Re: Fusor analogy to quadrupole mass spectrometer

I didn't know my lifestyle had gone "official" ;~} I will say this - it's not a game for old guys, I'm really glad I did most all of the hard stuff before I got old... Now I even have a raspberry pi camera looking at the innards of my rain barrel so I can decide to keep or dump the water without goi...

Re: Fusor analogy to quadrupole mass spectrometer

As to "can't work in a dense fluid with collisions and varying e/m ratios, I give you CERN's project for *high schoolers*. Obviously it can work with oddball e/m ratios and in dense fluid media - this is dust in STP air. We just do in and out instead of up and down as shown here. Think of inside the...

Re: Fusor analogy to quadrupole mass spectrometer

Yep, amazing, isn't it. I believe the reason is that when a normal trap or mass spec runs, it's on the very edge of the stable region - even the particles you want to detect are eventually rejected with a quadrupole's normal operating line. (I used the word believe as I haven't proved it yet - ) I d...

Re: My Visit w Doug Coulter

Well, thanks for the encouragement, and of course, the insights you've shared - many of which were "just" intuition at the time, but which I've since actually measured and proved to be correct! And oh, your habit of hooking up at least one counter to an audio output might have saved my life. I still...

Re: My Visit w Doug Coulter

Pretty much what I read above is correct, FWIW. As John and Bob say, there's more on my site. Which is why you don't see me here that much - I'm busy with my own. Thanks to Bill for the head's up here. He's been kind of a silent (to the world) partner and big contributor to the effort. What I'm tryi...

Re: Archived - OP position progress

Jason, I use my real name (and the silly profile picture) on G+ and am on most evenings EST if you'd like to chat. We can move to other comm as required for security. After that Vice video I've had to be real careful about handing out my email in public - trolls come out of the woodwork. I don't get...

Re: Archived - OP position progress

Thanks, Dennis, I'm lucky to have the time and other resources, so why not max out the fun - with safety? Not all luck, of course, I worked long and hard to get here. Richard is pretty much on target here (doh, as if that were news) - many dream, few do. And of the latter, few can. But what is true ...

Re: OP position progress

Well, even if I wasn't a bit of a luddite about some things (and I surely am), there's also this fact that I'm totally off the grid (solar), and the clock runs a year on an AAA battery and is always-on. The computers, not so much. I hope you can get what you need out of LabView. It didn't look like ...

Archived - OP position progress

Making some progress on the remote operating position for my fusor. Another computer yet to hook up, and a few other details at this end, like the panel hardwired to power relays at the fusor end for "stop this now no matter what" kind of control, but this looks like a fun cockpit to fly it from, eh...

Re: Greg Courville Neutron Club entry Feb 2016

Congrats! Nice work! You'd be welcome in my lab anytime. Having been about where you are - I'll warn you that a little down the road (should you continue) with higher voltages and a need for lower pressure so as to limit current to something not-insane, you're going to need something like a current ...
