Re: My Attempt at a DIY Ionization Gauge

Actually this reminds me of this cryogenic thermometer Cody's lab made

Re: My Attempt at a DIY Ionization Gauge

you should calibrate it with a functional gauge and make 5 runs, take data, calculate averages and standard deviation and plot it, it'd give you a great insight and would look much more professional

It does not look pilot actuated. It might work. There are electric solenoid valves with kf fittings, I have one in KF16.
I know, but they are much more expensive

cheap solenoid valve

Has anyone tried this cheap solenoid valves

to hold vacuum for some minutes

i don't expect much from them, but they may be worth a try


Thanks

Re: Has a neutron energy spectroscopy ever been done?

damn, already done, and pretty professional to be honest

Thanks for the link, i looked for neutron spectroscopy, but the search engine splitted the words and was impossible to find anything

Has a neutron energy spectroscopy ever been done?

With the ions colliding at diffenrent velocities, some energy spectrum from the neutrons might be expected Given a detector with a narrow detection energy and placing different amounts of moderator between the neutron source and the detector, with some NIST data the energy spectrum could be retrieve...

Re: Some plasma

Thank you Mr. Hull

i'm really looking forward to produce the neutrons, as an additional project i would like to data log the fusor operation vacuum, kv, current and neutron yield at least

I'd probably open a topic presenting some ideas and techniques that could be useful to others in the forum
