My summer research!

Post by Solo »

Well, it's not fusion-related, but it is plasma physics. I'm working with Dr. Christoph Niemann of UCLA and LLNL/NIF. They've got me apprenticed to a graduate student, making teensy little B-dot probes for a laser-produced plasma experiment. Dr. Niemann is interested in laser-plasma interactions and collisionless shockwaves and Alfven waves, mostly space-related stuff although he does work with the NIF. I'm finding out that there are a lot of similarities between this business and building a house (my occupation for the past few summers).

BTW, this is a paid internship through the NSF (called REU, Research Experience for Undergraduates), which is a very nice arrangement! Other undergraduates who read this, you really ought to apply for some of these programs!

Kewl! I never was terribly handy at making B-dot probes, and Polywell experiments can use them.

....'bitsy ones you say. lots of them. are they digital? why not hall effect?
does indeed sound kool :)

B-dot probes:

Why not Hall effect? Frequency response, saturation, and linearity.

Congrats Solo, thats very cool.
I like the p-B11 resonance peak at 50 KV acceleration. In2 years we'll know.

Thanks all!

Frequency response is the main deal, we're looking into the tens of MHz. Yeah, bitsy, as in, the core I wind the wire around is a 1mm cylinder of plastic with channels cut in it to make 3 axes (axises?) The wire is 40gauge magnet wire. It's very easy to break, about the diameter of a hair. Very finicky, I'm making alot of mistakes.

funny you should say that msimon, i was just looking at that (uni mich) - nice selection of probes and diagnostics (n'shit), theyve got - http://aerospace.engin.umich.edu/spacel ... stics.html

fancy being let loose in there a while? :)

well, linearity, who needs it anyway. frequency response surprises me, thought smaller would be faster. saturation agreed. range, i could understand.

ps. helluva paper here - http://aerospace.engin.umich.edu/spacel ... 8-4674.pdf ... gads

Thanks for the diagnostic link. Added to the sidebar at IECFT.

..you'll be wanting a nanobot for that then?
