:The practical application of the overlap2contacts technology to SPRITE detectors was introduced and the specific results of the experiment were provided in the paper. The responsibility Rv of SPRITE with the applicable length of the overlap2contacts can be doubled and the detectivity D3 can be improved about 30 % , even 80 %. Experimentally , the performance of SPRITE with overlap contacts was markedly increased , so that the overlap2contacts2technology is an effective way to improve the performance of SPRITE.
