Over 1200 Alnico magnets (1.3 × 1.3 × 4 cm) are used to contain a conventional discharge plasma produced by 1–20 A of emission from 6–48 small filaments at − 60 V. Densities up to 1012ions/cm3are produced in argon at 2 × 10−3Torr. At 5 × 10−6Torr typical parameters are: 8 × 1010ions/cm3;ni/n0≈ 0.7;Te≈ 5 eV;Ti≈ 0.5 eV; noise ⟨ dgr;n/n⟩ ≈ 2 × 10−4; and < 1 nonuniformity over a volume 31 cm diam by 69 cm. Uniform dense plasmas of He, D, and H are also produced. The ion containment appears to be both magnetic and electrostatic.
