Session 7P - Plasma Applications and Plasma Technology.
POSTER session, Thursday morning, November 14
Exhibit Hall - Concourse Level, Adam's Mark
A distributed plasma source in the form of seven 2-in diam helicon sources in a hexagonal array has been made and tested successfully. Each tube has a helical m = +1 antenna and a dc magnetic field of 0-100G. The plasma is injected into a magnetic bucket, where the density uniformity is measured with a FastProbe(R). In principle, arbitrarily large areas can be covered using multiple tubes, as long as the discharges can be made to fire simultaneously. The ease of adjustment to achieve uniform ion flux in various gases, such as argon and chlorine, has been investigated.
