Exhibit Hall B,
It can be shown analytically that symmetric plasmas, which are composed of positive and negative ions of equal mass, are transported across magnetic fields due to polarization current and the resulting E x B force [A. Y. Wong et al, pre-print]. Such transport would be useful for heating in magnetic confinement fusion reactors, which are bounded by strong magnetic fields. The theoretical requirement for transport, ømega _pi/Ømega _i>>1, has been confirmed computationally using a bounded two dimensional electrostatic particle simulation code [V. K. Decyk and J. M. Dawson, J. Comput. Phys. 30, 407 (1979)]. It is shown that for B = 0.5 T and n_i \ge 10^10 cm^-3, there is little change in the beam's velocity and little spreading of the beam.
