NaK) and incorporates a large magnetic field coil to provide initial magnetic flux, but these experiments have not yet been attempted. However, Linus O has already provided valuable experience in the handling of liquid liners under conditions of velocity and pressure comparable to, or exceeding those anticipated in a Linus reactor. 

Liquid metal (NaK) liners have been imploded by compressed helium in a smaller apparatus, Helius, which is half the size of Linus-0. In these experiments the payload was helium gas with a small axial magnetic field the field was not large enough to influence the liner dynamics, but was used to study the diffusion of magnetic flux into the liner and to verify a computer model of this process. Note that the transport of flux in a moving liner is... 

In a Linus reactor this pressure corresponds to a peak magnetic field of only a few hundred kilogauss while this is much less than the megagauss fields usually associated with imploding liners, it will be shown later that the overall size of the reactor is almost independent of the peak magnetic field, and there are many practical advantages to be obtained by avoiding extreme conditions of field and pressure. 

A complete description of the operation of a Linus reactor requires a compressible hydrodynamic treatment of the liner motion incorporating non-linear magnetic diffusion at the inner surface, coupled self-consistently to a plasma model which includes transport and fusion energy release. It should be three-dimensional to account for the axial contraction of the plasma, it should include the effect of neutron and breramstrahlung heating on the magnetic diffusion in the liner, and should also treat the evaporation of lithium from the liner and its diffusion into the plasma. 

The basic simplicity of the Linus concept is due to the combination in one element, the liner, of functions which in other fusion concepts require separate systems. It is the confining field coil, the plasma heater, the first wall, the tritium breeding blanket, the heat transfer medium and the main vacuum pump. Perhaps its most important function is that of providing a continuously regenerated liquid first wall whose mean power loading can greatly exceed the limits of a solid first wall.
