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!
My summer research!
B-dot probes:

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

Engineering is the art of making what you want from what you can get at a profit.
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.htmlMSimon wrote:B-dot probes:

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.rcain wrote: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.htmlMSimon wrote:B-dot probes:

..you'll be wanting a nanobot for that then?Solo wrote:Thanks all!
