The detector, tagging and date taking systems for the experiment of the (gamma,pi^+) reaction were checked. The photopion energy spectra have been measured using the tagging system at Linear Accelerator Laboratory of Saskachewan University. These energy spectra were analyzed. The results shows that these systems are very useful for the present study, but that it is needed to (i) correct the electron detectors of the tagger and (ii) make a sufficient background shield for pi^+ detectors, especially at the forward.

检查了(γ，pi^+)反应实验的探测器、标记和数据采集系统。利用Saskachewan大学直线加速器实验室的标记系统测量了光子能谱。对这些能谱进行了分析。结果表明，这些系统对本研究是非常有用的，但它需要(I)校正标记器的电子探测器和(Ii)为pi~(++)探测器提供足够的背景屏蔽，特别是在正向。
