Description
We have studied the angular fluctuations in the speed of light with
respect to the apex of the dipole of Cosmic Microwave Background (CMB) radiation using
the experimental data obtained with GRAAL facility, located at the European Synchrotron
Radiation Facility (ESRF) in Grenoble. The measurements were based on the stability of
the Compton edge of laser photons scattered on the 6~GeV monochromatic electron beam.
The results enable to obtain a conservative constraint on the anisotropy in the light
speed variations dc/c<310-12 i.e. with higher precision than from
previous experiments.
