    "abstract": "This paper reviews resent theoretical and experimental research on physical\nprocesses in compensated negative-ion beams. A previous review was published by\none of the authors in Ref. [1]. The present paper summarizes the new results of\nnumerical calculations of the stationary electric field in negative-ion beams,\nand the resent results of experimental studies of suppression of ion-ion\ninstability at low gas pressures. As in Ref. [1], the review addresses the\nfollowing three main issues of the physics of compensated beams: 1) Spatial\ncharge compensation in steady beams; 2) Dynamic decompensation of spatial\ncharge, which occurs as a result of beam current modulation due to plasma\ninstabilities in the ion source; 3) Collective processes. The results presented\nin this review enable one to determine how non-compensated spatial charge,\nnonresonant oscillations of the beam current, and collective oscillations of\nthe ion-beam plasma influence the propagation properties of the beam. With this\ninformation, one can determine the optimal ion transportation parameters.",
