摘要:
Diffusion of a low‐pressure (10−2Torr) hollow‐cathode discharge through an anode screen produces a linear, homogeneous, and quiescent plasma column (14 mm in diameter, 80 cm in length) in a strong magnetic field (max 3 kG). Electron temperatures and densities in this plasma, as measured by Langmuir probe and microwave cavity perturbation techniques are, respectively, in the ranges of 0.3–1.2 eV and 109–1011cm−3. Plasma noise fluctuations (e&bartil;fl/kBTe) at the center of the plasma are about 3%.
