Experiments on the generation of long wavelength edge radiation along   directions nearly coincident with the axis of a straight section of the   "Pakhra" synchrotron
  Generation of long wavelength edge radiation along directions nearly coincident with the axes of straight sections of storage rings and synchrotrons is discussed. The removal of destructive interference from the superimposed edge radiation patterns of a straight section on the synchrotron "Pakhra" has been observed experimentally.
