Liner compression is an effective way to heat the field-reversed configuration (FRC) plasmas towards fusion condition without spoiling its stability. On the other hand, FRC with very high beta is also a good target for magneto-inertial fusion (MIF), because the drive energy can be efficiently transferred to the plasmas instead of the magnetic field. We show these appealing features in a simple model by including empirical plasma losses, liner dynamics and the coupling to a simple electrical circuit. Based on this model, we present a FRC liner compression experiment. We discuss the importance to choose appropriate machine parameters to optimize the fusion yield. Possible issues associated with the high magnetic field are also discussed. Axial and azimuthal current drives for the liner are considered and compared.
