Re: Heat pipe cooling
I don’t think vise grips are the answer. Pinch off seals are normally made with more of a cutter type tool. Try using large diagonal cutters.

Re: Preventing Stuck Swageloks?
Sounds like you may be tightening them too much. A new 1/8 inch fitting should only be tightened 3/4 turn past finger tight (1–1/4 turns for larger fittings).

Re: Home built mass spectrometer
Richard, My mistake. I overlooked that you said beta energy. The spectrometers I was talking about are for much lower energy electrons.

Re: Home built mass spectrometer
Richard, Most electron spectrometers used in surface analysis use electrostatic deflection with either a cylindrical or hemispherical analyzer. A cylindrical electrostatic analyzer spectrometer would probably be easier to build than a magnetic deflection machine. There is a huge literature on these ...

Re: Neutron Irradiated Dime REDUX
Richard, Have you considered a thin layer of rhodium plating? There are various rhodium plating services available for jewelry at affordable prices.

Re: MIT claim of fusion by 2025 proving LOL isn't just for the tweeter
The seven papers in the special issue of the Journal of Plasma Physics are available online with open access: https://www.cambridge.org/core/journals/journal-of-plasma-physics/collections/status-of-the-sparc-physics-basis Much of the content of these papers is beyond my level of understanding, but t...

Re: MIT claim of fusion by 2025 proving LOL isn't just for the tweeter
If you read the NYT article carefully, you will see that they just published seven peer reviewed papers in the Journal of Plasma Physics that support their design. I am painfully aware of the difference between a computer model and real hardware, but they have gone much further than most fusion comp...

Re: Earth-tech fusor from 1999
This is a very interesting description of this early fusor. Something I’ve not seen before was his use of the secondary of a neon transformer as a high voltage inductive filter.

Re: Effectiveness of water (H2O) on fast neutrons?
This has been discussed previously at length. Search “water as a neutron shield.”
