DECHANNELING EFFECTS OF CHARGED PARTICLES IN BENT CRYSTALS WITH VARYING CURVATURE
变曲率弯晶的粒子退道行为

In the paper, the sine-squared potential and the parabola approximations of a bent crystal with a varying curvature have been introduced to discribe the dechan-neling effects of charged particles moving in such a crystal Furthermore, we show the possibilities of detlecting charged particles by a bent crystal, derive rhe dechan-nelling fraction of such a crystal and discuss the possible applications.
