Websurable Lawson criterion is applicable to D 2 surrogate targets and DT subignited implosions. Ignited DT implosions do not require a theoretical ignition criterion to verify that the igni-tion conditions have been achieved. We also show that hydro-equivalent curves can be rep-resented on the same R tot, T i h plane. Hydro-equivalent WebThe Lawson criterion says that PFusion ≥ PLoss. The minimum condition can be derived from the equality, which implies that or from Eq. (3.6) therefore (3.8) Rearranging we get (3.9) Typical minimum values of Lawson criteria for D-T and D-D reactions are 10 20 and 10 21 s/m 3, respectively.
