    Dynamo effect allows the creation of large-scale magnetic fields through a purely mechanical driving. The efficiency of the process is much higher if the driving is helical. This effect has long been postulated to saturate when the self-generated large-scale magnetic field grows above a certain...

    For the past 15 years, the TS-3 merging project has explored several new types of CT/ST (Compact Tori and Spherical Tokamak): merging formation of FRCs (Field Reversed Configuration), magnetic reconnection experiment, and ultrahigh beta ST formation. The successful results of these experiments...
