• Containment of gun-produced plasma in stabilized mirror fields is studied. Quadrupole and quadrupole-cusp fields are produced by two and four inner conductors, respectively. The plasma parameters are n=10^9-10^<10>cm^<-3>, T_e=1-5eV, T_i (in the mirror quadrupole) >_∼10eV. Flute instability observed in the mirror field is eliminated by superposing the quadrupole field. Superposition of the quadrupole-cusp field does not suppress the instability satisfactorily, but when a wall is provided near the stabilizing winding as in the usual min-B mirror machine the plasma is well stabilized. These phenomena are explained by the stability integral ∫(1/B)dl with suitable integral limits. The mirror quadrupole field whose lines of force fo not contact with the chamber wall has a good stability integral and is promising as a mirror configuration.
