Abstract

To assure that the frequency conversion crystals of SG facility are always being in the best shot position, and have the highest energy conversion efficiency with various beam conducting directions, we researched the precise tuning technique of frequency conversion crystals with the SG facility. The on-line quick tuning method of target point detecting with preshot was used in precise tuning of crystal match angle, and helped to correct the off-line match angle satisfactorily. With crystal alignment technique and crystal accompany technique, the precise tuning of crystal match angle can assure the crystals to maintain a stable high efficiency in a long experiment period.
