(I haven't looked for the numbers). This 2009 paper extends Lawson to 3D ... looks to me as if NIF precursors (Omega?) have the same Lawson parameter as Tokomaks -- slides on p33 -- around 5 -- and both need to get to 50-100 for ignition. http://www.lle.rochester.edu/pub/viewgraph/PDF/PR/PRBETTI_NIC09.pdf So I guess I can change my mind.
