A possibility for generation of the plasma canal structure at gas breakdown in the axicon caustic is discussed. It bases on increase of the initial modulation with small amplitude, which is present in starting Bessel laser beam. The increase is supposed to be a result of the heating radiation reflection at the plasma boundary with a rather great electron concentration. Computer simulation by the two-dimensional code was carried out for helium breakdown under atmosphere pressure.
