The planar channelling radiation for the super-relativistic electron is discribed by the classical electron-dynamical method; the spectral distribution and the maximum radiation energy are derived in classical mechanic frame. ch

-2

x potential described to a interaction of particle with the crystal is introduced. As example

the channelling radiation for a electron in the Si(110) planar channel is calculated.It shows that the maximum radiation energy may be represented as ε=ω=57lMeV for a l-order harmonics

the result is consistent with other work. A direction level of the channelling radiation is very well

and the greater part of the energy concentrate in a reqgion with angle width of Δθ≈γ

-1/2

alone the motion direction of an electron

but also the radiation energy is very high.As example

the channelling radiation energy for 1-st order harmonic is ε=57.0MeV for a electron with energy 5.0GeV. Obviously

this energy is located in a γ-region

thus it is possible to take the channeling radiation as a new X-laser or γ-laser. In addition

the polarization level of the channeling radiation is very well also. Of course

take an attempt to reform the channelling radiation as a new type of X-laser and γ-laser require great efforts. It is expected that the coherence of the channelling radiation may be obtained by using a interaction between the channelling radiation and the superlattice with a multi-layer film construction.
