Created Plasma Lab Wiki

Installed LabVIEW (Joe Weichman)

Data on the density of the plasma versus position in the chamber, close to the plasma source and in the center of the chamber.

 August 4th 2007 Speed of PlasmaA.xls

 

Observations: As pressure in the chamber decreases, the speed of plasma increases. In general, the speed of plasma increases as it moves away from the plasma source.

Observations:

Magnetic Field Inside Plasma Chamber

Plot of magnetic field at 45 Amperes. 

 

Observations: Arrows flow away from plasma source. (Note: the link may need to be refreshed once to work).

Code for a program that calculates the magnetic field strength at a list of points throughout the plasma chamber. b_list.c

Magnetic field every 1cm throughout plasma chamber at 45 Amperes.  Calculated from above  program. b_field_45.txt

Description of the calculation of the magnetic field. bfield.pdf
