Figure 9 PS-I低分辨X－ray nanocrystallography 结构解析装置示意图及结构
答：第一次实验。2011年，Henry Chapman在美国建成的LCLS自由电子激光装置上成功获得了光合反应中心I（PS-I）晶体的低分辨衍射数据。他们将尺寸在0.2-2微米的PSI晶体输送到自由电子激光光束中，获得了衍射数据。这些低分辨的衍射数据和在同步辐射上获得的同样晶体的数据完全一致，证明了利用XFEL可以获得准确的晶体衍射数据。

Figure 10 溶菌酶晶体的高分辨衍射数据
第一次室温下高分辨。2012年Henry Chapman研究组利用LCLS的XFEL获得了溶菌酶晶体的高分辨衍射数据，并利用分子置换法解析出了晶体结构。这次实验使用的晶体尺寸很均一，为1X1X3μm3，获得了1.8埃分辨率的溶菌酶晶体在常温下的结构。此结果表明XFEL可以获得高分辨的衍射数据，而且能够解析出晶体结构。

Figure 11 一种GPCR的XFEL 结构解析
第一次GPCR等膜蛋白实验。Henry Chapman报道了利用XFEL得到的GPCR的高分辨结构该实验证明了膜蛋白结构也可以在XFEL上获得，对于结构生物学研究者是很有吸引力的。
