully it will be there soon. On another front, I collected about 250 mg of uranium ...

Re: Please let us know your experience with glass to metal s
Hello Steve, You have described a very challenging seal for a hobbyist to make by himself, and a costly one to obtain from a professional. I think there are preferred alternatives to the glass-metal seal in this situation as you have described it. A master scientific glassblower would make this seal...

Re: Please let us know your experience with glass to metal s
As a very amateur glassblower with a self-sustaining hobby making decorative plasma tubes, I have made tungsten-borosilicate seals via uranium glass and Houskeeper ribbon seals from copper straight to borosilicate. Both types are challenging to perform reliably in my experience. The Dumet or platinu...

Re: Glow in the dark paint
I think a better place for this topic is in the Radiation Detection forum. Some luminous paints are made with scintillating materials like ZnS. Cheap glow-in-the-dark paint from a hobby store is almost always ZnS in my experience, and so is a decent scintillator for electrons. Unfortunately, this pa...
