Diffusion of a low-pressure (10/sup -2/ Torr) 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 10/sup 9/--10/sup 11/ cm/sup -3/. Plasma noise fluctuations (eapprox. =/sub fl//k/sub B/T/sub e/) at the center of the plasma are about 3%.
