Archived - First Plasma (American University)
Posted: Fri Feb 26, 2010 6:36 pm
After starting on this project in novemeber, ordering the parts a month ago, we have assembled the chamber, pumped down to 2.8 mTorr, and created a star mode.
I will show you pictures of the chamber, lowest possible pressure, and pictures of the star mode.
The first picture is the lowest pressure we achieved, 2.8 mTorr.
The second picture shows the completed chamber.
The third picture is of an air plasma, star mode, at 30 mTorr, 2000V. Waiting to get a better grids for a brighter, higher contrast pictures.
We have the ability to pump down lower and the ability to go to -18000 V. The wire gets way to hot, so we are working on making a new grid.
More from us later.
Thanks for all your help,
Brian and Bill
