Today I did a successful test of the Langmuir probe:
Here is a voltage reading of the floating potential:

BIG STEP: Fired the Magrid Coil Inside Vacuum Chamber »
hot damn. How do you move the probe around inside the chamber?
For this experiment is should be fixed at the center of the magrid. However it is on a bellows so movement is possible.
Nice work Mark! :)
How do you intend to calibrate it?
I find it awesome that all your experiment was done at home. I just started working in a plasma gasification lab at my school and I have to wire up the langmuir probre. I am given 2 45V batteries, a 2k linear potentiometer, 4 resistors(10,100,1k,10k) and switch to control the resistance, oh yea and an oscilloscope. Would you have any tips on how to wire it? Anything helps thanks
Thanks Ahead of time
