Compton Edge probing basic physics at Jefferson Laboratory: light speed
  isotropy and Lorentz invariance
  We propose to study of the light speed isotropy and Lorentz invariance at
Jefferson Laboratory by means of the measurements of the Compton Edge using of
the Hall A/C existing experimental setup. Methodologically the same experiment
has already been successfully elaborated at GRAAL experiment at the European
Synchrotron Radiation Facility in Grenoble with 6 GeV electron beam. This
Proposal states two goals expected to be reached at Jefferson Laboratory, both
on Lorentz invariance: (a) the one-way light speed isotropy testing accuracy,
following from conservative evaluations at numerical simulations, to about an
order of magnitude better than was GRAAL's; (b) the dependence of the light
speed on the velocity of the apparatus (Kennedy-Thorndike measurement) will be
traced to an accuracy about 3 orders of magnitudes better than the available
limits.
