神光Ⅲ主机通用诊断搭载平台提供各种诊断系统送进和收回的搭载功能，便于诊断系统的拆装和维护保养，同时提供精确的径向、指向瞄准能力，能将诊断系统送至靶室内指定位置，并且能在不破坏靶室真空的状态下安装、调试和维护诊断系统。将通用诊断搭载平台安装在神光Ⅲ原型装置上进行精度检测，得到其真空状态下的径向、X和Y方向指向定位精度分别为36，13，8 μm，全行程的径向复位精度、X和Y方向指向复位精度分别达到20,30,12 μm。搭载分幅相机诊断包进行激光打靶考核，实验结果表明:其指向瞄准精度、真空性能、接口等均满足使用要求，并具备了对抗强电磁干扰与辐射的能力。

The Shenguang Ⅲ facility general diagnostic instrument manipulator provides a diagnostic platform to insert or retract various diagnostic systems into and out of the target chamber. It provides precision radial positioning and pointing capability, and it can carry diagnostic systems to specific position. It can also ensure the installation, debugging and maintaining of diagnostic system without affecting the vacuum in the target chamber. Installed on the Shenguang Ⅲ prototype facility, it provides the radial positioning accuracy of 36 μm, and the pointing precision of 13 μm in X direction and 8 μm in Y direction. Full path positioning repeatability is 20 μm in radial direction, 30 μm in X direction and 12 μm in Y direction. Laser shot testing with X-ray framing camera indicates that, pointing accuracies in X and Y directions, radial positioning accuracy, vacuum capability, interface all meet the requirements of physical experiments. The manipulator also has the immunity to electromagnetic interference and radiation.
