Query: Re-appraisal and extension of the Gratton-Vargas two-dimensional
  analytical snowplow model of plasma focus - III: Scaling theory for high
  pressure operation and its implications   Recent work on the revised Gratton-Vargas model has demonstrated that there
are some aspects of Dense Plasma Focus (DPF) which are not sensitive to details
of plasma dynamics and are well captured in an oversimplified model assumption
which contains very little plasma physics. A hyperbolic conservation law
formulation of DPF physics reveals the existence of a velocity threshold
related to specific energy of dissociation and ionization, above which, the
work done during shock propagation is adequate to ensure dissociation and
ionization of the gas being ingested. These developments are utilized to
formulate an algorithmic definition of DPF optimization that is valid in a wide
range of applications, not limited to neutron emission. A universal scaling
theory of DPF design optimization is proposed and illustrated for designing
devices working at one or two orders higher pressure of deuterium than the
current practice of designs optimized at pressures less than 10 mbar of
deuterium. These examples show that the upper limit for operating pressure is
of technological (and not physical) origin.
