Hello,
I'm an undergraduate student, doing an independent research project under a professor this summer. So the experiment I am working on involves using a glow discharge tube, with electrodes at two ends, to create and contain a plasma column. The purpose is to measure and analyze "wave modes" of plasma oscillations (a type of MHD wave) coming from the plasma. Unfortunately, my physics department does not have a glow discharge tube for me to use, so I have to either build it or order it. I have had no experience with glow discharge tubes, so I'm not sure what the best way (the fastest way) to obtain it is. Any ideas would be greatly appreciated.. need to at least finish experimenting before fall term. The specifications (roughly) of the tube should be:
38 cm long
5.5 cm outer diameter
5.15 cm inner diameter
with:
vacuum tubing (i guess for evacuating the tube) is: 3.8 cm diameter
also:
metal plate (allows the gas to flow thru, but defined the plane of the anode, instead of the vacuum tubing acting as the anode) is: 7.7 cm in diameter
How would I go about making this in the shop (with the help with shop technicians)? Or should I order it from an equipment maker (if so, how much)?
THANKS
