The PULSATOR concept for the formation of a quasi-stationary magnetoplasma field-reversed configuration (FRC) by means of cyclic injection and merging of toroids in the confinement chamber is analyzed. The possible use of quasi-stationary plasma accelerators for the formation of high-⟨β⟩ toroids is considered. The requirements for the formation of FRCs with fusion parameters are evaluated. The possibility of the existence of an FRC with a finite toroidal field value is shown. The SAPFIR experimental installation for FRC formation investigations is briefly described, and the results of preliminary experiments are given.
