RADIATION OF ULTRARELATIVISTIC CHARGED-PARTICLES IN A BENT CRYSTAL

The specific radiation accompanying the deflection of high-energy particles by a bent crystal is analyzed. It is shown that when R --> infinity (R is the bending radius) the corresponding formulas are transformed into equations for channelling radiation in an unbent (straight) crystal. Dipole, synchrotron-like radiation and coherent bremsstrahlung in a bent crystal are considered. Numerical calculations of the radiation intensity and energy-loss distributions in a realistic potential of the bent planes have been made for beams with different parameters.
