      Migma is a self-colliding beam of deuterons, tritons, other beams
which is hoped to bring about Fusion Energy.  It was invented by Bogdan
Maglich, a former Rutgers Physics Professor and Particle Physicist.
Maglich's Fusion Companies were called Fusion Energy Corporation,
Aneutronics Inc., and were probably called other things by the mainstream
Fusion Research Community.

     Actual Migma research facilities were constructed, and consisted of a
nice Van de Graaff  Accelerator (2 MeV???), beamlines, various magnets and
cooling systems, a Migma (collision region) vacuum chamber and
superconducting magnets to make the beam have an orbit in which it would
collide in on itself, thereby creating fusion.  Schematics of the Migma
experimental facility can be found on the internet.  The facility ran for a
number of years, and eventually funding for migma was lost.  There are
scientific papers published on the migma and some of its experimental
results.  There are some scientific graphs showing some fusion output
numbers.

     One set of scientific runs had an input beam energy of 1.35 MeV, which
is quite larger than the energy needed to make fusion happen (20-50 keV).
Maybe running the migma experiment might be better run at energies a bit
above 20 to 50 MeV., but I'm no expert at this.  Scientific Review comments
or the Wikipedia suggests that a Migma beam might lose energy via
Bremsstrahlung if the beam is run at too high an energy.

     I think I remember the Migma chamber having an input beam port which
places the beam eventually to the center of the migma collision chamber.
There might be some ability to adjust the impact parameter (google impact
parameter???) a bit, but perhaps not too much.  Running the beam into the
collision region somewhat tangentially to the outside curved surface of the
beam chamber would require constructing a whole new migma collision
chamber.  And at higher energies, for such a tangential beam input system,
there might be synchrotron radiation losses???  These various beam loss
scenarios might suggest why the incoming beam starts out at energies higher
than 20 to 50 keV.

     The ITER, NSTX etc. traditional plasma physics machines are
alternatives to the Migma.
